A pretty cool DIY air conditioner --- Pun intended! :)

If your home is like an oven but you are too much of an ecologist to think of using an air conditioner, you can try to keep cool with this DIY project.

In this case, a copper tube, a battery-operated water pump, and two plastic tubes are sufficient to turn a simple electric fan into an air conditioning system.

In addition, since the refrigerator freezer always stays on, producing ice will not increase the total amount of your electric bill.
