A red tube is shown empty to the audience. An empty cup is passed through the tube and comes out the bottom. The cup is then filled with water, and then poured out into the tube. Mysteriously, the water does not come out the other end! It is magically suspended in the center of the tube! For a finale, the empty cup is passed through the tube again, only this time, it comes out full of water!!! Water can also be colored for visibility.
