Nothing big or special. I punched some holes into the bottle and made it drip onto the towel that was wrapped around the box that contained our snacks etc. Had a fan pointed to the towel. That is all. Evaporative (heat) loss is the keyword. What made me remember this, was the fact that I was in between about 2000 hackers who probably all thought about this.. but that I was (afaik) the only one who actually did it. In Nigeria they use more or less the same trick to build simple air-conditioning. Imagine it as a wood box open on two sides with a lot of small brittle branches inside. Water dropping into it. And a fan blowing on one open side. btw: although mixing up brought and broad is something that I could have found myself and is a result of being sloppy; I always appreciate input on my writing. As English is not my native language, I would guess that my grammar sucks more than my spelling. :)
