One spectator will be able to know the identity of another spectator's card!

The SPEX GLASSES will allow you to perform this MIRACLE anytime, anywhere with anyone!

A card is selected and lost in the pack of cards. Ask a second spectator to put on a pair of SPEX GLASSES. Borrow a lighter or smartphone, and ask this second spectator what he sees through the glasses. He'll see the card visibly MORPH on the flame of the lighter or smartphone light as if it were a ghost vision. The card's name eerily appears!
