Two coins are examined by your friends (a Quarter and a Penny) as you explain the different metals they are made of.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.
Comes with a gaffed coin and online instructions.
You supply the matching regular coins.
Available in US Quarters or US Kennedy Halves.
