How to Make Silly Putty Stronger

Silly Putty is a simple, clay-like children's toy that can stretch, bounce or even be squeezed for stress relief. Packaged in plastic eggs, the toy is available in most toy and department stores, but you can make a generic version by combining white glue with borax. If your Silly Putty -- either the commercial kind or the homemade kind -- is too gooey for your taste, you can add borax to strengthen it.
