Back in the mid-1960s, I saw an educational film about the senses and in it was an exposure of some magic sleight of hand, specifically some billiard manipulations and the cups and balls. For a long time I thought it was part of the ubiquitous Bell Science series starring Dr. Frank Baxter, but when I finally located a copy of "Gateways to the Mind" I found out I was wrong. It was one the events in my life that spurred my interest in sleight of hand. Does anyone know the title of this film and who the magician was? I recall that they never showed his face, you just saw his arms and torso. I would like to see that film again.
