Very easy magic that seems to happen right in the spectator's hand!
Show a regular looking pen to the spectator. Place the pen into the tube and close the tube with a lid. Have the spectator hold the tube. Let the spectator open the tube- and find that the pen has changed to a pencil!
Special thanks to our friend, magician and legendary radio personality Lou Dean, for helping us demonstrate this effect.
And that's all you need!
