Magician David Blaine thrilled inmates at a U.S. jail by performing a free show last month (Jul14).
The famed illusionist treated around 60 prisoners at the Manhattan Detention Complex in New York to a series of mind-boggling tricks, including levitation, during the hour-long show.
He even made jokes with the inmates about some escapology moves that could help them slip out of their cells, according to the New York Post.
One guard tells the publication, "He was levitating and teasing inmates with tricks on how to break out of here. You know that isn't happening."
A prison spokesman says, "The Department of Correction uses positive reinforcement as one of many strategies to reduce inmate idleness and improve facility safety. Inmates who attended this event were being rewarded for good behaviour."
It is not the first time Blaine has performed at a prison - in 2006 he gave shows for inmates in Arizona and Louisiana.
