We tested our mini solar oven to see if it will get hot enough to cook an egg.
Setting up a Do-It-Yourself kind of cooking apparatus can be exciting. This video enumerates the assembly of a mini solar oven and even tests it by cooking an egg. A discarded pimento glass jar is painted with some non toxic black paint and used to cook the egg covered with a slightly bigger glass bowl. The entire set up is placed upon a reflector made from easily available scraps. The egg cooks perfectly sans any supervision and fuel other the sun light.Try it.
