Bending Spoon - Boxed
Show a packet of cards with spoons on the face.
Ask a spectator to sign the card on top of the packet and then put this card face down on your hand. Do some magic gestures over the card and, finally, turn it over.
Everybody will see the signature… and the drawing of the spoon, originally normal, will now look mysteriously bent!
An Amazing visual effect!
Easy to do!
