Applied Magnets Ferrotec Ferrofluid 4 oz 120 ml bottle Great for Sc

This is an awesome gift for anyone who enjoys science. I bought this for an experiment which it worked perfectly for, but I have ended up using the extra just to play with. It is incredibly interesting, and educational. All you need is a strong neodymium magnet, and a clear container to put it in. The only issue/problem that I have with it applies to any Ferrofluid, & that is that it is incredibly messy, so you need to either keep it contained, or put down some newspaper, and wear rubber gloves when using it. all things considered, the size of the bottle you get for the price & the overall fun and educational Experience Make it well worth the price.

very good

Tons of fun and a good solution for projects.

Cool stuff but make sure you're covered in case you splash some out of the jar

The ferrofluid works great, exactly what I wanted. The only problem I had was that the bottle had a very narrow neck, which means that I have to either get a funnel to put it back or use a jar with a larger lid. Came in one piece and in a reasonable amount of time. I intend to use this to demonstrate magnetic fields with a neodymium magnet
