OVERVIEW
A finger trap (also known as a Chinese finger puzzle, Chinese thumb cuff, Chinese handcuffs and similar variants) is a gag toy used to play a practical joke on unsuspecting friends. The finger trap is a simple puzzle that traps the victim's fingers (often the index fingers) in both ends of a small cylinder woven from bamboo. The initial reaction is to pull their fingers outward, but this only tightens the trap. A great classic gag!
