We have covered plenty of solar cookers here in the past. The Der Wiener Roaster happens to be a compact device for cooking hot dogs. Simply place two foil-wrapped hot dogs in the metal tube and the solar cooker will do the rest. It will use the sun’s rays to cook your hot dogs for you. The Der Wiener Roaster is made of high density polyethylene and has a shield over the metal tube for added insulation.
This solar hot dog cooker’s surface has an area of over 250 square inches and measures 22 x 14.5 inches. It is a nice tool to show your students how solar cooking works.
