Slivki Show demonstrates how you can use a couple of cheap computer fans, a plastic tray, and some water to turn a brick into a desktop air conditioner. The porous nature of the brick, and the cutouts in the one used here, turn it into a surprisingly efficient cooling device.
Has your car’s air conditioning lost its cool? You could go to a repair shop, wasting time and money, or buy the A/C Pro Recharge kit, which lets you fix your A/C yourself in less than 10 minutes with no tools. After a few quick steps, your car will have the #1 coldest air.
