SPIKE ferrofluid display (Black ferrofluid)

The SPIKE Ferrofluid Display is a mesmerizing interactive kinetic sculpture containing 7ml of ferrofluid. It was designed to showcase ferrofluid's coolest feature, spikes! We designed the SPIKE to generate the largest possible spikes by utilizing 3 neodymium rare earth magnets in combination.

There are 2 positioned in the base, and when you place the handheld magnet on top of the display it combines to create a large magnetic field (which the ferrofluid follows) to create beautiful giant spikes and organic shapes.

• Contains the highest quality ferrofluid synthesized by Ferrotec (won't break down in a few weeks like cheaper competitors)
• Create amazing shapes and giant spikes using the included magnet
• Beautifully constructed and addictive desk toy, you won't be able to put it down!
• The ULTIMATE gift for the inquisitive mind

Add an LED light and extra magnet for more interaction (highly recommended for colored ferrofluids): LED Light and Magnet combo
