Sitting at your desk or laying in bed in the heat is miserable. Because you have no air conditioning (or your unit isn't working properly), there's no sign of relief. And that fan you've set up on the window only blows more hot air.
Instead of wilting away, you can make your own DIY air conditioner with either of two methods. Both methods use materials found at your local home center or hardware store. Within a couple of hours, you'll be cool and comfortable as your DIY air conditioner blows chilled air your way.
