Make science feel like magic with every spin of the Centrifugal Force Keychain! This pocket-sized puzzle keychain is a cleverly constructed coin trap challenge for any brainteaser buff.
With a metal coin securely trapped inside a plastic case by eight small beads, it appears like a small shake or shimmy of the case will release the coin, however, the trick uses a bit more finesse. The only way to set it free is to put the wonder of physics at work!
With centrifugal force, a quick spin of the keychain will push the beads out of the coin's way, allowing it to slip through the crack! Celebrate mastering physics, and then return the coin inside the case so you can challenge your friends to solve the puzzle.
