im doing a science project and i need a little help :D
Putting the cookies on a sheet of foil under the sun won't get them hot enough to bakeYou have to set up mirrors around them to get as much light to land on them as possibleAnd to keep the heat from drifting off the cookies you need to put them in an oven - basically a metal box painted black to absorb heat from the lightThe solar heat penetrates the metal box and heats the air inside like an oven, so the temperature will go upAll these reflectors can be made of aluminum foil glued or taped to cardboard and cut to fit each other in a reflector arrayIf you made the array in a large dish - shaped like a satellite dish, you can get a lot of light but it's hard to make a large array stand up on its ownIt's better to try a rectangular array.
