	If you have a helium balloon in the car with you (and your fuzzy
dice), you will see something really strange: the balloon will lean in the
opposite direction the dice do.  The explanation I've always heard for this
is that the balloon's motion is dominated by buoyant forces; when the air
in the car feels a centrifugal force and goes one way, the balloon goes
the other way.
