Derren Brown, the british ‘psychological magician’
(for want of a better term)
will attempt this live on tv, you can even apply to be the person who loads the gun.

he has previously been able to do Bruce Lee’s one inch punch, read minds, predict outcomes etc
and he always states he is doing it by using psychology, not ‘magic’
A very interesting guy
