Stretch your imagination with Silly Putty ‒ the crazy compound that bounces, molds, stretches, snaps, and more! With its fun ability to act as both a solid and a liquid, Silly Putty encourages kids to experiment and challenges their imaginations. Roll it into a ball and watch it bounce, stretch it out to its limits, snap it into pieces, or mold it into various shapes. With a little egg of our stretchy goo in your hand, you can count on hours of fun alone or with friends. Silly Putty Glow is the original stretchy formula that glows in the dark!
