Card Through Arm Illusion
A plastic plate sitting in a base forms a hole with a movable top part. Remove it to show nothing inside and then put them together. Display a jumbo Spade K with a hole in the middle too, and ask a spectator to examine. Insert the card into the plate from the top, which can be seen up and down within from the hole. Get it out and have the spectator place his arm in the hole . You push down the card from top again, the card ends up with penetrating through the spectator's arm.
