Storm Season


A short explanation of causes:

Tsunami (pronounced su-nah'-me) are huge ocean waves caused by natural forces like underwater earthquakes. Tsunami are caused when the forces of these phenomena rapidly displace large amounts of water.

Most tsunami occur when there is an earthquake or volcanic eruption in the sea or ocean. This is caused when there are plate boundaries that are meeting in plate tectonics processes. This will cause shock waves to be radiated out of the epicenter. This natural event will cause a rise or fall of the seabed. This will create a wave deep in the ocean (or less frequently in other large body of water).

Tsunami can also be caused by landslides, such as a cliff-side of a mountain near shore that falls into a large body of water or ocean.

Powerful bombs, like nuclear bombs, are tested, dropped, or detonated in the sea or ocean and can cause shock waves to be radiated out that move the ocean waters in waves as described above.

They also occur when large asteroids fall into the water. This is extremely rare, and the asteroids must be very large to cause a large water displacement to form a tsunami wave. But they are known to have occurred. Meteorites will not cause high waves as they are usually much smaller than asteroids by the time they have been burned in the atmosphere on the way to the surface.

A longer, more in depth answer:

The huge waves called tsunami are caused by the abrupt vertical displacement of a large volume of a body of water, usually from natural sources of kinetic energy (such as the force of large earthquakes near the shore or underwater). These forces produce a wave that shifts not just a few meters of surface water, but the entire column of water from the floor to the surface. They contain enormous amounts of energy. Earthquakes that cause tsunami often occur offshore at tectonic plate subduction zones. As the sea floor snaps up in response to the tectonic plate movement and subsequent earthquake, the tsunami wave is formed and moves out from the source of the displacement. The wave increases in height as it enters more shallow waters close to land.

They can occur in any large body of water, even in large lakes. An example is the mega-wave that formed when the volcano erupted at Mount St. Helens in the US in 1980. The eruption caused a massive landslide into Spirit Lake and that caused the mega-wave.

To better understand how a tsunami forms, try this experiment:

Get in a pool or the bath tub and put your hand a good ways down and then pull it up quickly but not out of the water, pull up strong but don't break the surface and watch the result. Not exactly a tsunami, but a simple version of the science.


Most tsunami occur when there are underwater seismic events such as an underwater earthquake or volcanic eruption. This normally occurs along plate boundaries. Subduction in convergent boundaries accounts for most tsunami. Subduction occurs when one plate dives under another that is blocking its movement. This will cause shock waves to be radiated out of the epicenter. There will be a rise or fall of the seabed. This displacement of the sea floor will create a wave which cannot be clearly detected from shore at first. These waves can travel at speeds up to 700 mph (i.e. the speed of sound in water) deep in the ocean or other large body of water. As the wave gets nearer to the shore, the wave will compress and gain height in the shallower water. The waves can be up to 100 ft. (30 m) or more when they come ashore.

Tsunami can also occur because of landslides or when asteroids (or very large meteorites) fall into large bodies of water. This is extremely rare, and they must be very large to cause a large enough water displacement to form a massive tsunami wave.


Natural Causes

Besides earthquakes, these waves can also be caused by the forces of other natural phenomena and seismic events that move the tectonic plates, or that directly move the undersea water, or smash into the water surface from above in such a way as to rapidly displace the water.

When it happens in a sea, the sea floor may be deformed from below pushing the water up, or the water can be displaced from an impact coming down on the sea surface from above. Some of the natural causes, other than tectonic plate movements resulting in earthquakes, are huge landslides and other mass movements above or below the water. Sometimes a small underwater earthquake will trigger a landslide that causes a tsunami.

Volcano eruptions in or near the ocean can produce water displacement from underwater or from impacts from above by huge pieces of falling debris from explosions as a volcano erupts along a coastline or near a large lake.

Another cause from natural events is an ocean impact by rare large meteorites or asteroids. This is extremely rare, and they must be very large to cause a large water displacement to form a wave. Meteorites will not cause high waves as they are usually much smaller than asteroids.

Since these natural phenomena can be the causes, it means that tsunami have the potential to be formed anywhere in any large body of water at unpredictable times and without time for any warnings.

Unnatural Causes
An unnatural event with potential to cause tsunami is the detonation of underwater explosions (including detonations of underwater nuclear devices).


The name

The word tsunami is a Japanese term. Japan is one of the most common locations for tsunami. The literal translation in English is "wave harbor" meaning "harbor wave". This name came from the fact that they only become visible as huge waves after arriving in shallower waters near shores and harbors, and therefore, they were originally believed to have originated in the harbor. The word tsunami has been used long enough that it has been adopted into most languages rather than being translated.

