It’s been really hot here in Pittsburgh the past few days, and finding ways to beat the heat have been paramount to getting anything done. My strategy has been to be nice to people who have A/C. Michael Colombo, however, decided to take matters into his own hands, and set up the above DIY Evaporative Cooling system. We’ve covered homemade air chillers before, but this has to be the simplest- just set out a dish of water in front of your fan, and you are good to go. Michael also points us to an explanation of the wet-bulb temperature, which is a measurement of how cool you can expect an evaporative cooler to work in your conditions.
