How you can Construct Solar Ovens With Children
Utilizing solar energy for cooking is easy and simple. Solar energy is gathered from a sizable region and concentrated by reflection right into a smaller sized region. The focal stage might attain temperatures of 350 degrees Fahrenheit or even more, sufficient for many cooking.
Trouble: Reasonably Simple
Issues You will need
Durable cardboard box (a minimum of eighteen inches by 24 inches with partitions a minimum of twelve inches substantial)
