EFFECT: The magician shows the audience what he calls a "Portable Hole." Sure, it might look like an ordinary piece of clay, but he offers to prove it by pushing his magic wand inside. Holding the clay in the palm of one hand and the wand in the other, the magician proceeds to push the wand entirely inside the clay! The audience can still see a small white spot in the clay which looks like the tip of the wand and they can completely examine the clay.
