For centuries the speed of light was an enduring, infuriating mystery. Philosophers, physicists and astronomers from Galileo on down studied flickering lanterns, spinning mirrors and distant moons, trying to figure out just how fast light travels. But today you don’t have to go through all that rigmarole. You can find the speed of light in the comfort of your own kitchen.
All you’ll need is a microwave, a ruler and something that melts: chocolate, marshmallows or … stale Peeps.
