I had never seen nor heard of this stuff. Ferrofluid, where have you been all my life. If there is an alien from outer- space on earth, this is truly out of this world crazy.
I discovered Ferrofluid while fixing a blown Peavey RX 22 Speaker. A diaphragm Kit was purchased and a strange little bottle came with it. Ferrofluid is what the directions said. It went into a small magnetic gap that would help seal the diaphragm to the speaker. Ok, no problem, pull the lid off and pour the stuff in the gap.
But we couldn’t get the lid off. So, a little investigation on the internet and others had the same issue. We started asking our selves, “What is Ferrofluid?” That question has opened my mind to a “Whole New World.”
Once again we went the internet. There are many videos of experts and would be scientist messing with this stuff. why have I not heard of Ferrofluid? I wonder if I was a sleep during that chemistry class, or didn’t read that chapter. Check out the videos below, this is crazy.
I can’t wait to get some.
Only a small amount came in the Fix Kit. Maybe .5 ml. I finally just gave the lid a couple of strong twisst and popped it off the bottle. We poured it into the gap, but nothing came out. Both of us watched, and there was nothing. Turning the bottle over and tapping the bottom didn’t help.
But wait! The stuff was in the crack. ??? It had somehow been sucked out of the bottle and into the gap faster than we could see. Crazy Fast!
Maybe for my birthday I can get a bottle and perform my own alien experiments.
This stuff, Ferrofluid, has been around since 1963. The year I was born. A guy, probably a scientist, Steve Papell working for NASA invented it. Liquid rocket fuel needed to be drawn to a fuel pump in the weightlessness of space by magnets.
