@chris Paleolithic humans had a life expectancy of 33 years at birth; life expectancy went up to 54 years if they made it to age 15. Neolithic man had a life expectancy of 20 years (this was after the agricultural revolution when diets changed). Current life expectancy is 67 years.

is there a beer chilling contest? I think a DefCon entry would probably need to have a usb powered spinner.

Since you're rotating it around its long axis the beer doesn't actually get agitated, the rotation provides just enough internal movement that the cold temperature is quickly spread throughout the liquid; similar to the way that a thin layer of water will freeze more quickly than a deep pool.
