Chinese Finger Trap
This classic prank fools kids and unknowing adults. Get the victim to push their fingers in both ends of the trap. Watch the fun as they try to get them out. The trick to escaping the finger trap is to push the ends of the trap inward, toward the middle, thereby enlarging the openings. It is a good bet that someone at the party doesn’t know how these work and will get their fingers stuck. That will be sorta fun.
