Comment on speedometers

Hmmm, he says, reveling in his pedantry: Speedometers actually measure net displacement, and since thermal energy causes collisions on the small scale, but results in very little net movement for the particles, its not quite like a speedometer.
I like to think of it as a ball pit with one of those super bounce ball stacks in it.
