Novelty magnets offer practicality, entertainment and great gift ideas. If you have magnetic noticeboard at home or in the office, you can jazz it up with a selection of novelty magnets. When it comes to magnets, Ferrofluid, Magnetic Putty and Feel Flux gadgets are sure to amaze. Who knew magnets could be so fun? Magnets are used by school teachers and experts within experiments and education. They are a fantastic tool to illustrate scientific law and engage students with interactive learning. Review: Very cool stuff, mind you don't spill it though! - 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.

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 A***A on 10 February 2018* The fluid comes with two small screwtop plastic containers, along with a standard plastic petri dish and pipette.

Can play with making shapes in the petri dish or put the ferrofluid in water (videos online) and see what happens then. Loads of opportunities to have fun with physics, just make sure to keep it in the containers as it stains everything. ## 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.sg/products/48788274-efh1-ferrofluid-20ml-for-science-education-experiments-students-and-teachers](https://www.desertcart.sg/products/48788274-efh1-ferrofluid-20ml-for-science-education-experiments-students-and-teachers) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-09*
