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.

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.

The one-ounce container of ferrofluid is more than enough if your child has a school science project or if you want to have some fun. However, please do not use the included petri dish, as it's too small and the only thing keeping me from giving this product five stars. The ferrofluid will easily migrate out of the included dish and stain anything with which it comes into contact, so wear gloves and goggles.

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).

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.

Just no. Do yourself a favor and use glass, not plastic. This product actually seeps through plastic. It splatters and it doesn't wash off of anything. It's literally impossible to use this kit as is

My 12 year old has seen this on YouTube channels that he follows, as well as something from MythBusters or one of those shows. He HAD to have Ferrofluid and the magnets necessary to play with this stuff. BEWARE- it is messy and should only be used with supervision! My little professor was completely in his element. It comes with the dish and the pipette dropper and gloves. You'll need something to protect your table, and the Neodymium magnets to work with this.

What a mess this stuff makes! The two magnets were shattered inside the package somehow, useless now.