The Japanese word does not have a plural form and tsunami is used both for singular and plural in English in many locations. However, it has become accepted over time to say "tsunamis" for the plural in English.

Many early geological, geographical, and oceanographic texts refer to tsunami as "seismic sea waves."

They are sometimes mistakenly called "tidal waves," but tsunami have no relationship to the tides other than looking similar but smaller and generating some similar effects on land with flooding and devastation.

Tsunami are also sometimes incorrectly called "storm surges", which are also different wave phenomena. Tsunami have no relationship to weather. They are not caused by storms, cyclones, hurricanes, or high winds.

Tectonic plate action
Tsunami are commonly caused by seismic activity of tectonic plates (most often earthquakes). As such, they are often found around the Pacific Rim, a region of high tectonic activity in the Pacific Ocean.

A Tsunami can be caused when a tectonic plate in the earth's crust is subducted by another plate, which releases a lot of tensive (potential) energy, in an earthquake. Movement of tectonic plates can cause an earthquake that sends out jolts of seismic activity. Large vertical movements of the earth's crust can occur at plate boundaries. This will cause shock waves to be radiated out of the epicenter. These jolts then can push a tectonic plate under the sea floor, or over or under another plate. The earthquakes can form anywhere there is stress in a tectonic plate, but notably on plate boundaries. Plates interact along these boundaries called faults. Seismic activity is not, however, limited to boundaries of these plates. Tsunami can be formed if there is a very big earthquake any place in a plate that disrupts a water column in a large body of water.

Subduction in the convergent plate boundaries is said to account for most of the tsunami. This natural event will cause a rise or fall of the seabed. When large areas of the sea floor elevate or subside, a tsunami can be created.

This will create a wave deep in the ocean which cannot be clearly discerned from shore. This massive underwater wave transforms when it hits the shoreline and has nowhere else to go but up. This then pushes the water on the surface up, forming the massive wave.

The Greek historian Thucydides was the first to relate tsunami to submarine earthquakes.

Subduction earthquakes are particularly effective in generating tsunami. In the case of earthquake-generated tsunami, there is a major disturbance under water causing the water column to rise as the earthquake uplifts or causes subsidence of the sea floor.

When the sea bed is lifted as a result of an earthquake, the water is also lifted. The size of the wave depends on how high and over how big an area the seabed was lifted. Some say the earthquake size must be at least 6.0 on the Richter scale to create a tsunami.

Tsunami can be caused by very large landslides either falling into the water from above or by an underwater landslide pushing a column of water from below the surface. These mechanisms causing submarine slumps of material, or landslides of huge parts of a mountain or cliff side near shore, can occur without an earthquake, or at least without a significant one. Super marine landslides and cosmic-body impacts disturb the water from above as momentum from falling debris is transferred to the water into which the debris falls. Generally speaking, tsunami generated from these mechanisms, unlike the Pacific-wide tsunami caused by some earthquakes, dissipate quickly and rarely affect coastlines distant from the source area.

Submarine landslides, which often accompany large earthquakes, as well as resulting collapses of volcanic edifices, can also disturb the overlying water column as sediment and rock slump down-slope and are redistributed across the sea floor.

Another type of landslide that can produce tsunami involves the debris delta from a river system that eventually becomes unstable and slides off, thus displacing a large body of water. The rebound to this can cause a large enough surge to be a tsunami, and one with little warning.

Other similar causes in the colder oceans are huge avalanches or glacier calving.

Tsunami can be generated when a violent volcano eruption on land occurs near a large body of water. Sometimes huge chunks of solid rock burst out of a volcano and fall into the nearby ocean or lake making a tsunami. Similarly, volcano eruptions can cause tsunami when they explode undersea. A violent submarine volcanic eruption can create an impulsive force that uplifts the water column and generates a tsunami.

Tsunami can also occur when large asteroids fall into the water. This is extremely rare, and the asteroids must be huge to cause a large enough water displacement to form a tsunami wave. But they are known to have occurred. Some geologists believe as recently as the early 1700s an asteroid impact off the Pacific Northwest coast of North America may have created a tsunami that reached Japan.

These produce a wave that shifts not just a few meters of surface water, but the entire column of water from the floor to the surface. They contain enormous amounts of energy. Tsunami caused by an asteroid impact could be a much higher and more devastating wave, depending on the asteroid's size. Fortunately such occurrences don't happen as frequently as those caused by earthquakes, volcanoes and underwater landslides.

