You’ve probably seen kids burning things with the use of a magnifying glass. How does it work exactly? It works because photons, the elementary particle which carries light from the sun to the earth, also contain heat energy. A magnifying glass can can make the path of these photons narrow and cause so much heat to be concentrated at whatever it’s focused at. Of course, a magnifying glass isn’t the only thing that you can use to make fire using sunlight – you can also use a light bulb! Make fire using a light bulb – learn how to do it by watching the activity video.
