In physics class, s'mores were made to calculate the speed of light. They also served as my lunch today. By measuring the distance between the peaks of the marshmallows, it is possible to determine the wavelength of the microwave used to heat them up. By knowing the frequency of the microwave (found on back with serial number), it is actually quite easy to calculate the speed of light. And usually the calculation is off by less than 5%. Pretty yummy, I mean, cool!
