A shell casing is a piece of ammunition that is made of metal. It is often brass, but it can be made of other metals as well, and the more durable the better. Shell casings can be made from any kind of ammunition that is fired from a pistol, rifle or shotgun. It is not a bullet, but it is a piece of the larger ammunition mechanism that is loaded into the chamber to be shot.
Ping-pong balls. Ping-pong balls are made from the wood component celluloid, a mixture of nitrocellulose (used in nail polish) and the plant-based plasticizer camphor. Celluloid is used in ping-pong balls because it is easily moulded and shaped, while allowing for the high-bounce property of the balls.
