David Blaine: 'Drowned' Alive

I'm sure you guys know about David Blaine new challange right..submerged in a human aquarium and plans to stay there for a week... now is that crazy or what?? but im pretty sure he need some magic to stay alive in there..can't imagine a week without going to toilet..then if he survives his seven-day endurance test, Blaine will handcuff himself to 150 pounds of chain and then remove his breathing apparatus. He hopes to break the world record of almost nine minutes without breathing... may god be with you blaine.. :P
