Fire Piston


Demonstrates how the compression of air increases temperature and pressure inside a cylinder. A small piece of cotton is placed in the cylinder. After being rapidly compressed, the cotton ball will ignite and force the piston back up. This wonderful demonstration tool vividly demonstrates the principles behind diesel engine operation. Includes 2 spare O-Rings, and a small piece of starter cotton. Instructions included.
