I should have read below before posting, oh well, sorry all

Ive been watching and its agitated by passersby, hmmm, dont understand the mechanism, a wave amplifier of somekind ?

I dont know 100% if this is correct , but long ago, someone said this stuff is agitated by someone near it, or passing by it, it was supposedly a student there, or past student, cant remember.  Understand it was several years ago, maybe if some one looked at the archives here, or talk to such as blue or Viti, perhaps Trader,  i dont know with whom I was talking to when it was said, sorry

Carol, I've no idea but the water is very agitated at the moment.

Does anyone know what this is?