An even more rare cause is a meteorite hitting Earth. Meteorites will not cause waves as high as those caused by asteroids since they are usually much smaller bodies. There are estimates that the space rocks would have to have a diameter of between about 165 feet (50 meters) and 490 feet (150 meters). Any smaller and the rock would have exploded before hitting Earth or Earth's waters.

Underwater Explosions
Tsunami can also occur when powerful bombs, like nuclear bombs, are tested, dropped, or detonated in the sea or ocean or above the ocean waters. There have been tests done in various parts of the world. This was done with nuclear bombs in the area of the Bikini Atoll and resulted in tsunami. A top secret New Zealand program to experiment with tsunami caused by explosions was known as Project Seal, in the 1940's.

This wave is massive - nothing like what a surfer seeks. The waves can be as high as 100 ft. tall when they near shore. They initially will create a series of waves deep in the ocean, that are only a few feet tall. They cannot be clearly discerned from shore or ships until they get to the shallows close to shore and then can be identified too late to allow warning and people to escape.

The largest recorded tsunami was in Lituna Bay Alaska at 1720 feet (524.25600 meters).

Tsunamis move faster than a human being on shore and can not be "outrun". These waves can travel under water at great speeds, up to hundreds of mph. They can travel as shallow waves at 500 mph deep under the sea. Close to the shore, this speed reduces to 30 to 40 mph. Although the momentum slows upon reaching land, it still hits with a major force.

How the waves move
The waves travel in all directions from the area of disturbance, much like the ripples that happen after throwing a rock into water.

The crests of the tsunami waves can be as much as a hundred miles apart. They can cross the entire ocean in less than a day without losing much energy. Tsunami waves can be as long as 60 miles and be as far as an hour and 100 miles apart. They destroy vast cities and developments on land, but at the same time don't destroy ships as they travel beneath them on the way to shore. They can pass right under the ships unnoticed. That's because the height of a tsunami wave might be only a foot or two at those depths. Or they might be noticed but not given any special attention because they seem harmless as they travel under the ocean surface.

The situation changes dramatically when the waves come closer to shore. As they enter shallow waters, they begin to decelerate and gain height as the wave becomes compressed and the seafloor rises in height.

Tsunami travel through water, and therefore can reach areas not located near the epicenter of the earthquake. Reflection and diffraction can change the regions affected. This was seen in the 2004 Boxing Day tsunami, whereby the wave front diffracted around the tip of India and Shri Lanka and hit the western coast of India, a section of coastline that was not in the direct line of the tsunami.

This wall of water travels underwater until it reaches the shore. Once a tsunami reaches the shallow water near the coast, it slows down. The top of the wave moves faster than the bottom, causing the sea to rise dramatically. It will uplift and form the huge wave and as the water gets more and more shallow, it rises and rises until it is at its maximum height.

Interestingly, a tsunami will cause the water along the shore to pull away from shore into the oncoming tsunami, adding more and more water to the "big wave" on its way in. This displacement pulls water back from the shore, causing the wave to build in size and intensity. Depending on whether the leading element of the tsunami is a trough or a crest (it can be either) there may be an eerie ebbing or pulling back of the water along the shore; it must appear to observers like an unnatural pulling back of the tide. This would happen if the leading element is a trough.

Many people get so mesmerized by the unusual sights at the shoreline that they don't recognize the impending danger. Tsunami kill a lot of people because of the fierce strength of the initial wave, subsequent waves, and the undertow created by gallons of rushing water.

Storm Surge vs Tsunami
Tsunami are not caused by storms or wind or other weather phenomena. Those would be storm surges which are different waves.

Some meteorological storm conditions, such as deep weather depressions that cause cyclones, hurricanes, strong winds and other similar occurrences, can generate a storm surge, which can be several meters above normal tide levels. This is due to the low atmospheric pressure within the center of the weather depression. As these storm surges come ashore, the surge can resemble a tsunami, inundating vast areas of land. But they are not one and the same.

Results and devastation of tsunami
As we have seen from the 2004 tsunami of Southeast Asia and the 2011 Japanese tsunami, the effects can be devastating. A tsunami has great energy, and can carry waves far inland. The power of the water can knock down buildings and crush vehicles. People usually die from being smashed against something, rather than drowning. Tsunami can push huge amounts of water over islands and coastal regions causing the deaths of hundreds of thousands or millions of people, and they can cause millions or even billions of dollars worth of damage.

