My group and I built a solar oven with a giant magnifying glass. We where going to bake cookies with it but sadly when we tried it it didn't work, I'm not sure why. We used a giant magnifying glass so there were potential that it could blind some one if no wearing protective eye wear. the reason why cooking with a magnifying glass works is because with a magnifying glass, you are concentrating the energy of the sun the area of a lens into a single point. That is sufficient to raise the temperature of a single point high enough for a chemical reaction to occur.
my group and I where really excited about this project and bummed out when it didn't work. We think we didn't do enough research for it and we didn't do something right. We didn't have any trouble with building or anything but when we had to bake the cookies it didn't work. one reason it might of not of worked is because the positioning of the magnifying glass was not right and the point made with the sun rays was not hitting the pot.
It also took us a long time to actually do this experiment, This is mostly because one of us was always absent. Then when we do actually do it it doesn't work. you could imagine our disappointment but it was probably our fault for not researching enough about it.
