If you just celebrated Easter, you might have some stale marshmallow Peeps lying around the house. And if you want to avoid eating those Peeps, they are the perfect material for a science experiment you can do in your own kitchen.
With the help of a ruler and a microwave, you can use leftover Peeps to calculate one of the constants of the universe — the speed of light.
It might sound crazy, but all will be revealed in this video from NPR's science YouTube channel, Skunk Bear. As a bonus, you'll also get to see animated Peeps illustrate the history of the search for the speed of light going back to Galileo.
