Grant Thompson, who posts great science projects on Youtube, created a lens that can focus sunlight like a magnifying glass out of an old tv. The beam the glass creates reaches a scorching 2,000 degrees Fahrenheit that is hot enough to melt metal and burn things he probably shouldn't. But he does. In a new video, he basically just tapes himself burning a lot of things like eggs, wood, pennies, a stack of pennies, and a bottle filled with water. We love his dry delivery in talking about all of the childish things he's doing with the beam in the video below.
