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'm going to become rich and famous after i invent a device that allows you to stab people in the face over the internet

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?

Its oil so yes... Its metal particals with skin bound to it.

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
