Title:Psychedelic science
Short URL:
Summary:(Laughter) any phrase to play the video at that point. Ferrofluid has a very strange behavior. It's a liquid that is completely black. It's got an oily consistency. And it's got tiny little particles of metal in it, which makes it magnetic. So if I now put this liquid into a magnetic field, it would change its appearance. Now I've got a live demonstration over here to show this to you. So I've got a camera pointing down at this plate, and underneath that plate, there is a magnet. Now I'm going to add some of that ferrofluid to that magnet. Let's just slightly move it to the right and maybe focus it a little bit more. Excellent. So what you can see now is that the ferrofluid has formed spikes. This is due to the attraction and the repulsion of the individual particles inside the liquid. Now this looks already quite interesting, but let me now add some watercolors to it. Those are just standard watercolors that you would paint with. You wouldn't paint with syringes, but it works just the same. So what happened
