Nutty Putty Katrina Mount Brandon Williams Tiffany Burdette Nutty putty, also known as silly putty, is a polymer. “In 1943 James Wright, an engineer, was attempting to create a synthetic rubber. He was unable to achieve the properties he was looking for and put his creation (later to be called silly putty) on the shelf as a failure. A few years later, a salesman for the Dow Corning Corporation was using the putty to entertain some customers. One of his customers became intrigued with the putty and saw that it had potential as a new toy. In 1957, after being endorsed on the "Howdy Doody Show", silly putty became a toy fad. Recently new uses such as a grip strengthener and as an art medium have been developed. Silly putty even went into space on the Apollo 8 mission.”( http://www.chem.umn.edu/outreach/sillyputty.html) In this project, we will be showing the class how to make silly putty. We will also show what type of reactions will occur in the experiment. For our activity, everyone will have a chance to make Nutty Putty. We will need borax and Elmer’s glue. When adding the glue to a water/borax solution, its causes a reaction between the glue molecules and borax molecules. This causes a highly flexible polymer. Each group will have a different neon food coloring to add for their colored silly putty. Once everything is added, the silly putty will go in a Ziploc bag to be refrigerated. The original coral-colored Silly Putty is composed of 65% dimethy siloxane (hydroxyl-terminated polymers with boric acid), 17% silica(crystalline quartz), 9% thiaztrol ST (castor oil derivative), 4% polydimethylsiloxane, 1% decamethyl cyclopentasiloxane, 1% glycerin, and 1% titanium dioxide. Silly Putty's unusual flow characteristics are due to the ingredient polydimethylsiloxane (PDMS), a viscoelastic liquid. Viscoelasticity is a type of non-Newtonian flow, Characterizing material that acts as a viscous liquid over a long time period but as an elastic solid over a short time period. Because its apparent viscosity increases directly with respect to the amount of force applied, Silly Putty can be characterized as a dilatant fluid.
