Parabolic mirrors: Light bulb ignites a match. Two metal parabolic mirrors are exactly aligned facing each other. A 500W bulb is set at the focus of one mirror and a match at the other. As the variac is turned up, the match will begin to smoke, and in about 30 seconds, bursts into flames. (Same apparatus as C+65+2)
