Show a pencil and a tube. Ask your spectator to remember the color of the pencil as you put it into the tube. Now let your spectator open the tube and dump out the pencil. The pencil has magically changed color!
But wait- that's not all! The pencil has also SHRUNK!
So easy to do- full instructions are included. If you can put the pencil into the tube- you can do the trick!
And that's all you need!
