Double-block penetro

The performer shows a tube, a small iron bar, two blocks, and a lid. He inserts the bar into one of the two blocks and places it inside the tube. Then he places the other block on top of the block trapped by the bar. He covers everything with a lid. He snaps his fingers, slams the lid shut, and when he removes it, everyone will see that the trapped block is now free, while the other is trapped by the bar!

• Very fascinating close-up effect.
• Everything is elegantly and carefully crafted from teak.
• The tube measures 6.5 cm (2.56") x 13.5 (5.31") x 15.5 (6.1"). The blocks measure 4.5 cm per side.
• Everything can be examined upon request. The audience can even choose which block will be trapped in the pole first!
