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.
