Jerry,

I have used the Pasco mechanical driver, SF-9324< to drive a water balloon.
The balloon was supported by a ring stand roughly about the diameter.
Caution: some resonances look vaguely erotic and may be NSFW ;-)

Dear Tapplers,
Have any of you tried using sound for such things as vibrating a water
balloon or an egg?
How about driving a pendulum?
Would the power requirements be prohibitive?
Would the damping make it not feasible?

Any thoughts?

Thanks,
Jerry H.
