Playing with cellphone vibrators

Here are some rhythmic experiments with the tiny motors used in cellphone vibrators.  They bounce if you hold them just right.  They're fun, but everything really depends on the quality of the material you're using it against.

In one scene I'm running way too much voltage through a cellphone vibrator. At one point, it broke... not from too much power, but from bouncing so hard the cable snapped.

There's some pretty cool musical things you can do with these... plus they cost like 89 cents.
