Heritage & History
Aaron Muderick founded Crazy Aaron's in Norristown, Pennsylvania in 1998, starting with a simple goal: create a silicone putty that was more interesting and engaging than anything already on the market. Muderick's background in materials and his genuine enthusiasm for the sensory experience of putty led him to develop formulations that changed color, glowed in the dark, responded to magnets, and shifted hue with temperature — properties that standard toy companies had not explored with putty as a medium.
Each tin of Thinking Putty is hand-mixed and packed at the Norristown facility, a production method that allows for tight quality control and the kind of small-batch variation that makes each variety genuinely distinctive. The company has introduced hundreds of varieties since 1998, from the original basic colors to specialty lines that use thermochromic pigments, magnetic iron particles, and photoluminescent materials.
Made in Norristown, Pennsylvania
Crazy Aaron's manufactures all of its Thinking Putty in Norristown, Pennsylvania, a borough in Montgomery County just northwest of Philadelphia. The hand-mixing process is not a marketing affectation — the nature of silicone putty production and the variety of specialty ingredients used in different formulations makes small-batch hand preparation the most practical and quality-consistent method. Workers at the Norristown facility mix, pour, and tin each variety according to proprietary formulations developed by Muderick.
Thinking Putty is non-toxic and never dries out, properties that make it suitable for all ages and durable enough to last for years with normal use. The product's American manufacturing, combined with its domestic employment model and Muderick's continued hands-on involvement, has made Crazy Aaron's one of the more compelling stories in the modern American toy industry — a small Pennsylvania company that created an entirely new product category.
