Silly polymer

Also, the 50 percent glue solution and the glue—borax mixtures should not be poured down a drain because they can form clogs.

The Silly Putty timeline puts things in a bit of historical perspective, with Crayola Silly polymer the rights to Silly Putty during my childhood, followed by a resurgence of interest in the stretchy, bouncy medium and its egg-shaped containers in the 80s.

Students make their different formulations of poly vinyl alcohol by adding different amounts of sodium tetraborate saturated borax solution. Explain how you redesigned the formulation procedure.

Polymers Are Like TV: Is the formulation more or less rigid or elastic? Add an additional 10 mL of water to the cup Silly polymer mark the water level. After having gone through about 30 or 40, Fish came upon one that produced a nice string, which shot about 30 feet across the room.

The product originally used chlorofluorocarbon propellant Freon 12 mixed with Freon 11both part of a group of compounds that damage the ozone layer. After a long period of time, it will return to its original viscosity.

Physical properties are qualities that can be observed during a physical change, like the melting of an ice cube. The Original Silly Putty. One day later, Fish received a Western Union Telegram asking him to send 24 cans of "Squibbly" for a market test immediately, signed by the same individual who had kicked him out.

The two remaining hydroxyl groups attach to the boron and then react with two additional alcohol groups within an adjacent polymer chain. Student responses will vary.

Fish, an inventor, and Robert P. Many familiar and commonly used polymers are synthetic, but there are also naturally occurring polymers, including cellulose, starch, proteins, silk, chitin, and rubber.

As the amount of tetrahydroxy borate anion shown in the third step-wise reaction increases, a higher probability exists to form more borax cross-links within the poly vinyl alcohol. There are two different kinds of properties, chemical properties and physical properties.

Viscoelasticity is a type of non-Newtonian flowcharacterizing material that acts as a viscous liquid over a long time period but as an elastic solid over a short time period. Some descriptive words used to describe a chemical might be: Procedure Background Students synthesize polymeric materials and create two different formulations of imitation Silly Putty.

Silly Putty will dissolve when in contact with an alcohol; after the alcohol evaporates, the material will not exhibit its original properties.

How many is "many many many"? Are there other ways to change the recipe in order to change the physical properties of the polymeric product? It additionally calls for 0. This family science activity may inspire nostalgia, but your kids will have a blast exploring the tactile medium.

Then pour out the water. So, things that are made of polymers look, feel, and act depending on how their atoms and molecules are connected, as well as which ones we use to begin with!

Some bags may require more mixing than others. The full Science Buddies Project Idea can be used during science fair season, but the general procedure gives you a blueprint for turning the project into an exciting family activity:ShinyStuffCreations makes and sells funny, unique and silly polymer clay jewellery.

With themes like miniature food, objects or animals the jewellery is recognisable and will put a smile on everyones face!5/5(K). Silly Putty: Synthesizing a Polymer Adding Elmers School glue (or generic brand School Glue) to a water/borax solution causes a chemical reaction.

Experiment 3 A Silly Polymer. Cross-Linking a Polymer to Create Everyone's Favorite Childhood Toy, Silly Putty Objective: The objective of this experiment is to cross-link a polymer and observe the changes in the physical properties as a result of this cross-linking.

The changes in physical properties of a cross-linked polymer are also studied.

Putty Science: Family Fun with Polymers

Changing the ratios of polymer and sodium tetraborate solutions in your imitation Silly Putty will affect how it bounces, stretches and goos!

Vocabulary/Definitions cross-link: A covalent bond linking two polymeric chains together, sometimes facilitated by. The polymer chains are quite flexible, and when they are particularly long, as in the case of silly putty, they can become loosely entangled around one-another.

This is what causes PDMS’s viscoelasticity. The physical and chemical properties of Silly Putty are what make it so much fun because it is a polymer that is stretchy and bouncy! But Silly Putty is not the only polymer.
