A US penny is displayed and placed on the edge of a house key. It instantly bonds to the key with a strange force. It can be pulled and tapped on the table, but it won't break loose. At your will the penny is released. You then repeat the demonstration with a dime, again the dime clings to the key. You can hand the key and dime to a spectator and they will not be able to remove it. Instead of a key, the coins can bond to a US quarter. Includes precision made coins along with printed and video instruction. Easy to do.
