megaGlux Magnetic Black or Silver
This handful of GLUX has the standard mind blowing Non-Newtonian fluid stuff of being a liquid and solid at the same time. But, when you charge this GLUX by realigning its micro bits, it becomes a mighty magnet! Powerful enough to defy gravity, lift paperclips and repel a piece of itself. For ages 14 and up. No one can resist its pull!
