Three 10p Coins are Inserted into a Black Plastic Case and are COVERED by a Sheet of Paper.
The lid is closed, locking the coins in place. Then, a Pencil is Pushed directly Through the Coins.
A Spectator can even Plunge the Pencil Through the Coins.
Without Funny moves or Sleight of Hand, the case is opened,
the paper is removed, and the Coins are seen to be Unharmed.
Very Easy to Do.
