Can anyone give me a VERY simple plan for a solar cooker that could roast a marshmallow? I can only use a piece of tinfoil that is 30cm X 100cm.u can use an umbrellacover the inside of the umbrella with the tin foil and place your umbrella in the sun and focus the sunlight on the marshmallow.Other related question
