Get a kaps on fire wallet. This effect is very cool and has a surprise.
EFFECT: You bet a spectator that you can find their card in one chance. You have them pick a card and sign it. They place it into the pack and it is shuffled. You try to find their card a few times unsuccesfully. You then go through the pack face up and their card is not there. You then say that since you never found thecard you owe them some cash. You open up your wallet, all of a sudden 6 inch flames jump out. you close it. shake it. and open it again. You can show that there is real money and credit cards inside. you unzip a compartment and inside is their signed card.
The only things you'll need is the wallet, a deck of cards, a sharpie, and lighter fluid.
It only works with lighter fluid which can be bought at a local hardware store.
