Serendipity is the art of looking for one thing but finding, quite by chance,
something different and more valuable. An American inventor, Charles Goodyear,
was trying to make rubber useful. In its natural form, the substance became soft
and sticky on cold days. Goodyear heated rubber with sulphur, hoping to make a
mixture that would remain dry and flexible at all reasonable temperatures. Success
eluded him until, in 1839, he accidentally spilled the mixture on a hot stove.
He peeled it off and found he had created the flexible rubber he wanted. The extra
heat of the stove had led to the discovery of vulcanization.
