Useless Fact for the day - Silly Putty

Silly Putty started as a mistake in a New Haven
laboratory, and turned
into a consumer hit in the 1960s by sheer chance.
According to engineers,
Silly Putty is a self-contradiction. Chemically,
it is a liquid, but it
resembles a solid. The molecular structure will
stretch if the structure
is slowly pulled. But if tugged, it snaps apart.
The toy has a rebound
capacity of 75 to 80 percent, whereas a rubber
ball has only about a
50-percent bounce-back. A silicon derivative,
Silly Putty won't rot; it
can withstand temperatures from -70 degrees
Fahrenheit to hundreds
degrees above zero. On top of all that, it picks
up newsprint, often
sharper than the original.
