CMS MAGNETICS - (1oz Kit) Ferrofluid Science Experiment Kit for Education in Magnetism - Includes: 1 Fluid Ounce (29.5mL) Bottle of Ferrofluid, Gloves, Pipette, Petri Dishes

this stuff is nuts. it makes you believe in magic. warning, this can be messy. multiple regular n-s pole permanent magnets snap together at a certain distance and the ferrofluid can splatter. fair warning, but it's worth it. use 1 magnet at a time.

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.

OK folks...in case you're not aware, ferrofluids are messy by nature! Do not use this stuff (any type or manufacturer of ferrofluid) around anything you do not want to get stained, or take precautions like we did and cover the counter or other surface with plastic before using. My son did his science project on ferroluid interacting with a neodymium magnet...it was a great project but the feerofluid is a messy - thanksfully I had read other user reviews on this stuff as was prepared! This is a good quantity of ferrofluid for a good price compared to all the other types and brands of ferrofluid on amazon, as I did the research. Ferrofluid is really cool stuff...the spikes it produces when reacting to a solid magnet are really cool! Ferrofluid is basically a liquid maagnet. Have fun but prepare in advance.

fun stuff tried to make saltwater glass jar for this worked ok. ill try again. this stuff is tricky to work with. do research before work with project.

Zero Stars, one star only because you have to select one.Don't waste your money.This is no more a ferro-fluid than I am the Pope.It acts like used motor oil.I am returning it.The Magnets you see here a 1-1/2" X 2", very powerfulThe fluid was placed in a vacuum-sealed bag and then sealed.As you can see, the fluid is not attracted at all, and does not create any magnetic field pattern.

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.

Perfect for what I needed it for! I was looking for a macro shot of it and it worked out beautifully. Note: I did not use the Petri dish that came with the kit (I had some larger glass ones) nor did I use the magnets that came with it (I had stronger ones available).

What a mess but my fault thought I was being careful but not careful enough
