Not content with plain old pink putty, Aaron started making vibrant colors and coming up with his own special additives—like hypercolors that change color when you warm the putty with your hands. When demand for his custom putty started catching on, Aaron walked away from his career as a software engineer to make putty in his mother’s basement. Sound a little crazy? Aaron’s coworkers thought so and dubbed him “crazy Aaron.” The name stuck, and Crazy Aaron’s Thinking Putty was born. Today it’s produced in a workshop outside of Philadelphia, where 90 people with special needs manufacture, package, and ship the putty to more than 30 countries worldwide.
Thinking Putty comes in a slew of wild colors and flavors, including glow-in-the-dark putty, heat-sensitive putty, and electric-colored putty. It can stretch like rubber and bounce like a ball, and because it’s silicone-based, it won’t dry out or crumble over time. It’s part toy, part stress reliever, part physical therapy, and entirely addictive. Be prepared to never want to let it go!
