A block of wood is shown and clearly marked for easy identification at a latter time. Also clearly shown are two empty tubes with small windows on them. The block of wood is clearly visible through these windows.
You hold one tube near the right ear and the other tube is held near the left ear. The block of wood is placed into the right tube and it is clearly visible through the windows on the tube. In full view of the audience the block of wood passes through your ear and head and comes out through the other ear.
The tubes are once again shown to be empty and the wooden block handed out for inspection and to verify the markings.
This is an very visual trick that is very easy to do. You don't have to be a block head to make the block pass through your head!!!!
The block measures about 2.5" x 2.5" x 2.5" and the tube measures about 11" in length. This is a very well made wooden prop that is very inexpensively priced.
