In this instructable I will show you how to make a pocket sized BB/Spitball shooter. From its name, the gun shoots BB pellets, paper, tissue or any kind of projectile the would fits inside its the barrel. I sometimes use multiple amount of BBs, now it works like a shotgun. It usually creates very loud noises, it's ideal for new years eve. There are several uses for this project, you can use it for fun or even self defense.
How Does It Work:It work when you put alcohol inside the chamber. In the combustion chamber, flammable materials gets ignited by the electric igniter (piezoelectric sparker), then when the gas or liquid gets burned it quickly creates a large amount of pressure inside the chamber, when the chamber gets pressurized the projectile exits the barrel at a very fast velocity. Since Alcohol is flammable and cheap I decided to use it. Different kinds of flammable gas or liquids can be used for better results.
