|The holder for the world
record for the largest ball made from rubber bands is John Bain
of Wilmington, Delaware. Or at least John held the record at one
point; it's a record that's subject to frequent change. The
statistics are listed below. Rubber band balls are very popular,
and, yes, the Guinness World Records publication does have a category for
the largest rubber band ball.

"discovered" natural rubber in Haiti where he saw the natives there playing
with balls made from the sap of a tree called "cau-uchu."
We can thank John Priestly
for the term "rubber." He found that natural rubber could erase or
rub away pencil marks, hence he called the material "rubber."
No one's absolutely sure
about exactly how or when rubber bands came into existence. One theory
is that someone cut an old bicycle inner tube for securing a certain object.
Then others found it very useful and convenient...even though it was not
as elastic as today's rubber bands.
Just like people, rubber
bands age...and for similar reasons. Exposure to heat, air and sun
light contribute to rubber bands becoming brittle or even disintegrating.
To extend life, rubber bands should be packed in an air-tight bag or container,
and stored in a cool, dark place.
not be nearly as useful as it is without the process known
as VULCANIZATION. Natural rubber itself is
soft, not very resilient, breaks down easily when over-stretched
and is not able to return to its original shape after being
stretched. This special heating process discovered
by Charles Goodyear overcomes these shortcomings.
Generally speaking, higher-quality
rubber bands weigh less than lower-quality bands. Higher-quality
bands are also typically stretchier than lower-quality bands. It's
primarily due to the purity of the rubber used to make the band.
Because they weigh less, more expensive (per pound) high-quality bands
are often a better buy. Why? More bands per pound.
