The magician offers his spectators some pistachios and also eats one himself. He then picks one up and rests it on top of an upside down glass. Now for the really incredible part, the magicians makes a magical pass with his hand near the glass, and the pistachio visibly penetrates right through the solid bottom of the upside down glass!
A killer effect!
• Very easy to do. • The cups are normal and not supplied.
