Magnetic Liquid Ferrofluid (30mL) + Cylinder Magnets 10mm x 10mm (2pcs) H_22mm This pack of magnetic buttonsFerrofluid is a ferrous nano particle liquid that reacts in the presence of a magnetic field. Ferrofluid is used as an excellent demonstration tool for magnetic experiments and recently it is being used in modern art and for other creative purposes. When the fluid is exposed to magnetic field the particles align magnetically with north and south poles and display amazing shapes, once the magnetic field is removed the fluid returns to its random
