    ...don't try this at home. Theobroma cacao (chocolate) is a highly dangerous substance with known stimulant effects. It is also highly addictive and should be used with extreme caution. Overdose can cause morbid obesity, sluggishness, and death. Only qualified experts should handle this dangerous reagent at home.

    I am experienced at handling this most hazardous material. Please wrap it carefully in a heatproof container, and mail it to me. It will be disposed of properly. (burp)

      Yeah, well the guy put some dihydrogen monoxide (DHMO) into his microwave as well, so we know that he has no concern for his own safety or those around him!

    There is a very interesting article on About.com that shows how to measure the speed of light using your microwave to melt chocholate.

    Big deal...I can measure Hubble's Constant by charring bagels in my toaster. Pffft.

    No, you thought wrong.
    Speed of light approx 300 000 km/s = 3E8 m/s.

    Actually, the easiest way to measure the speed of light is to measure the interval between the lights turning green and the first cab horn sounding during the morning rush hour in Manhattan, then measure the distance from the lights to the cab.

    Neither original nor practical, but then I am tired and this is /.

    Bah, that's easy stuff. It's about time that About.com tackled the real holy grail of science - how to teach Slashdot editors to use a spelling checker.

      You are wrong by 207 542 m/s which is quite a large margin for keeping the Slashdot correction nazis at bay.

      On behalf of the Guild of Pedants and Correctors, I hereby state that a 0.0692% error is well within the acceptable error for most Slashdot posts.

      Quite frankly, we're usually happy if you people get within an order of magnitude of the correct value.

  7. Using Ping to measure speed of light by AYeomans · · Score: 4, Funny

    You can always use your network cables instead; brief description or full paper.

    Anyone care to use the method with RFC1149 Avian Carrier Protocol, namely Using Ping to determine Speed of Flight!

    There was this episode of Mystery Science Theater 3000 (Secret Agent Super Dragon?) where the main character flips a light switch, and about half a second later the light dimmed down. Crow said "Light travels slower in his world". Heh.

    Hmmm.. sorry guys, it really is more of a visual joke.

  9. Ants by BuilderBob · · Score: 5, Funny

    You can also measure the speed of light using ants, the ants are small enough that they can fit into the low energy points of the microwave.

    If you put some ants in the microwave, and switch it on, they all start moving from the heat into the cold spots, measure the distance between the cold spots and you have the wavelength.

    Obviously, you shouldn't *actually* try this, unless the ants happen to climb in there looking for food, then they're fair game :) And take the turntable out, that's cruel.

    The calculation (chocolate or ants) does still rely on prior knowledge of the frequency of the microwave(s) being used. Trying to measure the speed of light without a prior fixed frequency or wavelength is much more taxing. A shortwave radio can help though, or a flashlight and a large telescope (bouncing signals off the moon)
