Focus the Sun's rays economically!
Hand any science teacher a parabolic mirror, and the first thing they want to do is start a fire. (Trust us. We've met thousands.) Get right to the point with this mirror, originally designed for the hikers and campers! It's equipped with a prong that holds fuel right at the focal point. Held in bright sun, it generates smoke in seconds! But don't stop with ordinary paper fuel. Try our favorite demo - the mini-marshmallow roast.