They can move up the rivers and streams leading to the ocean. Flooding can reach land 1000 feet (300 meters) from the coastline and the dangerous waves have enough force to lift giant boulders, flip vehicles, and demolish houses. Tsunami kill a lot of people because of the fierce strength of the initial wave, subsequent waves, and the undertow created by gallons of rushing water.

Tsunami will definitely cause damage, casualties, and injuries. Fires can break out from gas line breaks that are ignited. Tsunami, as they reach closer to shore, will wash fishing boats and other boats, such as cruisers, onto shore, and onto streets, railroads, and buildings. Airports are destroyed, roads are impassable. The boats will be stuck on shore and usually wrecked from the force of the wave. Cars, trucks, airplanes and trains can be washed through the coastal areas damaging structures and people in their wake.

Entire coral reefs and the plants and animals that depend on them for habitat can be devastated. Once the reefs are destroyed, the protection they provided for the coastal areas from hurricanes, storms and other damage is lost along with the barrier reefs.

People and livestock can be caught in the wave and carried away inland and back into the sea with all the debris from the devastation. The waves will also cause fish to be washed onto the shore and stuck there to die. They flood the lands near the shore, causing entire buildings to be inundated. They are identified too late for most people in the coastal areas to escape and avoid death from them. They will damage the crops and cause nearby buildings to collapse. Some people might be trapped under the buildings and die. They uproot trees too, causing them to fall on houses and people.

Lastly, they cause economic decline as countries have to spend billions of dollars rebuilding and recovering from the damage. Millions of people can be homeless without food, clean water, and proper sewage disposal and without electricity. Hospitals that may be still operating are overwhelmed, injured people may not receive timely medical care. Access to medical supplies, pharmacy supplies, and maintenance medications may not be available for months or more. People cannot find loved ones and family members and there are little, if any, means of communication immediately following the tsunami. Factories and jobs are eliminated and many never rebuild in the area again. Tourist industries collapse for even years afterward.

Tsunami "Season" ?
There is no tsunami season, they are unrelated to weather, so they can occur at any time just like the things that cause them can happen any time of yearâ?¦ plate subduction, earthquake, volcano, etc.

Tsunamis can take place at any time; night or day.

Where they occur
Tsunami could occur anyplace there is a large body of water (even large lakes). They can move up the rivers and streams that connect with the body of water of the tsunami, causing further destruction and flooding.

They often hit along the coasts of the "Ring of Fire," around the margins of the Pacific Ocean. In the US: California, Washington, Oregon, and Hawaii and the Japanese coastlines are all potential areas where denser oceanic plates slip under continental plates in the process mentioned above known as tectonic plate subduction. One in Chile sent tsunami warnings ino the pacific. Thailand is in a circle where tsunami hit a lot. There is a well known spot in Alaska where a Mega Tsunami hit, Lituna Bay. There was the tsunami in the Bay of Bengal in 2004.

There was one on October 7, 2009 , originating from an underwater earthquake near the Vanuatu Islands in the southwest Pacific. The wave affected other islands, including Hawaii and Fiji, as well as Alaska and California. This tsunami, however, was weak and insubstantial compared to a devastating tsunami on December 26, 2004, also known as the Sumatra-Andaman earthquake. The wave itself was up to 100 feet (30 meters) high in places. At the time it was considered the fifth worst natural disaster in recorded history, and the deadliest tsunami ever, possibly more than four times worse than the next deadliest tsunami (in terms of death toll, rough estimates range from 229,866 to 443,929 people killed).

Mega Tsunami
Mega earthquakes (measuring 9.0 and above on the Richter Scale) are said to produce Megatsunami (also known as Iminami) which are much more destructive than normal tsunami. They can reach heights of up to 300-500+ meters, and reach about 25 km inland. They are said to be able to cross the Atlantic (Transatlantic).

As mentioned above, an example of a mega-tsunami happened on the 9th of July in 1958 in Lituna Bay in Alaska, generating the largest recorded tsunami. An earthquake measuring 7.7 on the Richter scale caused 90 million tons of rock to fall directly into the sea. It caused a wave 524 meters high (1720 feet).

The wave from the collision of the KT Event 65 million years ago (an asteroid) is believed to have been up to 1.5 kilometers high.

When Cumbre Vieja in La Palma eventually collapses into the Atlantic it could generate a 2000 foot high wave rushing across the Atlantic at 500 mph.

