How To Make a Dead Simple Air Conditioner Out of a Milk Carton



The RcLifeOn YouTube channel has a simple but ingenious way to beat the summer heat. All you need is a milk carton, a computer fan, a little hot glue, and some soldering skill.

The video shows how to cut a fan-sized hole in the bottom of your carton, glue the fan into place, and then wire it up either to a battery or to a 12-volt AC adaptor. After the carton is then filled with ice, they turn on the fan and a flow of cool air begins to creep out the pouring spout. (Note that you'll need the long, slender variety of ice cube to fit through that opening.)

The carton AC may not cool your home, but it could be a nice way to get a flow of chilly air going by your desk and survive the summer.

Very ingenious idea. I wouldn't go through the trouble of making one as my desk fan works for me.
