Two beautifully made wooden tubes are shown alongside a wooden block and a wooden sword. The tubes are stacked into a hollow tower and the sword is inserted into the center of the tower. The block is dropped thru the top only to be stopped by the sword. The tower is tapped and the block passes thru onto your hand. Once again the block is dropped into the tower to repeat the trick. The block stops as before but the magician taps and the block does not pass thru. The tower is taken apart and the reason for the block not passing is that it is now impaled onto the sword. Beautiful teakwood is used to manufacture this effect and it is built solid to perform for many years!
