Anyone have plans how to make a tipping metal bucket for a water fountain.
Where the bucket fills then spills into a lower body of water then rights
itself and does it all over again ? Jim


Well, you just sort of set it up so that the center of mass is below the
pivot points when it is empty and above the pivot points when it is
full - then it goes unstable, tips to dump the water then is stable again
in the upright position.
