How many times do I have to tell you kids!? It looks like German chef Heston Blumenthal blew off both of his hands while "trying to empty a canister of liquid nitrogen." The use of liquid nitrogen is apparently part of some discipline called molecular gastronomy "a scientific discipline involving the study of physical and chemical processes that occur in cooking." (thx wikipedia)!
I, personally, feel it's a little over the top using something that boils at -196 Celsius in your cooking, no matter how bad ass you think you are. Hadn't this fellow seen Terminator 2?
UPDATE: Despite several sources claiming it was Blumenthal himself who destroyed his hands, it now appears it was an unknown German chef attempting to use a method commonly used by Blumenthal. (Thanks, Graham!)
