Dr. Michael Rubinstein – Fusion Coins Quarter (Gimmick not included)

Two coins are examined by your friends (a Quarter and a Penny) as you explain the different metals they are made of.<br.
You then place the Penny on top of the Quarter and after a little squeeze the penny sinks into the quarter and is fused inside. The odd new coin can then be examined.

You pick up the coin, give it a little shake and the penny falls out leaving everything examinable and ordinary.
