Three flat plastic rings with a beautiful golden finish are shown to be exactly what they seem -- three flat gold rings. But then -- they begin to melt through each other in an amazing and bewildering manner. Even when held by a spectator, two single rings slowly and openly link and unlink, and then you add a third one. After one of the rings visually penetrates a ribbon, the three rings are passed around for complete examination. This incredible routine was a smash hit on Petrick's worldwide lecture tour. Rings are 5" in diameter. $60.00
