An amazing visual and interactive toy. Nano scale magentic particles, Ferrofluid, are suspended in a transparent liquid and becomes highly magnetized in the presence of a magnetic field.
An effect from outer space. Using the the incuded magnets to move the Ferrofluid around the bottle, you observe the unique behaviour of this special substance.
Be amazed as the black liquid shifts, dances and morphs whilst creating unique shapres and patterns. An addictive and intriguing desktop accessory.
