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. Review: Use a glass jar! - 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. ## Features - Causes serious eye irritation. - Causes skin irritation. - May be fatal if swallowed and enters airways. - IDEAL FOR SCIENCE & EDUCATION.

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.
