The mini-brigantine's feature four carbide based cannons. The reason for using carbide is that it is relatively safe and easily handled. It will not explode during transport, cannot be ignited by the hottest flame (eg. no accidental flame ups), it is cheap, and easy to obtain.
Also, carbide has reduced barrel pressures than black powder. As result, lighter and more inexpensive materials can be used to create a basic cannon. Furthermore, if the barrel were to explode the debris is less likely to cause harm than a barrel failure with blackpowder, in otherwords flying or shredded plastic is safer than flying pieces of metal.
For many years, carbide has been used in children's toy cannons, with the largest name in America being the "Big Bang" cannon. Originally, patented in July, 1917, Big Bang cannons have provided years and years of enjoyment for several generations. Today you can do a search on E-Bay and buy and either a used "Big Bang" cannon or purchase a replica. A great source of Big Bang Cannons & supplies is Roy's Big BangŪ Cannons and of course, Big Bang Cannons
Carbide cannons provide a loud explosive sound, and a small flash. However, unlike black powder, carbide produces very little smoke.

Safety First!
It is important to take all necessary safety precautions when building or firing a carbide cannon. These cannons produce a very loud sound and some precautions should be taken when handling carbide. Here are some basic safety tips:
1.) Wear proper eye and ear protection.
2.) Never EVER look into the muzzle of any cannon at any time.
3.) Never shoot any cannon close to the ear.
4.) Carbide warnings: Carbide cannot be ignited by the hottest flame, nor can it be set off by concussion or hammering the grains. However, carbide can be caustic and may cause skin and eye irritation. It should never be swallowed. Try to avoid contact with skin and eyes. In case of contact flush throughly with water. If swallowed give milk or water, followed by citrus juice or diluted vinegar. Seek medical attention immediately.
5.) Carbide cannons should not be operated by minors without proper adult supervision.
6.) NEVER shoot a carbide cannon INDOORS.
