DIY Eco-cooler is a cooling system consisting of used plastic bottles and a piece of cardboard.

The mechanism of Eco-cooler is such that the temperature of the hot air rushing in to the bottle is expanded before cooling takes place as the air passes through the neck of the bottle. The temperature is reduced by 5°C within a short time.

To make A DIY Eco-cooler, take the following 6 Steps

To make a homemade cooling system, grab a piece of a heavy duty cardboard and trim it to fit the window of your choice.

Next, cut holes in a grid pattern that are large enough for a bottle neck, but be sure the cuts are spaced out according to the size of the bottle.

Find as many used bottles as you can, and the bigger the size difference between the body and the rim, the better, notes Eco-Cooler.

Slice along the body of the bottle and cut away the tops of the caps before placing them back on the bottle – this helps fix the bottle into the board.

Pushing the cut bottle from the outer side of the board, twist the cap from the inner side and tighten in to keep the bottle in place.

And finally, place the Eco-Cooler in the window with the wide part of the bottles facing outside.

Hot air will rush into each bottle, which is pushed to the rim where it starts to expand – this expansion is what cools the air before it enters the room