Predictions, warnings, and animal behavior
Scientists are not yet able to predict them just as volcano eruptions and earthquakes can't be predicted. Seismic activity could signal a warning, however, and this is under study.

Animals often recognize the danger and run inland. One explanation of this is that animals can sense the movement of the air and hear changes in the waves much faster than humans recognize these.
Hurricanes and tornadoes are both damaging windstorms, but they are very different phenomena. One is a large weather system and the other is an isolated weather event. A hurricane is a huge airmass that can be more than 1000 miles across, while a tornado is seldom more than 1 mile across, and often much less.

A hurricane (also known as a cyclone or typhoon) is a very large,swirling storm with strong winds and heavy rains. It consists of an area of closed, circular fluid motion rotating in the same direction as the Earth. This is usually characterized by inward spiraling winds that rotate counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. These cyclonic circulations of wind and clouds can sometimes, but not always, lead to a storm characterized by a low pressure center and numerous thunderstorms that produce strong winds and flooding rain. They can only form over warm water with minimal wind shear, but often make landfall at some point as they move across the ocean. While much of the damage caused by hurricanes is from high winds, equally dangerous is its tidal surge, which can flood entire cities, killing large numbers of people.

  • Are hundreds of miles wide.
  • Form only over warm ocean water.
  • Last for days and sometimes well over a week.
  • Produce rain and flooding in addition to powerful winds.
  • Are independent, self-sustaining storm systems.
  • Have winds ranging from 74 to about 200 mph

A tornado is a swirling column of wind that moves across the ground in a relatively narrow path. It consists of a violent, dangerous, rotating column of air which extends from a cloud to the ground. The most intense of all atmospheric phenomena, tornadoes come in many shapes and sizes but are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust. They can demolish entire neighborhoods in a matter of a few seconds to a few minutes.
Tornadoes form from thunderstorms called supercells and reach toward the ground as they develop. Most tornadoes last a few minutes and never more than a few hours. Some last just a few seconds. Most tornado deaths are from flying debris.

  • Are rarely over a mile wide
  • Usually form over land
  • Usually last minutes, rarely a few hours
  • Cause damage via wind and debris
  • Are dependent on a large storm to develop and keep going
  • Have winds ranging from 65 to about 300 mph
  • Often have a condensation funnel.

In summary:
  1. Hurricanes form over warm ocean water as tropical depressions, and weaken rapidly over land. Tornadoes normally form over land from mesocyclones.
  2. Hurricanes are hundreds of miles wide while tornadoes are typically a few dozen yards wide, getting up to two-and-a-half miles wide at most.
  3. A hurricane usually lasts a few days while a tornado cannot last more than a few hours, and some last just a few seconds.
  4. Hurricanes can produce large waves and storm surge, tornadoes, waterspouts and flooding rains. A tornado can be accompanied by these but does not directly cause them.
  5. The strongest tornadoes have faster winds than the strongest hurricanes.

Home Improvement

When it comes to moss or mold on a roof, the culprit is actually ablue-green algae which is most commonly found in warmer, humidclimates. Although it does not damage the roofing the black stainsit leaves do not look good.

One solution if there are only a few shingles involved, would be toreplace the discolored ones with new shingles to match. This meansthat you would either have to have some extra shingles lying aroundor that you could find them at a local supplier. However, if youshingles are pretty old, this may not be possible.

Your options then would be to try to find the closest matchavailable or take shingles from another area of the home that wherethe shingles are less visible and use the old shingles in the spotsthat you want to replace the bad ones and then install the newshingles that don't match as well in the spots where you took theold shingles from. Please see my earlier response to the topic"Shingles" for more on this procedure.

Of course, this problem is going to show up more on lightershingles, so replacing them might be your best option. Howeverthere is a method of cleaning that might just do the trick.

One of the suggestions out there that has been used for years is toget a garden sprayer and mix a 50/50 solution of water and bleachand spray wash the roof to get rid of the algae. Keep in mind thata garden sprayer is not a pressure washer. Do not use a pressurewasher because you can blow the surface of the shingles right offthe roof and thus damage the shingles.

Due to the very delicate bond between the composition shingle andits protective layer of marble chip granules, the use of a pressurewasher is NOT RECOMMENDED AT ALL. If one insists on the use of apressure washer, the spray tip nozzle MUST BE KEPT far enough awayfrom the shingles so that the pressure does not exceed that of anordinary garden hose.

