Baggy Solar Cooker

Introduction. The insight for this project came from two community members: Mintyhippo and pepi. Special thanks to them. I became interested in solar cooking a few months ago. Having surfed several solar cooking sites, I decided to make a solar cooker. This one turned out to be rather efficient. It won’t take you long to build it. You may use materials scattered around the household. The cooker can be easily built by a junior school student (with exception of metal work, it should be done by an adult). So you are welcome to give it a try.
