You show a black keychain made with a glass dome to the spectator and you explain that this keychain can catch his thoughts. The spectator picks a card in the deck, remembers it and puts it back into the deck. Then you ask him to imagine that he mentally cut a corner of his card and threw it into the keychain while you are shaking it and magically the corner will appear in the keychain!! Then you go through the deck, and you see a card without a corner, you turn it face up, it’s insane! This is the spectator’s card and the corner in the keychain matches with the card. You can give the keychain to examination.

This is not shown in the teaser, in the tutorial a method to do the reveal in the spectator’s hand is also explained.
• Everyday carry.
• Reset fast.
• Easy to perform.
• Visual.
• A pure design.

WARNING: Dôme gimmick is made with a glass dome so be careful to not letting it drop on the floor it could break.
