SPIKE ferrofluid display (Blue ferrofluid)

This SPIKE contains a blue/purple metallic color-shifting 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. Blue/Purple color shifting ferrofluid! 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 interactio
