Putty is great for engaging the imagination & refreshing the mind. The soothing kneading of elastic, vibrant putty channels fidget energy so you can focus mentally. Putty is ideal for networking your right & left brain, promoting free flow of ideas, and enhancing relaxation. The glow in the dark putty is a powerful, tangible motivator - encouraging creativity, flexibility, innovation, good humor, and stress relief. Plus, the cool glow in the dark feature makes kids love playing with the putty! Foxfire is a shimmery glitter Thinking Putty that reveals its true colors with the included blacklight keychain (in the tin). In a flash, mint green becomes dark blue with an eerie glowing edge. In the dark it glows brightly for over 12 hours. Best played with under regular room lighting so you can see both the daytime and nighttime colors simultaneously! Hold the blacklight keychain close to the putty to draw a dark line, and move it farther away for a blurry line. What can you do with Phantoms Thinking Putty? The possibilities are endless!
