Netflix has a new magic six-part series called Magic For Humans. The show's star, magician Justin Willman, worked with an audience to help him pull off the trick in this clip. Working together, they make two guys believe they've become invisible, and they really, really do believe they can't be seen. (I was a little worried about the second guy. I think "being invisible" broke his brain.)
“When I was a kid I put a tooth under my pillow, went to sleep, and in the morning there was money there. That tangible evidence was more than enough proof to make me believe in the tooth fairy. To find out how far I could take that premise, I set up a large flash-mob style social experiment all to convince one guy he had turned invisible.” - Justin Willman.
