A large firecracker is displayed and placed inside a metal tube. The tube is capped and given to a spectator to hold. When the tube is opened, the firecracker has vanished - in its place is a red handkerchief. When the spectator removes the handkerchief, it explodes with a “BANG”.
Ask a spectator to hold out their hand and make a closed fist. Pull out a marker and draw an X on the center of your palm and close it into a fist. Now without any rubbing, erasing or funny business, you slowly open your hand and reveal your X is COMPLETELY GONE. Now ask the spectator to open their hand - THE X IS ON THEIR PALM!
