When Muderick first started investigating how putty was made, he learned that its main ingredient was a material called silicone. Silicone is a rubberlike polymer. This substance has large molecules made up of repeating units. The chemical structure of polymers makes them lightweight, durable, and elastic, so they can be stretched and molded into nearly any shape—perfect for putty.
Unfortunately, silicone is expensive. Muderick figured out that to save on costs, companies often added other, cheaper substances to their putty recipes that made the putty dull and dry. Muderick thought he could do better, so he set off in search of new materials that were nontoxic, were relatively inexpensive, could be made in brilliant colors, and would not dry out.
