Here are just two of the many effects possible with the X-Tubes: The magician borrows any bill and places it into the tube. Amazingly, the bill disappears and a thank-you note appears in its place, with the proper denomination written on it! The magician fills one tube with rice, covers it with the other tube and shakes it back and forth. To everyone’s amazement, the rice seems to have doubled in quantity! A small amount of the poured out rice is put back into the tube and again covered with the other and given a shake. This time, water is then poured out and both tubes are shown empty! No switching of the tubes. Everything may be examined before and after. Precision-crafted from durable plastic. Includes six routines and a set of three tubes.
