It's not a trick, it's a test of brain power. How do you get the coin out of the Key Chain? For those reading this, yes the clue is in the title. Use centrifugal force and you'll find the coin escapes the trap.

If you look closely you will see lots of tiny ball bearings within the casing. When spun the centrifugal force moves the ball bearings away from the coin which then escapes the trap!
