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

Outstanding does what it says it does buy it

Extremely good ferrofluid. Excellent spike formation around the field lines of a magnet. Be careful as the stuff can be a massive mess 😬. Easily cleaned with soap and water, but highly recommend extracting only small amounts at a time, and always keeping the pipette tilted facing upwards when not in use. Great stuff!

I’m really impressed with this CMS Magnetics Ferrofluid Science Experiment Kit. The ferrofluid itself is high quality with very fine particles, and it reacts beautifully to magnets. Everything in the kit—gloves, pipette, petri dishes—made the experiment clean and easy to set up. It works exactly as expected and feels like a well‑made, reliable product. Great for learning, teaching, or just having fun with magnetism.

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.

DO NOT BUY! I made a huge mistake with this brand, just pay an extra 10 bucks for a reputable company. This fluid will come majorly oxidized and clumpy and has lost all the properties you are looking for.

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 stuff is pretty messy if you’re not careful. It’s essentially iron shavings contained in used car oil. Seriously it smells and looks like used motor oil. I almost gave this a 1 star review had not for my son found a strong enough magnet to make the spikes appear. So be sure to have a quality heavy duty magnet handy.

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.

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。

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。
