The magician takes out a coin and gives it to the customer. The customer puts the coin into any hand without the magician seeing. However,the magician can tell which hand the coin is put into and he can also know which side the coin is placed.That is amazing! You can perform it at anywhere you want! It includes a electronic detector and a magnetic morgan dollar.
Notice:If you are in other country (morgan dollar for USA),you should prepare magnetic coins for the performance by yourself.
