A tennis ball is very distinctive and are used by millions of
children and adults all over the world for playing tennis, of
course, but many, many other less formal games too. They are not
merely the correct size for tennis, presumably anyway at 2.7 inches
or 6.7 centimetres in diameter, but they also fit neatly into a
hand or a dog's mouth. Therefore people use them for playing catch,
for various games of softball like rounders and for throwing for
the dog to retrieve. When I was a child, all tennis balls were
white, but now you would be very hard pushed indeed to find a white
one if, if indeed it is at all possible. These days, all tennis
balls are day-glow colours like yellow, green and orange.
Presumably this change was made for the purpose of visibility on
the TV screen. The word 'tennis' comes from the French - 'Tenez'
(pronounced 'teney'), which meant 'Take up Position' or simply
'Begin'. The origins of tennis were almost certainly well over a
thousand years ago, when it was played by monks. The racquet or
racket was the palm of the hand and the ball was wooden. No-one is
really certain whether the next innovation was to wear leather
mitts or to modify the ball to leather, but whichever it was, there
was obviously a move to make the game less painful. When the ball
changed from being wooden, it was manufactured of animal skin, most
often leather, sewn up with sinews and stuffed with anything that
came to hand, such as straw, wool and hair - animal and human. The
thing is that these early wooden and leather balls did not bounce,
so the game was very different back then. In due course, the monks
began using 'racquets', but they looked more like bats than modern
day tennis racquets. In Disraeli's book, "Sybil" (1845), the plot
reveals how Lord Eugene De Vere was to travel to Hampton Court to
play tennis, so the game was a familiar sport then, but it took
until the late Nineteen Century for the game that we know today to
become formalized by a set of rules. In 1874, Major Walter
Wingfield was granted the patent for the rules and equipment of
'lawn tennis' and not much has altered since. The following year
tennis courts were established in the USA and then the game of
tennis spread like wildfire. Wingfield laid down the rules of the
game and the type of apparatus to be used. The game has not altered
much since then in essence, but it has changed a great deal
nevertheless. The outline of the court is different now and science
has been applied to the equipment to improve it. The initial ball
in the late Nineteenth Century was manufactured of solid rubber and
so would have been fairly weighty, but at least it did bounce which
immediately made the game more interesting and more energetic. A
bouncing ball made tennis into a more interesting game to play and
a more interesting game to watch. The rubber ball permitted tennis
to be a spectator sport that crowds would pay to watch. Modern
tennis balls have a rubberized skin, which is about eighty percent
rubber, filled with air and covered by a layer of 'hairy' felt. The
felt is vital because it allows the surface of the ball more grip
and can standardize the bounce too. It also gives the ball a more
predictable flight path even in the presence of wind. The last
aspect of modern tennis balls is the air inside. This can either be
pressurized or non-pressurized. Pressurized balls give a better
bounce when new, but they lose pressure with time and so are less
consistent, whereas non-pressurized balls actually get better
slightly with use, which is considered a benefit. If you are a
