An awesome silver color with dark streaks throughout, this slightly stiffer Thinking Putty 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. Comes with one super strong magnet in the tin. When Super Magnetic Thinking Putty is stretched, molded, or shaped, the putty has no magnetic charge and behaves like any other Thinking Putty. However, in the presence of a magnetic field, its magnetic forces begin to align. Suddenly, a truly Super Magnetic Thinking Putty is created that will attract to one magnetic pole and repel from the other. Made in USA! Each metal tin is hand packed with 1/5 lb of Thinking Putty, much more than in a plastic egg! Ages 14+.
