Saw that video over at BoingBoing, and at the point where they explain away its inaccuracy by saying all popcorn kernels are different in size and weight, I thought to myself, "Well why couldn't you weigh each kernel just before it gets loaded into the breech? I mean, come on, if you did all the other engineering, you should be able to include a scale also."
And then I realized how much like a nerd that made me sound.
