Hot Pencil

The
magician shows a pencil that has six different colors on it. A
spectator selects a color and the pencil is sealed inside a metal tube.
The tube is opened and the pencil is dumped out. It has magically
changed to match the spectator’s selected color! The magician offers to
repeat the effect, but the trick back fires – the pencil shrinks! Easy
to do. Full instructions included.
