Bang on the Money by Martin Peirce
Instantly and Amazingly add up randomly chosen combinations of coins.
Includes 7 specially printed double sided plastic cards and full instructions.
5 double sided cards are introduced with random amounts of money on each side. Your spectators are invited to put the cards in any order, face up or face down, to create a random amount of money.
You can 'mentally add up' the total in about 2 seconds!!!
Two more cards are added, but amazingly you still add up the total in 2 seconds.
(The amount written at the top is covered!)
Finally, you can have your spectators mix the cards, total up the amount and place the cards stacked in your hands. You then feel the 'Weight' of the coins and reveal the total!
Bonus finale included!
