How did the drinking bird from the 1960s work to continue to bob its head into a glass of water?
The classic bobbing or drinking bird toy has amused kids and adults for years. It appears to be perpetual motion (impossible) but is actually a heat engine with a lot of thermodynamics going on. Although the bird is often thought to be a recent invention it was invented in 1945 and patented in 1946. The "toy" was the brainchild of to PHD candidates, Miles V. Sullivan and George H. Shackley. The science is so complex that it has been the basis of several thermodynamics courses.
The classic bird is made from two glass bulbs joined by a glass tube. The tube extends almost to the bottom of the bottom bulb. It is joined to the top bulb but only at the end. The bulb contains some fluid which evaporates and condenses easily at about room temperature. The bird so far is similar in construction to the "love meters" which move fluids from one bulb to the other based on the heat of your hand.
The other parts of the bird are a bird beak or head made of absorbent material, a pivot which lets the bird balance on a stand, and a glass of water for the bird to dip its beak into. The actual operation of the bird is the result of several gas laws, evaporative cooling and, pressure changed due to heat, leverage and showmanship!

What is the coolest tech deck in the world?
The "coolness" of a tech deck can be subjective, but the Lexus hoverboard, developed with magnetic levitation technology, is often considered one of the coolest tech decks. It allows riders to hover and glide over surfaces, creating a futuristic and exhilarating experience.
What was the coolest pinball machine in history?
there is a bad told tale about: a huge pinball machine, that you enter inside the ball.
and two friends hit it with the pin or whatever the people calls. they said: it travels around the globe in: amusement parks, fun parks, carnivals and circuses. but never comes in my town, but you can search for a list of the places they intended visit
What causes the air pressure inside an inflated balloon?
The elastic contraction of the rubber in the balloon's membrane causes the pressure in the air inside an inflated balloon.
When you inflate a balloon, you have to expand the latex of the balloon, which stretches when filled with air from a pressure of 760 mm Hg to as high as 840 (about 10% higher than standard atmospheric pressure). If you inflate a non-elastic mylar balloon, it takes no effort: the air inside is at the same pressure as the air outside.
Where is the carnival in round rock?
The carnival in Round Rock is typically held at the Old Settlers Park during specific events or festivals. It's best to check the official Round Rock city website or local event listings for exact dates and location.
Which of these is a zone in which one plate is pushed down into the mantle underneath another plate?
This is known as a subduction zone. It is where one tectonic plate is forced beneath another due to tectonic forces, resulting in the recycling of crustal material back into the mantle. These zones are often associated with deep ocean trenches and volcanic arcs.
How do you make bouncy balls with borax?
The balls will flatten out after sitting for a while, but storing them in small plastic containers and then rolling them between your palms again will help the super bouncy balls regain their shape.
This is what you'll need: borax (found in the laundry section of the store)
When you hold a yo-yo in your hand what kind of energy does the yo-yo have?
When you hold a yo-yo in your hand, it has potential energy due to its position above the ground. This potential energy would transform into kinetic energy as the yo-yo falls and unwinds when released.
How do you win in a snowball fight?
To win a snowball fight, aim for your opponent's body, particularly their torso or head. Move quickly and stay agile to avoid getting hit. Use teamwork and strategic positioning to outnumber and outmaneuver your opponents.
What is the mass of silly putty?
Silly putty was made for rubber in world war 1. They made it by acident too.
What is the density of a wooden yo-yo?
The density of a wooden yo-yo can vary depending on the type of wood used and the specific dimensions of the yo-yo. However, on average, the density of wood is around 0.5-0.8 grams per cubic centimeter.
Amargo fossils can be found in certain regions of South America, particularly in Argentina and Brazil. They are often discovered in sedimentary rock formations that date back to the Late Cretaceous period, about 70-80 million years ago. Paleontological sites such as Neuquén in Argentina are known for having yielded Amargo fossils.
How do you get hurricane in steel sentinels?
To obtain Hurricane in Steel Sentinels, you need to engage in naval combat and defeat the Steel Sentinels faction at sea. Once you defeat them, there is a chance that a Steel Sentinels ship may drop the Hurricane schematic as loot. Keep battling the faction in naval combat until you obtain the blueprint.
Are LEGO magnet mini figures just ordinary LEGO mini figures?
LEGO magnet mini figures are similar to ordinary LEGO mini figures, but they are attached to a magnet base. This allows them to stick to magnetic surfaces like refrigerators. They can also be detached from the base and used as regular mini figures in LEGO play.
What forces are used for a rubber duck to float?
The two main forces that allow a rubber duck to float are buoyancy and gravity. The buoyant force exerted by the water on the duck is greater than the force of gravity pulling it down, allowing it to stay afloat on the surface of the water.
What portion of the plasma membrane are made up of fatty acids?
Approximately 50% of the plasma membrane is made up of fatty acids, which are essential components of phospholipids forming the lipid bilayer of the membrane. These fatty acids provide the plasma membrane with flexibility and help regulate its fluidity.
What is the name of the person who cares for nature?
A person who cares for nature is often referred to as a naturalist or an environmentalist. These individuals work to protect and preserve the environment, conserve wildlife, and promote sustainable practices to ensure the health of the planet.
Is there a alley marble in a game of marbles?
An alley marble, also known as a large shooter marble, is typically used in games of marbles to shoot smaller marbles. It is often the marble used to start the game by knocking other marbles out of a circle or target area.
What force causes a yo yo to slow down and stop?
The main force that causes a yo-yo to slow down and stop is friction between the yo-yo string and the axle of the yo-yo. As the string rubs against the axle, it generates heat and dissipation of energy, leading to a decrease in the yo-yo's rotational motion until it comes to a halt.
How do you make it harder for a balloon to pop?
To make it harder for a balloon to pop, you can try inflating it less so there is less internal pressure, using a thicker balloon material, or keeping it away from sharp objects or rough surfaces. Additionally, avoiding overinflating the balloon and handling it gently can also help prevent it from popping.
Why doesn't silly putty break when pulled slowly?
Silly Putty is a non-Newtonian fluid, meaning its viscosity changes with stress. When pulled slowly, the molecules have time to align and flow, giving it its stretchy and elastic properties. This allows it to deform without breaking, similar to how some types of gum or dough behave.
I tried making Gelli Baff and managed to make my own one, i used:
Sugar, food colouring (of your choice), bicarbonate of soda, milk powder and a small amount of water.
if you leave it to stand for a few hours it should go to the right substance.
In Pokemon emarld where is doven he research on reviving Pokemon fossils?
In Pokemon Emerald, the researcher on reviving Pokemon fossils is located in the Fossil Maniac's house in Fallarbor Town. You can find him by entering the house and interacting with him to revive fossils into Pokemon.
When you increase the rate at which the spring toy moves left and right, the frequency of the wave it generates also increases because each oscillation completes in a shorter time. This results in a shorter wavelength since the distance between successive crests (or troughs) of the wave decreases as the frequency increases.
