Dancing water or fluid dynamics

Prompted by the housekeeping of the last post to have another go at the dancing water bowl, the first time for a year or two.

I didn't bother to read my notes, for example those at references 1 and 2 beforehand, but I did remember about the water being best luke warm. While I did not remember that the water should be as shown, up to the cusp of the second chevron down. That took trial and error.

As did the pad to stand the thing on. After trying all the permutations, small paving slab then roof tile wrapped in a bit of cloth seemed to work best. Something, maybe, to amplify the vibrations rather then to damp them down. Contrariwise, it seemed to work better with the cloth than without.

After about twenty minutes, I was getting the water up fairly respectably, with the dancing spreading out from the chevrons but not yet covering the whole surface and not yet making it to the six inches reported previously. Maybe that will come. Maybe BH will do better, being better generally than I at matters music & movement.

PS: the Chinese lady who sold me the bowl could get the water up with far less messing about, at least in a rather smaller bowl. The spirit was clearly with her.

Reference 3: Bing knows all about 'dancing water bowls', but with this offering being slightly different. Bit more bubbles as we would have said in the late 1960's. https://www.youtube.com/watch?v=OFPD94zrbkY.
