The magician displays a balloon, a pin, and a deck of cards. He shakes the balloon to prove it's empty and sets it aside. He then aks the spec to select a card which is then folded up into quarters. The magician then takes the balloon in one hand, the card in the other and then proceeds to slam the card right though the balloon! They know it went through because the magician then pops the balloon and the card is found inside! Wonderful trick that can be easily made with items from around the house! The performance video shows the card being signed but this is not covered in the solution, so please note this before purchase.
This trick is suitable for intermediates.
