SLOW MOTION SCIENCE!  Ferrofluid dropping on magnet

Love your video, yet one fact: black holes don't exist... See www.kryon.com/free audio or their online thesaurus. 
On another note: crop circles are produced by magnetic ( and possibly other) forces from inside the Earth. It looks like a visualization of that. 
My friends asked me 15 years ago about one partucular spectecular crop circle produced overnight in UK. I said this: you look down on it thinking outer space.  I look up from underneath it and see Earth Herself producing it.
Have a nice day.
