Astonishingly amazing

I can't imagine how can one could possibly sniff one whole glass of coke with his nose. In normal circumstances, with all the gases in the glass of coke how could he do it? Whenever I drink a glass of coke, I could hardly do it so fast.

Tell me, is this guy real or what? or is this just a stunt? He did it in front of so many audience, that could not be fake right? I must say that I'll give this guy credit for doing this stunt. What say you?
