Deep black with subtle green sparkles, this slightly stiffer Thinking Putty has a mind of its own. Near a powerful magnet it comes alive! Strong enough to defy gravity. It can even lift tacks and paperclips on its own after charging in a magnetic field. Youll be mesmerized by the invisible forces at play. Made in the USA. Each tin is packed with 3.2 ounces of Thinking Putty, an oversized adult handful! Ages 3 years & up.
