Down the hatch takes more work than it appears

Talk about thirsty. The water-gulping feat in the trick shown here doesn't quite demonstrate Kobayashi-level skill, but it's still a shock to watch. In a tremendously un-scientific test, we determined that it would normally take about 12 seconds for the water to empty out of a similarly-sized bottle held upside down. This drinking champion does it in under five.

The plastic bottle is critical. If he were just holding it upside down, gravity would be doing most of the work, and that's just not fast enough. Instead, he squeezes the plastic bottle, forcing half the water out. Next, he wisely pauses for a moment there in the middle of his chug, allowing air to creep up through the water and into the space between the new, lower water level and the interior bottom of the bottle. Without that, the pressure exerted would be too great - he wouldn't have been able to overcome it and suck down that last bit of water. So he lets the air flow up, lets the bottle expand and regain its normal, uncompressed state, and then crushes it again, forcing that final enormous gulp down his throat. A champion indeed.—Gregory Mone

That was drinking, this is clapping http://www.youtube.com/watch?v=PNXElmEUIJo&eurl=http://popsci.typepad.com/popsci/the_breakdown/index.html
This is a must post!!

It should be noted that forcing yourself to drink too much water all at once can kill you by diluting your blood and causing severe brain damage. Yes, it takes far more than the fellow drinks here (over a gallon for an adult), but one should be careful about drinking too much while practicing this sort of stunt.

I think you were too quick to forget the man who died of drinking too much water not so long ago
