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. One would be mesmerized by the invisible forces at play.

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.

Thinking Putty is high quality silicone bouncing putty enhanced with knock-your-socks-off colors. It is all Made in the USA, non-toxic, and never dries out. The three new Super Illusions are unbelievably vibrant colors that shift depending on how the light hits them. The dynamic colors shine like no others: when held up to the light and pulled thin, the colors magically disappear and kids can see right through them. Launch date: June 2012.
