This black magnetic fluid makes strange spikes when you bring a magnet near.

  • what would be cool is to connect a series of electromagnets in a bath of ferrofluid to a speaker system (I.E. 3 magnets, bass, treble, and a mix of both, and the bass is a huge magnet, and the get smaller as higher notes) and then to wire it up so that they would magnetize as the inputs are higher, and then play music through it, so it would be a visual music thingy.

  • Ferrofluid is not that different to water. You can't modulate movement at audio frequency. You can at perhaps 1-2 Hz but not 1 kHz because with any degree of excursion you will get splash and a lot of mess. You could audio modulate to volume though.

  • It looks drinkable...Drink it!Die a winner!

  • It is based on mineral oil which is a horse laxative so you won't die. You will have black lips and diarrhea for a couple of days.

  • Doesn't it get stuck if you touch it?

  • Its just like any other dirty black oil.

  • this idea was wonderful in concept.

    and then the music happened

  • someone should make a machiene that brings a magnet closer and farther from the fluid to the tune of music

  • Magneto would have a ball with this stuff...

  • BUT!.... WILL IT BLEND?

  • Good vid ! More Tesla tech in "Wonderful electric lightinn" bu HorizonDelta ;-)

  • @Tesladownunder thats kinda what he said though since hes suggesting hooking up electromagnetism intensity to speaker output.

  • @pomeroy600287 I agree with Tesladownunder's statement about it making a mess if you tried to do that....HOWEVER....if you had the Ferrofluid immersed in another liquid (I've seen this done lots of times before....you'll have to google around to find out what is used, and how they do it exactly) a kind of clear oily liquid...then it should keep the spashing down.

  • I don't suppose this stuff is safe to touch/easy to make? I know it's just oil and iron fragments but what's the soapy stuff that makes it cling together called? I just discovered this stuff tonight and I'm utterly enthralled by it.

  • @Tesladownunder not with audio with the magnetic pulses of the magnet on the speaker.

  • Yeah, I was meaning with volume, but it each could be tuned to a frequency, so it's not the overall volume of the music, just certain parts.
