I don’t how missed this, with kids allergic to bites, this might come in handy.

Airpump, why doesn’t he just use a speaker with a low frequency directly coupled to the fluid.

Perhaps a transparent ball with a solar panel at the top and the speaker with electronics at the bottom (so that it floats upright) with the associated timers.

Does anyone have any ideas for improvements?

If I can find a ball I think I will try this one.
