The Hunter

The Hunter Demonstration. The apparatus consists of a cannon arranged to fire a delrin ball propelled by a blast of compressed air. The cannon is aimed at a stuffed toy bear supported by an electromagnet at the opposite side of the lecture room. The electromagnet circuit is completed by a pair of wires arranged in front of the cannon muzzle. Wires must be in contact before firing the gun, to complete the electromagnet circuit. As the projectile leaves the cannon the bear is released.
