Students will love cooking their lunch using the unlimited supply of solar energy! No electricity, no flames, and best of all, no pollution. The Solar Oven's reflective panels concentrate the Sun's light into the cooking chamber at the base. The chamber's transparent ceiling allows the sunlight to pass through, but keeps the heat energy trapped inside just like a greenhouse. The chamber can reach temperatures over 170¼C. Use it to cook food such as hot dogs, hamburgers or soup in less than 10 minutes on a sunny day, even in the middle of winter. Reflective panels fold down into a conveniently sized box for easy storage. Food cooks inside a plastic bag so there is no mess to clean up. Cooking chamber is 9" x 9". Complete instruction guidebook is included.
