This handful of GLUX has the standard mind-blowing non-Newtonian fluid stuff of simultaneously being liquid and solid. 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! 45 huge grams! Comes in either magnetic black or magnetic silver colors. Made in the USA.
