Magnetic Liquid Ferrotec Ferrofluidic Adventure Science Kit EFH1 L_457mm Our Sign Holder with MetalUses for our Magnetic Liquid Ferrofluid: Ferrofluid is a ferrous nano particle liquid that reacts in the vicinity of a magnetic field. Many people will remember seeing this magnetic liquid as part of a science experiment at school. Ferrofluid can be used as an excellent demonstration tool for magnetic experiments. The particles respond to the magnetic field to create a wondrous display of amazing shapes and once the magnetic field is removed the fluid
