A fool chases rainbows; a sage grabs a hold of sparkling Rainbow Thinking Putty. Like other Crazy Aaron's Thinking Putty, this kinetic plaything can support concentration, bust stress, and help you have fun! Hold it up to the light to see a shimmer of sparkling glitter reflect in a rainbow of colors. Rip it, tear it, bounce it, and stretch it over and over again, each time observing the beautiful multi-colored sparkles suspended in the clear putty. As you continue to play with it, Rainbow Thinking Putty will at first appear clear (like thick glass) and gradually become more opaque, but the shimmery multi-colored glitter will continue to sparkle. Set it down for a while (if you can manage), and Rainbow Thinking Putty will return to its original crystal-clear appearance, ready for you to play with it once more.
