This is a performance worthy piece using two square chimneys each 6 inches high and 3 1/4 inches square along with a solid wood block of 2 1/2'' for an effective and visual penetration through a 5 3/4'' square of plex.

The plexiglass is placed between the two chimneys stacked one atop the other. The bright yellow wood block is dropped in the top chimney and it magically passes through the center obstruction falling out the bottom of the lower chimney!

Twenty or so years ago a gentleman purchased one of these from me and later brought back a video of his performance at a picnic and he introduced the effect as one fit for a block head and he actually had someone up from the audience and had the block pass through the gentleman's head! It was a funny bit.

Includes 1 page of illustrated instructions.

Condition: Very Fine and has designs that are uncommon to this set.
