This is a DOUBLE penetration that is both VISIBLE and amazing!

This unique set comprises a simple tower, two blades, and a 3" block. The blades are placed through the sides of the tower and the block is dropped in. It rests on the upper blade. A magical tap and the block VISIBLY penetrate the first blade!

The first blade is removed and the block now visibly penetrates the second blade which is removed and the tower is lifted to reveal the solid block resting on the tower's base.

Only one block is used and there is no sleight of hand involved. Everything is done in the open and can be performed surrounded.
