Solar Cooker Project

Recently, we have been building solar cookers in our science class. We are trying to find a way to make a successful cooker that could be used in other countries that don't have the luxury of ovens. Along with building them, we encountered many challenges. My group was going to build a different type of cooker in the beginning until we couldn't figure out how to construct it. It wasn't folding how it was supposed to in the instructions. Instead, we turned it into a simpler cooker. We turned it into a panel cooker. There is a piece of cardboard covered in foil on the bottom then another one standing up folded a little bit inwards on both sides. It is going to cook effectively because the sun hits all sides of the foil and reflects a lot of light onto the food. Down below is a picture of what it looks like.
