CMS Magnetics® Magnetic Ferrofluid for Fun! 2 OZ. Packed with Gloves, Petri Dish and Dropper

Good

2oz is actually quite a bit. Good stuff, reacts with magnets and may be good for injecting into the bum of a security guard to free your human magnet friend. I'd say don't actually get this on anything, as it really stains the crap out of your hands/clothes/cat. For extra fun suspend it in about a 70/30 rubbing alcohol/distilled water solution. If you suspend it in 100 alcohol, it separates from the oil suspension and becomes these little black chunks that will be like the worst paint you've ever gotten on your hands. I made the mistake of dumping it in my white bathroom sink and then touched the chunk. It promptly stuck to my fingers and turned them black. I then tried to wipe it out of the sink which was wrong and it spread like a strange paint. Needless to say, the only thing that got this off my hands and sink was more rubbing alcohol and determined rubbing (heh). Get some bottles and make some 'Dwarfs in a bottle' and wow your anime friends with your amazing living Dwarf. Just no soul sucking.

Quality of the product is very good

Not suitable for kids. Be careful as it is very volatile and can spill out very quickly anywhere and could cause a mess

Great flow and magnetic properties to this fluid! I tried making my own for some projects and it did not go too well. This stuff works great! No issues at all.
