Silly Putty

When Japan 's Asian invasion threatened the rubber supply in the United States during the Second World War, GE chemists began looking for synthetic substitutes. James Light tripped over a strange mixture: the elastic material resisted the collapse and jumped 25% more than the rubber. When not moving, this "hard liquid" moves slowly, and when it collides violently it becomes uneven. Light could not find wartime use of a fool during wartime. Later, before "Bounce Pate" or "Nut · Pate" entertained the party at the party, but before the toy marketer Peter Hodgson decided to list it as a novelty in his catalog I did not do anything else. Hodgson hired Yale students to colored plastic eggs with one ounce "stupid putty". These sold dollars so that he could make it to Easter. After New Yorker's article in 1950 was based on silly Patty, the order broke through 250,000 in 3 days. Ever since, millions of people have been sold each year. More colors, including the 1991 dark light version, appeared in 1990. People used to bounce it back, deleted images from cartoon pages, and used to clean typewriter keys, which were not originally used. The astronaut put it on Apollo 8 and fixed the tool with weightlessness!

Stupid putty is sold in egg shaped plastic containers in the form of 13 grams (0.46 oz) of clay. The Silly Putty brand is owned by Crayola LLC (formerly known as Binney & Smith). As of July 2009, 20,000 Silly Putty eggs were sold each day. Since 1950, more than 300 million silly eggs (about 4,500 tons of short tons or 4,100 tons) are on sale. It is available in various colors including glow and metallic in the dark. Other brands sometimes offer similar materials that resemble various colors that are placed in larger size containers, or that have different properties like magnetic or iridescent

As bounce spat, Silly Putty is known for its rare features: it bounces and bounces, it breaks; it also floats in liquids and can form a puddle in plenty of time. Stupid putty and most other retail putty products have added viscoelastic agents to reduce fluidity and keep the shape of the putty. The abnormal flow characteristics of Silly Putty are due to the components of polydimethylsiloxane (PDMS) which is a viscoelastic material. Viscoelasticity is a non-Newtonian flow that characterizes materials that act as viscous liquids for a long time but act as elastic solids in a short period of time. Since its apparent viscosity increases directly in proportion to the amount of applied force, Silly Putty can be characterized as inflation fluid.

In many cases, Silly Putty is difficult to remove from items with texture such as hair and clothing. Alcohol-containing hand sanitizer is often useful. Foil putty dissolves on contact with alcohol, and after the alcohol evaporates, the material does not exhibit its original characteristics. Manufacturer Crayola recommends the use of WD - 40.
