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

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.

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.

This is a great product! I use it in my sensory bottles, and people love it. It can be a bit messy, so you need to be careful when handling it, and it can be difficult to clean up. However, I believe it's worth it. I have purchased several bottles so far and plan to continue buying more.

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.

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.

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.

This is awesome for teaching kids about magnetism in a fun way. For all ages the effects of Ferrofluid is wowing but for older kids the explanation of how it actually was created and how it works is also really cool. For the price, the fun and learning can't be beat.

Only comes with half the stuff in the description.

リールの防水に使いましたが、量が多く安心して注油できました。

Good

Nice

こんなにたくさん要りません。少量で安く買えたらいいと思います。マグシールドを分解したらメーカーの保証は受けられませんので自己責任で。

It was very good but I can't find my order's shipping date
