My physics teacher showed this to my class today, and I thought it was the coolest thing ever

I love the awesome things that you can do with science~

okay but have you seen this video though

what a great sound

Haha wow my best friend just showed me that exact video, and I just registered for courses for next year ONE OF WHICH IS PHYSICS

THAT. WAS. HELLA. RAD.

*jams out*

I love these!!! And that red hot nickel ball channel is one of my favs.

Any y'all ever heard of ferrofluid, because it is the coolest stuff: https://www.youtube.com/watch?v=WXvar-4M6VA

@Maid0fTime The nickel ball noises, ohmygosh.

@Nishinoya I've never seen anything like this before! Does the fluid create those structures based on the intensity of the magnetic field going through it?

SCIENCE!!!!!!

oh my god the red hot nickel ball videos are so satisfying and i love them. have you seen the one with the giant gummy bear? O:

@Xeneris yeah essentially! The shape itself will usually depend on the size/shape of the magentic field, and gets bigger when the field is stronger. It's a really neat way to illustrate how magnetic fields work, imo.

Ferrofluid is really just iron particles suspended in... oil I think? But it's one of my fav things.

@Verruciformis You mean the one where they put the gummy bear in potassium chlorate? My chemistry teacher actually did it in class last year, it was so cool o:

@Nishinoya Iron particles suspended in oil, that's pretty neat! I think I used to have a bag of iron filings, it was always cool to put magnets near it and see what it did, haha.
