Who wouldn't be delighted to watch their money magically grow? One by one, the magician drops a nickel, a dime and a quarter into an empty tube, shakes the tube, and doubles each coin until there are two of each.
At the end, the quarter multiplies into 8 quaners. Using the enclosed bonus gimmick, you will be able to produce a huge pile of coins from the tube. It's like hitting the jackpot.
