Many of us take for granted that we have certain resources available to us and don’t even think about what it would be like if we didn’t have them.

This DIY project is certainly a good thing to know, since we can’t always count on our air conditioning units. And, if, or when, they go out, it’s usually the hottest season of the year!

I think we can all agree that one of the greatest inventions of all time is our beloved home air conditioning! There’s simply nothing better than coming home on an insanely hot day to a nice cool home.

Unfortunately, it’s a luxury that some of us can’t necessarily indulge in all of the time, since air conditioning can result in some pretty hefty utility bills.

The greatest thing about this DIY is that it’s portable—it works great at kids’ sporting events, backyard barbecues, and especially convenient for working in a hot garage.

So, what can you do with old plastic bottles? Not much, you’d think, apart from recycle them. Except you could make a zero electricity air conditioning unit.
