How many of us when we were 12 used a magnifying glass to focus the sun’s rays on something just to see it smolder? Grass, ants, paper, you name it. I suspect that most of you reading this did something similar in your youth. Well somebody has taken it a bit further by building a homemade Solar Death Ray.
The Solar Death Ray is made of 112 mirrors mounted on a platform 4 feet wide and 6 feet tall. Each mirror is a square roughly 3.5 inches on edge. All these mirrors focus the sun to a single spot 5 feet, 6 inches from the mirror platform. A wooden fork extends from the mirror base to the area near the focus and serves as a mounting point for Solar Death Ray targets.
