Two cubes are displayed, each of a different color and size. One cube is inserted into a tube, and a thin stick is inserted from the side, locking that cube in place. This cube can be plainly seen the entire time through a window on the tube. When the magician taps a second cube against the bottom of the tube, this cube instantly penetrates inside of the tube, ending up skewered on the thin stick! You can also magically remove a cube that had been locked inside the tube by the stick.
Although the cube is locked in place by the stick, and inserted inside of a tube that leaves no room for any secret switches, you can transpose the two cubes under these impossible conditions.
You will enjoy the visual shock of this instantaneous transformation, as well as the clever secret that eclipses the imagination of laymen and magicians.
