Cytotoxic writes "What to do with all of those leftover Valentine's Day chocolates? — a common problem for the Slashdot crowd. The folks over at Wired magazine have an answer for you in a nice article showing how to measure the speed of light with a microwave and some chocolate. A simple yet surprisingly accurate method that can be used to introduce the scientific method to children and others in need of a scientific education."
you can use chocolate to measure speed of light (Score:5, Funny)
although its far more interesting to use chocolate to measure the speed of digestion

It's approximately 300 000 km/h. 'Nuff said.

Or even, what's this thing called "leftover chocolate?"

This experiment has lots of problems. *nom nom nom* First, microwave ovens don't always precisely match the given frequency. *chomp chomp* Second, and more importantly -- *chew chew swallow* -- identifying the hotspots and measuring the distance between them is difficult and error prone. *nom nom* And that's even when the chocolate is fresh! It's worse after it's already been partially melted. *stuff face* So I had to perform many experiments, using fresh chocolate each time, to get an accurate measurement.
In conclusion, this experiment rules. *nom nom nom nom*

If a microwave, chocolate, and performing an experiment make you horny...
Let's just hope you never learn what fondue is.

Now this is very informative ;-)
Actually, not that much since you did not specify in which environment it has that "exact speed". Saying the speed of light is 194792442 m/s or any value is just as precise.
Now, saying that c is constant equal to 299792458 m/s is absolutely correct although, the speed of light is actually:
c/n where n is the refraction index.
In a microwave oven at sea level, the speed of light is *approximately* 299792458/1.0003 = 299702547 m/s

Bu bu but... That's the secret ingredient in auntie Curie's "soul warming" chicken casserole!
It warms you up inside, helps you lose weight, AND makes you the brightest one at school, all at once!
