“This solar fridge is a simple and quick DIY project.
The reason I decided to build it was because the fridge in your house takes up a ton of energy. This fridge is so cheap and reliable that it can be used in 3rd world countries. It takes about 15 to 30 minutes to complete and it only cost around $15 dollars.

- 1 large clay flower pot
- 1 small clay flower pot
- sand (I used about 1/4 of a bag)
- towel
- water
