Coin In Nest

{SKILL LEVEL ONE - See "Skill Levels" at left}

A borrowed coin is marked by a spectator. The coin is then wrapped in a hanky and given to spectator who holds it over a glass. The coin is dropped into the glass, but when the hanky is removed, the glass is empty.

Now the magician places a circular box on the table. Spectator opens the box to find another box inside. This continues until five boxes are opened...the fifth containing the marked coin.

Easy to do.
