An empty metal tube is shown to a spectator, then a patterned pencil is pushed into the tube and sealed inside with a small lid.

The tube is shaken lightly and then handed over to a spectator. The spectator is asked to open the lid and remove the pencil.

Upon opening the tube the pencil is seen to have disappeared and now a small different color pencil is tipped out. That's Magic !

 

Very easy to do self working magic.
