    You forgot the most important test: Having the curly hair guy lick it

    There could have been small pockets of air trapped on the surface, resulting in a larger volume measurement, in turn contributing to a lower density calculation. But it looks like less than 10% error from expected value, which is really good for a home setup.

    Glad to see finally a real scientific instrument being used on one of Cody's experiments. Mitchell (Waterjet Channel) Tongue.

    if it looks like a diamond, smells like a diamond, and tastes like a diamond, it's probably a diamond.
