'It looks like a totally normal liquid, but when in the vicinity of magnets, this black "Oil forms" Bizarre peaks and nearly unbelievable, almost living shapes.This is thanks to the very finest iron particles approximately 10 nanometer (1 Nm = 10 ^ -9) with a protective layer, meaning these won't clump and have extreme reactions to magnetic fields. Great for science teaching in schools, presentations, or experiments at home * 1 Bottle of approx. 60 ml ferrofluid * ferrofluid can always be reused * Please note: Ferrofluid leaves stains on skin, clothing or surfaces, therefore before use to it protects clothing, goggles, gloves, covers, etc. should be (not included) Tip: The stronger the magnetic field, the denser and pointer the shape. The more ferrofluid, and the larger the magnet, the more incredible the shapes... use Please follow the instructions: Ferrofluid has similar pollutant properties to engine oil and may stain clothing that will no longer to remove are locked up safe and sound. It is therefore recommended to always wear protective clothing and goggles during use. The skin must also be protected, because stubborn stains can also be left here. Gloves and goggles are therefore recommended when handling ferrofluid. This protective equipment is not included and must be arranged for before use.
