Pyrotechnics and Fireworks

fireworks are only legal in the north in Ireland. if you are in the north you must have a licence to buy sell or use.

But at the same time there are firework shops up north that will allow you to buy without licence but these are normally shops that appear before Halloween and new years.

The first documented use of fireworks dates back to 7th century China during the Tang Dynasty. Developed using a combination of incendiary powder inside bamboo shoots, the Chinese used these early fireworks for entertainment and celebrations.

Some rockets are used for space travel and others are used for war. some other rockets are hand made like baking soda rockets.

Rockets carry satellites and astronauts into space, missiles, distress beacons, even pyrotechnics (fireworks) for amusement.

Burning wood is an example of a chemical change. In this process, the cellulose molecules in wood react with oxygen to form carbon dioxide and water vapor, changing the composition of the wood and creating new substances.

Burning a paper. Any change where you can't go back to the original item is a chemical change. You can't go from ashes back to a paper.

Crumpling a piece of paper is a physical change because it's still a piece of paper.

you get a strip of paper (bout computer paper size and about 2 inches wide)you have to have 3 sparklers and get a piar of plyers and get an extra piece of paper and fold it in half.you get your plyers and cut the powder into find powder and fold the strip of paper that you cut and make like a lillte flag but fold it 3 times.put all of the powder into the flag shaped .after that keep folding it just like a flag.her a little tape and tape the holes and get 1 papper clip and bend it into a standand tape it on.get a lighter and light the tape.and that's how u make one its really cool but it lasts like 5 secounds but its worth it.thanks for the question.and good luck!

ORRRR you can go out and buy a huge pack of em

Firecrackers represent energy change as well as the preservation of force. To extend the explosives up requires transformation of compound energy to motor energy. The active energy is utilized to conquer gravity and is changed over completely to possible energy all the while.

The whistling sound could be due to a leak in the intake system, such as a loose hose or a faulty gasket. It could also be caused by a damaged or worn-out turbocharger or a worn-out serpentine belt. It is recommended to have a mechanic inspect the vehicle to determine the exact cause of the issue.

Ever see a firework explosion that WASN'T round? Everytime you see a fireworks explosion, you are seeing it from the side. The "side" you see is not the same side someone 200 yards away would see. Nor is it the same side someone a mile and a half away would see.

Think of a lightbulb. When you turn the switch, an "explosion" of light particles is ejected from the filament. The particles of light all come from the center and travel at the same relative speed in every direction. In a fireworks explosion the same thing happens. A small center (the filament) explodes and sends tiny particles of burning matter, all moving at the same relative speed, in all directions making a "ball" of light. Just like a basketball, no matter what side you look at, it's round.

There's an exception to this answer==If it is a kind of breezy night--The Fire works don't always fall straight to the ground--They sort of float in one direction==Not staight down!!Al;so did you ever view fire works from up in an airplane==Very different!!

To remove slime from the bottom of a vinyl pool, you can use a pool brush or scrubbing pad to physically scrub the affected area. You can also try using a vinyl pool cleaner or a mixture of water and vinegar to help break down the slime for easier removal. Regularly cleaning and maintaining your pool's pH and chlorine levels can also help prevent slime buildup in the future.

You can buy Egyptian wine in the UK from specialty wine shops and online retailers that offer international wines. Some websites might carry a selection of wines from Egypt or you can also check with local wine merchants who specialize in unique or hard-to-find wines.

Earliest use of fireworks was by the Chinese 2,000 years ago.

Gunpowder was invented during the Song dynasty (960-1279) and fireworks followed.

The Chinese people celebrate the invention of the firecracker every April 18 by celebrating the inventor Li Tian.

Their is a small time fuse or a spolette (black powder filled tube) inside that ignites when the black powder lift charge goes off and sends the shell into the air. The time fuse or spolette is timed to burn until the shell reaches it's apex which differs for each size shell. When it gets to the top it passes the fire to a burst charge which is usually black powder coated rice hull but for smaller shells they sometimes use a stronger break such as KP, H3 or flash powder.

When the heater is off but heat is still coming out of the vent, it could be due to residual heat from the engine or a problem with the cooling system. This could be a sign of a faulty heater control valve or a malfunctioning blend door. It's best to have a mechanic inspect the vehicle to diagnose and fix the issue.

It is generally better for a repossessed vehicle to be sold at a public auction to reach a wider customer base and potentially secure a higher selling price. Public auctions also provide transparency and fair competition among buyers.

Vinyl liners have a tendency to stain. If a brush won't work, you can try using a large chlorine tablet to "brush" the stained area. Please use caution - bleach tablets can burn skin and eyes - wear goggles and gloves! More input from FAQ Farmers: * Ascorbic acid will remove stain from a vinyl lines. First try a vitamin C tablet on the stain and see if it works. It should work almost immediately. Using ascorbic acid followed by MetalOut in a 0% chlorine pool will work. * I tried the ascorbic acid suggestion and it worked great. But rubbing the lining with a sock full of vitamin C tablets was time consuming. Can I add granular ascorbic acid to the pool water and have it do the same thing? If so, will that damage the pool liner? If not, what ratio should I use? * You can purchase granular ascorbic acid for just this purpose at any good pool supply store - I get mine at Leslie's. Follow the directions on the bottle (including the use of a chellating agent). This will not damage your liner. * These are more than likely not dirt stains, but metal stains. Swimming pools can get all kinds of metal satins, but the most popular ones are copper, iron and organic. And yes, the ascorbic acid will work great to remove the stains. To prevent the staining, you need to use a sequestering agent to keep the metals 'tied up' in the water so they cannot attach themselves to the liner.

The blast of firecrackers is an illustration of substance change. During a compound change, substances are changed into various substances.

Interesting question; the only real way to answer this is by estimating an average. It is an impossible question to answer with a solid answer.

I will use Canada as an example here.

there are approximately 2 doctors for every 1000 people here in Canada. (60,000) there are approximately 8 nurses for every 1000 people in Canada. (160,000)

If you assume that each doctor and each nurse use say (for the ease of mathematics) 10 gloves a day

220,000 x 10 = 2.2 million per day

2.2 million x 365 = 803,000,000 million per year in Canada.

The U.S.A has aproximately 10 times the population of Canada so you would get about 8 billion gloves per year.

this does not include other professions that may use gloves (paramedics, fire, police, security,)

When all is considered, 10 billion gloves might be a reasonable estimate.

There are countless sources of imagery that MacLeish put in this poem. One of them is in the first stanza. The "globed fruit" is being compared to a poem. A fruit is juicy and tasteful. For the most part it is known around the world as being a fruit. MacLeish's poem implies that the more literal imagery you have the better your poem is. Which obviously doesn't make any sense. But I guess the poem doesn't really make much sense either =>

She knew that Angela was the bomber and also knew she would eventually confess. Turtle set off the fireworks so no one would suspect Angela. Turtle is also a more likely candidate for the bombings.

The custom of watching fireworks on the Fourth of July could be studied by various social sciences, including cultural anthropology, sociology, and cultural studies. These disciplines would examine the historical and cultural significance of fireworks on Independence Day, as well as the social and community aspects of the tradition. They would also consider how the custom reflects and reinforces national identity and values.

To make the factor firework for 84, you need to find all the factors of 84. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. You can use these factors to create different combinations and arrangements for the firework display.
