An awesome silver color with dark streaks throughout, this newly improved Thinking Putty is softer and more fun and has a mind of its own. Near a powerful magnet it comes alive more powerfully than ever before! Strong enough to defy gravity, it can even lift tacks and paperclips on its own after charging in a magnetic field. You'll be mesmerized by the invisible forces at play.
