Most talks on the brain science of illusion feature slides or recordings, but the presentation last night at AAAS in Washington, DC, offered illustrations in four dimensions—a live performance by mesmerist Alain Nu. “The Man Who Knows” treated us to a series of experiences hard to explain but easy to enjoy. I’m going to describe a bit of what happened but you may want to just jump to the event’s video below to see for yourself, for reasons I’ll get to in a minute.
For example, Nu showed us a can of soda, popping the top, pouring soda into two ice-filled glasses, crumpling the can a bit as he invited two volunteers to quaff it down. After they had, Nu’s hands danced around the can, and its bends slowly straightened—and then it was full of soda. He popped the top, and poured more soda out, to the evident enjoyment of the two volunteers, who got a second helping. How did he do it? After his set, Nu joined three scientists who told us we’d only fooled ourselves.
