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

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!

Outstanding does what it says it does buy it

This stuff is cool but messy if your not carefull! Stains like a SOB! Wear gloves and use something under your work area to keep spills confined!

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.

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.

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.

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 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。

I'm not a chemist, but it seems to be the real deal. If you want to make a display just add one pipette squeeze to a 1:1 ratio of distilled water to isopropyl alcohol. I used 99% isopropyl but I'm told also rubbing alcohol works well.

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。

Christmas gift, shipping was fast arrived in lots of time. Happy with the product.

Great product!!! It looks exactly like the nice videos on youtube
