While there are many professional escape artists - entertainers that specialize in freeing themselves from shackles under stressful conditions - few take it to the level Wisconsin daredevil Anthony Martin does. He has escaped from under 2,000 pounds of sand, a steel cage submerged in ice-cold water and even some of the world's most secure prisons. However this latest stunt definitely ranks as his most dangerous one yet! What is even more incredible is that this is the second time he has been able to pull or should we say escape it off!
