Silly String
Synopsis of Toy
No one knew what it was made of… in fact, people still don’t know what it’s made of. Certain cities have banned it, and people regularly get in trouble for using it in public places. One poor kid was even denied his high school diploma because he decided to celebrate his graduation with it. Silly String has baffled scientists, enraged teachers and parents and delighted mischievous kids everywhere for over thirty years of gooey, stringy madness.
Precious little is known about the origins or ingredients of Silly String. First introduced to the gag-gift market in 1969 by Julius Samann, Ltd., the only thing that is known about Silly String is that it is non-toxic, non-flammable, and completely free of chlorofluorocarbons. Beyond that, no one, save the manufacturer, knows the exact ingredients of this top-secret tool of pranksters. No ingredients are listed on the can and the manufacturer refuses to say what they are, claiming that is information is “proprietary.”
Whatever Silly String is comprised of is combined with propellant gas in an aerosol can. When the nozzle is pressed, a thin, pressurized stream of foamy material shoots out, coating a desired target from up to three feet away. It feels wet and cool when first ejected, but quickly solidifies into a Styrofoam-like consistency. Neatniks need not worry; the rumors that Silly String can ruin clothes, carpets, etc. are not true. The only substance it is known to stain is vinyl, so keep it away from that pair of vintage go-go boots and the interiors of American-made automobiles from the 1970's.
Since its introduction, Silly String has become a staple item at novelty stores, party supply stores, and toy emporiums. It has also popped up on television and in films, most notably the Silly String fight in the Tom Hanks classic Big. In recent years, Silly String has run into some "social" problems, including being banned from a long list of public gatherings that includes everything from school graduations to Mardi Gras. In spite of The Man trying to keep Silly String down, it continues to be popular amongst kids and the young at heart for the harmless, goofball fun it provides. But don't try and figure out what it is. Just look what happened to the Soviet Union (and they still never got the secret!)
