Measure the Speed of Light with Chocolate and a Microwave!

Did you know that you can measure the speed of light with a chocolate bar and a microwave?

It's quantum mechanics, in your very own kitchen.

Here’s a really cool intersection of food and science that deserves attention: did you know that you can measure the speed of light using chocolate, a microwave, and a ruler?

All these humble instruments can come together to help you conduct “kitchen quantum mechanics,” as one researcher.

In order to measure the speed of light in your microwave, you’ll need to stop the plate inside from moving, so remove the wheels. Next, lay your chocolate flat in the microwave and set on high for 15 seconds.

By measure the distance between the melted and soft portions of chocolate on the bar you’ll find the wavelength, which you’ll multiply by the frequency (waves per second) of your microwave. Yes, it is more complicated, but I’ll leave the explanations to the team at the Bristol Science Center.
