One of the most fun and interesting science experiments around. Ferrofluid is a magnetic liquid that takes the shape of any magnetic field applied to it, and changes in density (it gets thicker) in a magnetic field. It's an AMAZING tool for visualizing magnetic fields in three dimensions! With a bottle of ferrofluid and some strong magnets, you'll be set for hours of fun experiments and demonstrations

I wonder if these is a way to freeze the ferrofluid after making it show a magnetic field in 3d. that would be awesome if you could.

You could try to make a mold of it... Then create a sculpture using the mold.

Wow that is impressive. Does it only work with very strong magnets or would it work with natural magnetic fields?

Only for strong magnetic fields...

I have been doing ferrol fluid experiments for the last year and a half now and its a lot of fun and MESSY... Workign on a sculpture array with it.

Is it true that it stains everything it touches?

Would you happen to have a picture of your work with ferrofluids? How would you be able to solidify a ferrofluid? What about practical applications for analyzing magnetic fields, can anyone give some?

Are there any health dangers associated with this?

Looks like so much fun...I'd make a mess for sure. Hehehe, also looks like something the crazy folks on Mythbusters would find a use for ;)

It never truely becomes hard. Its actualy very intresting to feel with your hands when under the pull of a magnetic force. It does in fact fight you but it will give and split in areas you squeez. I will take some pictures when i get back into the studio I was in for surgery over the summer and havnt been back since just been busy at work.

HEalth hazzards well its particals of metal and oil so id imagen drinking it would be bad. defnetly dont think you would want to get the stuff in your eyes... other than that i cant think of any.
