Silly String

Silly String (generically known as aerosol string) is a children’s toy of flexible, sometimes brightly-colored, plastic string propelled as a stream of liquid from an aerosol can. The solvent in the string quickly evaporates in mid-air, creating a continuous strand. Silly String is often used during weddings, birthday parties, carnivals and other festive occasions. Silly String is often sold at dollar stores or party stores.

Contents

Composition

The material is a polymer-based resin which was originally formulated using the chlorofluorocarbon propellant Freon 12, one of a group of compounds believed to damage the ozone layer. Within a year of Silly String’s introduction the United States banned Freon 11 and 12. The manufacturers then changed the formulation to use permitted propellants. [ 1 ]

History

Silly String was patented by Leonard A. Fish and Robert P. Cox. A United States Patent was issued to them in 1972 as a «foamable resinous composition». Cox died in February, 2008.They invented Silly String, which they originally named «Squibbly,» while developing an aerosol spray cast for limbs. This information was supplied by Leonard Fish, co-inventor. Silly String and its imitators are reputed to be the largest selling novelty toy in the world because people buy multiple cans and use the Silly String quickly. [ citation needed ] It is polymer-based, likely 11-16% polyisobutyl-methacrylate and 0.5 to 4% sorbitan trioleate dissolved in a solvent that evaporates in the air and acts as a foaming agent. The pressure in the can propels the mixture a distance of up to 20 feet (6.1 m). Other alleged ingredients are a small amount of isopropyl alcohol and plasticizers like dibutyl phthalate.

Silly String was licensed to and produced by Wham-O, in a range of colors including blue, red, and green, until the rights were sold to the Car-Freshner Corporation, the maker of Little Trees, in 1997. The U.S. Patent #3705669 includes a clear description of preferred implementations. [ 2 ] Similar toys are Goofy String, Streamer String, Wacky String and Nickelodeon Smatter.

The can is advertised as containing «over 400 feet (120 m) of string.» One measurement has shown over 1,600 feet (490 m). [ 3 ]

Safety

The composition of Silly String is fairly safe, but the evaporating fluorocarbon solvent can be quite cold, theoretically capable of causing frostbite. The mixture is a very weak skin irritant. The solvent is somewhat flammable, although the polymerized string is said to be flame-resistant. The manufacturer does not recommend use near an open flame or even a warm light bulb. [ 4 ] The flammability of Silly String as it comes out of the can has been highlighted in several home videos of Silly String sprayed near birthday cakes with lit candles, causing small but frightening fires.

Silly String may on rare occasions damage the vinyl surfaces of inflatable structures, upholstery, vinyl wallpaper, and automobile vinyl tops.

Military use

Silly String and similar products have been used by American and British military forces to detect tripwires for explosive booby traps. The string is sprayed over the suspected area, and if the string falls to the ground, no tripwires are present since the string would catch on the tripwires (but is not heavy enough to activate the explosive). [ 6 ] [ 7 ] [ 8 ]

As of 2006 [update] it is being used by U.S. troops in Iraq for this purpose. [ 9 ] [ 10 ] [ 11 ] However, because the material is an aerosol, it cannot be shipped privately to Iraq and it is not provided by official channels. Thus, 80,000 cans were unintentionally stockpiled in New Jersey. [ 12 ] In October 2007, a shipping company with the required credentials was finally found. [ 13 ]

The use of Silly String has been banned in several places for various reasons.

It has been banned in the city of Ridgewood, New Jersey and a number of other places, and also at some public gatherings and events. [ 14 ] The town board of Huntington in Long Island banned the sale of Silly String within 1,500 feet (460 m) of the route of a parade. [ 15 ] [ 16 ]

How Silly String Works

The Chemistry of Silly String

Whether you’re spraying Silly String in a hunt for tripwires, at a celebration or just for fun, you’re probably not thinking too much about its physical properties. But those properties are responsible for everything it can do, and taking a moment to define them can help you understand how the aerosol string works.

Silly String starts as a liquid inside the can and becomes continuous string outside of the can. The string is lightweight and slightly adhesive; it can stick to walls, clothing and other surfaces. It’s also cohesive; unless you physically pull it apart, it holds itself together in one long piece. Most importantly, its adhesive strength is less than its cohesive strength. In other words, it takes less force to pull a strand off the wall than it takes to pull it apart. That’s why you can usually grab Silly String after it dries, and the bulk of it will come off a surface in one big tangle. Exceptions are if you spray it at very close range, onto highly textured surfaces or onto surfaces that interact with its ingredients, like vinyl. In those cases, cleanup can require substantially more effort.

All of these properties come from Silly String’s ingredients and the way they interact when extruded through the nozzle of a normal aerosol can. They create foam surrounded by a sturdy skin. The foam is light, and the skin is flexible and tacky. The foam and its skin come from three primary ingredients:

Surfactant helps the resin foam and expand. Too much surfactant would make too much foam, and you’d end up with a texture more like shaving foam or mousse. But too little surfactant would make the strands too sticky, and you wouldn’t be able to remove them from surfaces.

Without the propellant and the aerosol can, Silly String would have no foam. At normal air pressure, the propellant in Silly String would be a gas. The high pressure inside the can, however, keeps it in its liquid state, and all of the other ingredients are dissolved in it. When you press the nozzle, a valve opens inside the can, giving the highly compressed liquid a chance to escape. Liquid rapidly moves up the tube inside the can, traveling from the high-pressure environment inside to the lower-pressure environment outside. Outside of the confines of the can, the liquid propellant quickly becomes a gas, causing the remaining ingredients to foam. You can read more about aerosol cans in How Aerosol Cans Work.

The movement of propellant is central to the physical qualities of Silly String. Unfortunately, it has also lead to safety and environmental concerns. We’ll look at those in the next section.

Other ingredients can adjust the strength, stickiness, weight, color and flammability of Silly String. These include:
