This summer has been nice and warm with lots of great sunshine - a great opportunity to do a little "summer school" and build a solar oven. The kids are always asking how hot it is outside and I always say "hot enough to fry an egg" which they then give me a silly (yeah sure mom) look. So after doing a little googling and finding some great instructions and recipes we went about building our own solar oven. Instead of a pizza box we used a USPS priority box and just used one of the front openings to insert our cookie sheet with peanut butter cookie dough. Don't you just love the pink duct tape! The girls and Drew checked the solar cooker every 10 - 15 minutes to make sure the sunlight was properly reflected into our oven for maximum heat. After awhile (I lost track of the time!!) we brought in the solar oven and using an oven mitt extracted a tray full of solar baked peanut butter cookies! Since we propped up the solar oven in the beginning the cookies kind of ran together but they still tasted great! Here are some pics of our summer science experiment!
