Deep black with subtle green sparkles, this newly updated Thinking Putty is softer and more fun than before and 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. You'll be mesmerized by the invisible forces at play. All Crazy Aaron's Thinking Putty is stretchy, squishy, and bouncy. It is truly the toy for everyone - kids, teens, and adults! Putty is the ultimate fidget toy, keeping your hands busy so your brain can focus at work and at school. The sensory applications are phenomenal for both neurodevelopment and soothing those on the autism spectrum. Thinking Putty is non-toxic, latex-free, gluten-free, wheat-free, and phthalate-free. It never dries out and is easy to remove from most fabrics. Crazy Aaron manufactures 100% of his products in the USA and is a leading employer of special needs individuals in his community.
