This is a great opener for at the table or parlour routines. It gets your spectators involved, chatting and in your confidence as you demonstrate why, as a magician, you always win. This is done by tossing a coin a few times and correctly calling how it lands. Of course, you get a laugh when you show that you are using a double sided coin which you pass out for inspection.
Then it's your spectator's turn to try. Let's say the coin is a double sided heads. After the coin has been inspected, you show it on heads and turn it into your other hand. It shows heads again. You do it again, it's clearly the only coin you are holding and it obviously goes onto heads again. You then turn it back into your other hand and ask them to call. They say heads. When you show that it is now on tails, they are flabbergasted and blown away. You then say, "I did say that the magician wins every time".
This is easy to learn with the step by step, detailed instructions with close up and slow motion footage. It won't be long before you are able to perform this and get great reactions.
Please note, a double sided coin is not supplied with the purchase of this trick.
