David Blaine is relatively well known American magician, illusionist, and also an endurance artist. He is known for his insane tricks, that even though we know it’s not actually magic, makes us question how it was done. In a way, we all wish for the tricks to be real.
What Blaine is also known for is pushing the boundaries of human limits. Can superhuman feats be accomplished? Blaine does exactly this when he shows prisoners how to bend the bars. Is it actually real? There is speculation that the section of the bars were actually staged, and could be turned to reveal the bent side.
