how does a carbide cannon work

by Eliane Kunze Published 3 years ago Updated 3 years ago

How does a carbide cannon work? Carbide Cannon. The double replacement reaction of calcium carbide with water produces acetylene gas and calcium hydroxide. Ignite the mixture to catalyze the combustion of acetylene and you have take-off!

These toys operate by introducing a little carbide into a chamber containing some water where it reacts immediately to release acetylene gas. A few seconds later (long enough for the gas to spread out in the chamber, but short enough for it not to be lost out the barrel), it is ignited.

What is a carbide lamp used for?

Small carbide lamps were (and still are) used by miners to produce a very bright flame; larger versions were used on early buses & cars. These toys operate by introducing a little carbide into a chamber containing some water where it reacts immediately to release acetylene gas.

How does a breech block work on a cannon?

At the rear of the cannon is a breech opening. The breech block was fitted with a little spoon that held the correct amount of carbide. When the breech block was inserted into the cannon and turned 1/4 turn to lock it in place, the carbide was tipped into the water and the gas was formed.

What happens if you add too much carbide to an explosion?

Deliberately adding too much carbide does not increase the energy of the explosion but instead weakens it. Since a means for producing a consistent gas charge was important, a special granulated form (about 1 mm grains) of calcium carbide was trademarked as Bangsite in 1952.

How do you ignite calcium carbide?

Part A. Add about 5 g of calcium carbide to the water and let the reaction bubble for 15–20 seconds. 3. Bring a lighter to the top of the water and ignite the acetylene gas that is produced. It should burn for a few seconds with a small “popping” sound.

How do you make carbide explode?

Is calcium carbide explosive?

Calcium Carbide reacts with WATER and MOISTURE to produce flammable Acetylene gas and Lime. The heat of the reaction may ignite the Acetylene. Calcium Carbide reacts with COPPER, SILVER, MERCURY and BRASS to form explosive compounds such as METAL ACETYLIDES.

What happens when calcium carbide reacts with water?

Calcium carbide is not volatile and not soluble in any known solvent, and reacts with water to yield acetylene gas and calcium hydroxide.

Is carbide still available?

Despite these problems there are three dealers that sell calcium carbide: Inner Mountain Outfitters, Karst Sports, and Rocksports Emporium. You can find both Inner Mountain Outfitters and Rocksports Emporium at different caving conventions, and it may be possible to buy calcium carbide from them face to face.

What does calcium carbide look like?

Crystal structure. Pure calcium carbide is a colourless solid. The common crystalline form at room temperature is a distorted rock-salt structure with the C22− units lying parallel.

Is calcium carbide illegal?

The Food Safety and Standards Authority of India (FSSAI) has banned calcium carbide under the Prevention of Food Adulteration (PFA) Act, 1954. Anyone using it can be imprisoned for three years along with a fine of Rs 1,000.

How do you neutralize calcium carbide?

Calcium carbide can be neutralized by adding various types of alcohol, such as ethanol, isopropanol, resulting in acetylene, vinyl ethers, calcium alkoxides and higher alcohols from decomposition of calcium alkoxides.

Does calcium carbide go bad?

Calcium carbide reacts to moisture and that includes moisture in the air. If you live in a humid environment and keep your carbide in a can or tin that allows the air to get in, then it will begin to degrade. If you vacuum seal your carbide, you can expect it to last virtually forever.

Is acetylene a gas?

Acetylene is a colorless and odorless gas. Commercial grade Acetylene may have an Ether-like or garlic-like odor. It is used for welding, cutting, brazing and soldering, and in making other chemicals. Acetylene is shipped under pressure dissolved in Acetone or Dimethylformamide.

What is the other name of acetylene?

Ethyneacetylene, also called Ethyne, the simplest and best-known member of the hydrocarbon series containing one or more pairs of carbon atoms linked by triple bonds, called the acetylenic series, or alkynes.

What happens when calcium carbide is treated?

When calcium carbide is treated with water acetylene is formed.

When was calcium carbide invented?

Calcium carbide was one of the first products of electric arc furnaces, made economical by Niagara Falls in 1888. After cooling, irregular chunks were packed in air-tight containers for sale and used to generate acetylene gas by slowly dropping water on them.

What is a big bang cannon?

Big-Bang Cannon. For other uses, see Big Bang (disambiguation). The Big-Bang Cannon is an American toy cannon first manufactured in the early 20th-century. Numerous consumer fireworks injuries convinced a physics professor at Lehigh University ( Bethlehem, Pennsylvania) to patent a "Gas Gun" in 1907, and the manufacturing ...

What was the original gas gun?

The original 1907 “Gas Gun” patent does not claim novelty for the idea of using carbide-produced acetylene to produce explosions in a toy; rather it was the combination of a gas generator, ignition means, and various parts which were cheap to manufacture.

Where are Conestoga cannons made?

The Conestoga Company manufactures nineteen models of Big-Bang Cannon in Allentown, Pennsylvania, Lehigh County . A bombing plane, tank, boat and pistol were manufactured during the 1920s, firing on the same principle as the cannons. 1930s designs included a Giant Roller Coaster, Ro-To-Top, Spinning Top, Field Glasses and G-Gun.

When were big bang guns invented?

Numerous consumer fireworks injuries convinced a physics professor at Lehigh University ( Bethlehem, Pennsylvania) to patent a "Gas Gun" in 1907, and the manufacturing of Big-Bang Cannons started in 1912, from the Gas Cannon Company.

How to fasten a shield?

Fasten the shield in place by bending over the tabs with a hammer ( flat side of shield is the interior side). Lift the Lock Pin (Barrel Rivet) and put the barrel in place so that the Lock Pin (Barrel Rivet) will enter the hole in the upper side of the barrel.

How does Big Bang work?

BIG-BANG ® works like an automobile engine, using gas , air and a spark. Keep it clean and never use an "overload". Follow instructions and never abuse or misuse Bangsite ® and BIG-BANG® CANNON. Each single-shot breech loading cannon is packed with Breech Block in place.
