Solar Cooker, The End.

There were some very important things I learned from making a solar cooker. You need it to be a dark surface (black works best). You also need something reflective such as mirrors and tin foil. You need a insulator if you want the heat to be trapped in and not escape. If you are going to build a solar cooker use your time wisely. Have the right materials and make sure it reaches  agood temperature. Have  a plan on what youre going to build. I learned that if your going to build a box cooker you need pannels. You should have foil or mirrors or something reflective on the pannels to angle it into the box. 

Which Solar Cooker is the best?

I think that the best solar cooker is this one that is shaped like a funnel. I found a solar cooker that was in the shape of a funnel. It had 3 metal sides and it has a round middle so you can put a pan in it. The materials need are, cardboard boxes, aluminum foil,glue, and scissors/knives. The light reflects off of each of the 3 sides with one opening. There is a metal disk at the botom and it gets really hot and you put the food on there. The durability is good on this. It cooks fast and you can cook all different types of things. It can also be used as a refrigerator.
