Introduction
Silly Putty is a moldable silicone-based substance, sold chiefly as a toy, with remarkable properties of stretching and bouncing. It stretches like taffy, yet breaks into pieces if pulled too sharply. You can form it into shapes, like Play-Doh or you can roll it into a ball and it bounces! Silly Putty has not effected my life in anyway, other than entertaining me when I’m bored. I chose Silly Putty for my project because every child at some point in their life plays with Silly Putty. The strange substance always was so peculiar to me that I was curious to see how it worked. I picked Silly Putty so I could finally understand what made it behave like it does and how Chemistry was involved in creating it.

How is it made?
Silly putty was made by mistake. During the World War Two the united states was trying to create a substitute form of rubber and Silly Putty was created. Silly Putty is made by putting boric acid with silicon oil. When combined the substance turns into a gooey bouncy material.
Where is it made?
Silly Putty has been a popular toy in the world since 1955. In 1977 it became product of Crayola and has been made in those factories everyday. A sigma blade mixer is what Crayola uses to manufacture Silly Putty. Boric Acid and Silicon Oil are placed into the mixing bowl and blended for a half and hour. After this the machine tips the silly putty onto a cart where it is cut and packaged.
How does it work?
Silly Putty has several unique characteristics. It can bounce when dropped, can stretch very far, and can copy newspaper and comic pages when pressed against it.
Silly Putty is a viscoelastic liquid, it acts primarily as a viscous liquid but also has characteristics of an elastic solid. Silly Putty is a polymer that has covalent bonds but hydrogen bonds within the molecules. These hydrogen bonds that make up Silly Putty can be easily broken. When pulled apart this is why the silly putty will tear if enough stress is applied.
Silly Putty is an elastomer. Elastomers spring back to their original shape after being twisted, pulled, or compressed. This is why when torn the Silly Putty is able to form back into one piece.
