Here's a compilation i made of footage from the Beer Cooling Contraption Contest at DEFCON this summer. The rules are simple... contestants are given room-temperature cans (which quickly start to rise to outdoor temperature in the Vegas heat) and have to pour the contents through a device of their own creation in order to drop them to a proper drinking temperature.
I run this contest every year as a way to kick off DEFCON... so if you feel like trying your hand, swing by at noon on Friday, either to play or just to enjoy free beer! More details and past results here...
A big thank you to all the people who showed and offered their advice, thermometers, or overall energy to the competing teams in order to make the the contest better. And an extra-big thank you to JVR, without whose tireless assistance this contest wouldn't be possible.
