The instant the coin is out of sight, extend the last three digits of your right hand and secretly retract the coin. Make a fist with your left — as if holding the coin — as your right hand palms the coin and drops to the side.
Your brain’s inability to sense small changes, its desire for constancy, your inherent desire to feel like you are in control of unconscious decisions … this is the neuroscience that illusionists take advantage of. Fascinating read.
