About David Blaine

David Blaine has become a household name because of his TV specials where he performs death-defying acts. He's been called a "modern-day Houdini" for being buried alive for seven days, frozen in a block of ice for nearly three days, and for standing atop a 100-foot pillar in Manhattan for 35 hours.
