(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 now is, when the watercolor was flowing into the structure, the watercolors do not mix with the ferrofluid. That's because the ferrofluid itself is hydrophobic. That means it doesn't mix with the water. And at the same time, it tries to maintain its position above the magnet, and therefore, it creates those amazing-looking structures of channels and tiny little ponds of colorful water paint. So that was the second project.
Let me now turn to the last project, which involves the national beverage of Scotland. (Laughter)
This image, and also this one, were made using whiskey. Now you might ask yourself, how did he do that? Did he drink half a bottle of whiskey and then draw the hallucination he got from being drunk onto paper? I can assure you I was fully conscious while I was taking those pictures.
