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

I tried every kind of suspension liquid to make this ferrofluid work for displays that my son and I wanted to give his friends. We tried mineral oil, vegetable, and vegetable with a little water. Don’t buy if you are wanting to make displays it won’t work. Also it is not very magnetic a lot of the “ferrofluid” will be left behind when trying to get it to move through the suspension fluid clouding up the entire solution leaving you with a jar of solid blackness and no visibility. I don’t know what this is probably some iron shavings, water based food coloring, and oil is my guess.
