Nancy,
I could see spiral flows emmiting from the speakers, but don't know the relevance of the bottle in a hole?????
If some basic explanation could be added to what is been achieved etc???
Have been distracted for months with so many dramas , as such, that I have not had any focus on Your efforts or anything really, hopefully things will settle down now, and I can return attention to what I love.
Today is typical where our electric consumer unit RCD has gone wonky, and won't re-set ( have linked past it presently.)
And I am off to buy a complete new unit with up to date earth leakage protectors , I thought becoming a pensioner mean't lots of spare time, it is the opposite.
Hope all is progressing , and wishing You and John hit the solfeggio notes of nature.
Kevin
