The scary card trick by Jim Pace. This is the trick that makes them scream. Four blank cards are counted onto a spectator's palm, they're counted again and pictures of a Spider's Wen appear on the faces of the cards. To conclude they're asked to wave a hand over the cards - as they do this they discover a large plastic spider on the back of their hand. It was undetectable, as it's loaded way ahead. A scary trick that should only be performed at the right time and place, when it is, the response is unprecedented.
