It’s Tenyo’s Mystic Blackboard.

Show your audience a board containing an illustration of a spoon. Ask a spectator to sign the board, proving that no switches will take place.

Cover the board and make a magical gesture. When you remove the lid, the illustration now shows a bent spoon!

You may think that this is a new application of the Out To Lunch principle. Mayyybeee. But, where’s the rubber band? There isn‘t one!

You will be able to magically alter drawings on the blackboard despite the fact that the board is signed.

This is a goodie!
