REFILL KIT: Use the included compounds, and your imagination to create five bouncing balls!

Known for creating the best putty in the world, Crazy Aaron has invented PermaPutty®, a mixture of two special putty compounds that allows for permanent molding.  

Crazy Aaron's PermaPutty® is a unique material that transforms from a pliable putty to a permanent bond in just 10 minutes. It's important to mix and mold only one ball at a time to prevent the compound from hardening before it's molded. When you're ready, mix the glitter compound in packet A with the activator compound in packet B. Each A+B combination makes one ball.

  • Includes 5 of each A & B compound packets & Instruction Sheet

Squeeze, stretch and have fun!

There are over 100 varieties of Thinking Putty® with 30 different effects to discover!

Thomas ★★★★★

Mixing the two compounds was surprisingly satisfying, and watching the balls harden into something that actually bounces made me feel like a kid again. The refill kit gave us enough material for five solid creations, and the texture of the PermaPutty itself is smooth and easy to knead.

Eli S. ★★★★★

The five balls came out perfectly bouncy, and the refill kit gives you way more compound than I expected for the price. My kids have been playing with them nonstop since we mixed it up.

George K. ★★★★★

Mixing the two compounds is oddly satisfying, and we got five perfectly round balls out of the kit—the bouncing action is way more springy than I expected. Took about ten minutes to knead each one, but the kids were hooked the whole time.
