Gannon Posted October 3, 2022 Share Posted October 3, 2022 Flumpweesel had the idea under a post about the recent Hurricane and preparation that a wind-up bath toy could be used for surface agitation in an emergency. Maybe I'm being very dumb and ignorant about something here, but it seems to me that a wind-up wavemaker of some kind could be a very useful product for some with small aquariums and a smaller hobby that doesn't justify buying a generator. A battery bank and USB air-pump is almost certainly more practical though, but I just thought it was an interesting idea, thoug certainly only useful in niche scenarios.