Once even a small percentage of the granules are gone from theshingles, the effect of direct sunlight will accelerate thedegradation of the underlying shingle and destruction of theshingle will occur long before the normal life expectancy of theshingle

A better solution would be to use one of the deck cleaners outthere that are safe for the environment. Products containing oxygenbleach clean well and will not harm the plants. Anytime you can usean product that is good for the environment, the better off youare.

Input from a roof cleaning professional:

There are a few schools of thought on how to properly clean a roof.Based upon my research, years in business and tried and truemethod, nothing is more effective than using sodium hypochlorite,more commonly known as bleach. With this chemical (applied atapproximately a 6% solution with other surfactants) you do not haveto rinse the roof at all. This mitigates all danger of damage fromthe use of pressure. Any pressure is too much. The difference willbe instantaneous. After the first good rain, dead lichen and anyremaining haze will be washed away leaving your roof looking nearlynew.

Here is a common sense thought to add. Hire a professional. I amall for DIY and saving money but sodium hypochlorite will burn yourskin and it can wreak havoc on lungs. It will also kill plant lifeand surrounding vegetation on contact. Professionals will useprotective gear (respirators, safety harnesses, roof protectors onladders, special climbing shoes, etc) as well as protect yourlandscaping from damage.

If the buckling isn't too bad you would detach the board or boardsbut leave in place, and add weight to flatten upward buckling, orturn the board or boards over for downward buckling and then applythe weight.

*If the buckling is due to cupping of the hardwood floor boards asa result of moisture changes, you will never permanently flattenthem with weight. If they are buckled at the joints because theycannot move (expand/contract with seasonal humidity changes) buttheir surfaces are still flat, you might be able to correct thebinding problem and re-lay them. However, if they were properlynailed down, you will not get them up without damaging them. Insuch cases, to fix the problem will require removing and layingdown new boards, being sure to eliminate the problem that causedthis in the first place.
e a spade bit attached to a drill to drill a hole in each end ofthe buckled plank. Set a circular saw to cut no deeper than thethickness of the wood flooring. Plunge cut along the length of theplank from one hole to the other. Make a second cut parallel to thefirst one. Repeat for all damaged planks.

Crafts for Children

Supplies: 2 Popsicle sticks, paper (as many pieces as necessary) , things to color with (all colors is best) (optional, googlie eyes (optional, 1 pair of scissors, and something sticky (glue, tape, or staples).
Directions: outline a face, outline a top hat separate, color (circle/oval like a face, top hat black), outline a body (optional), cut body (if chose a body), color body black like a suit (if chosen body), add tie (if chosen a body, optiona)l, cut through face at mouth line (if you want it to talk), glue top of head to one Popsicle stick (if talking puppet), glue bottom of head to a Popsicle stick (if talking puppet), lastly, glue body (if chosen) to bottom of face.

Corn Dolly!

Well, I can make a yarn dolly. They should be pretty similar.First, you take a long stalk of corn, and wind it around a piece ofcardboard an inch in width as many times as it will allow. Removethe cardboard. Next, tie another piece of straw in the place youwant the neck to be and one about a centimeter from the top of thehead. Cut the fold of straw at the top and bottom of the dolly.Take 3 strands of straw below the neck. Make a tight braid foreach. It should now look like a doll with a head, two arms, and aghost-like body. Tie a piece of straw where you want the legs tobegin. Braid all remaining straw into two legs below the new tie.Tada! You should now have a straw dolly!

Wine Pairings

I would pair cheddar cheese with a nice fruity sauvignon blanc. The semi sweet fruit flavors help cut the sharp flavor of the cheddar cheese. I would recommend a nice bottle of the Seresin Sauvignon blanc!
The classic wine pairing with foie gras is a sauternes. When pairing wine with food one fail safe rule is to pair weight with weight. Foie gras is weighty and rich so is a sauterne.

Sherlock Holmes

He was never actually alive. The fictional stories about him are set in the late 19th and early 20th centuries, from the mid-1870s (The 'Gloria Scott') up to 1914 (His Last Bow), roughly contemporaneous with when they were published.

Dr. Joseph Bell, on whom the character of Holmes was partly based, lived from 1837 to 1911.
Holmes treats Watson like he would treat any other person. Although Watson isn't the brightest bulb in the bunch, Holmes treats him very well. For instance, in the beginning of the book Sherlock Holmes and the Hound of the Baskervilles Watson proposes evidence/clues about a "walking stick" that they found in Holmes den. Watson's clues are way off. Holmes (who already knew who's walking stick it was, and who also knew that every one of the clues that Watson proposed was indeed incorrect) did not say a word to him. So that tells you that Holmes is very good to Watson.
