No Paper Paper Trick
Effect: The magician divides a piece of small sticky paper into 4. He then writes 1,2,3 and 4 on each of the parts. Then he adds a "+" symbol in front of the 1 and 4 and a "-" in front of 2 and 3. He makes a fist and says "1+4=5 but 5-2-3=0" as he does this he stuffs all the paper into the fist, he opens the fist and nothing is left in his hand.
Secret: It all goes as described up until you make a fist. You're really just sticking the paper into your thumb tip.
