Is it possible to send it fast?** A: yes! **Q: I heard what it is rocket fuel made by nasa? it is safe to touch it?** A: It was invented by Nasa, but it's not rocket fuel. It can irritate some skin though, and is very very messy and stains everything so it's best to wear gloves any only handle manipulate it in disposable petri dishes as shown or old pyrex cookware you're not going to use for food again **Q: If i made a line of this and put a magnet at one end, does the other end become magnetised, ir is the effect only localised?** A: Your line would not stay a line. As a fluid, it would be drawn towards the magnet. I believe the fluid contains iron particles, however, which are paramagnetic and so the magnetic field is somewhat extended in its direction. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very cool stuff, mind you don't spill it though! *by on Reviewed in the United Kingdom 10 February 2018* The fluid comes with two small screwtop plastic containers, along with a standard plastic petri dish and pipette. For the best effect I would advise putting a small amount in the petri dish, barely enough to cover the surface, and approach with a magnet from below. Be very careful, as a strong magnet from the side can easily cause the fluid to fly over the edge out of the petri dish!Be extra careful, since the fluid stains most materials, and can be difficult to wash out.The effect from a magnet is very interesting to look at. The volumes required are very small so this amount could be used to amuse quite a few people. ### ⭐⭐⭐⭐ Use a glass jar! *by on Reviewed in the United Kingdom 12 October 2019* OK, top tips: open up the packaging throw away the plastic dishes and the pipette. Get your self a small, glass jar with a tight screw on lid, like an old small chutney jar and pour in the fluid, let it drain, wrap up the old packaging and throw it all away. Seal the jar with the lid.Now you can safely play with a magnet on the outside of the glass jar and you won't get this everywhere (like I did!). Its a good laugh and amazed our granddaughter and others. ### ⭐⭐⭐⭐⭐ Great but messy *by on Reviewed in the United Kingdom 30 December 2023* Bought this for my science keen 7 year old. He loves it! But it DEFINITELY needs supervision, it's messy!! I learned that the hard way.. ## Frequently Bought Together - EFH1 Ferrofluid 20ml for Science, Education, Experiments, Students, and Teachers - Iron Filings for Science, Education, Experiments, Students, and Teachers - 80g - 2 Educational Alnico Bar Magnet for Science, Education, Experiments, Students, and Teachers - North & South Identified - 11mm x 6mm x 75mm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/48788274-efh1-ferrofluid-20ml-for-science-education-experiments-students-and-teachers](https://www.desertcart.ro/products/48788274-efh1-ferrofluid-20ml-for-science-education-experiments-students-and-teachers) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-23*
