Purpose: To see if their is an effect on golf balls after being soaked in water?

Independent Variable: My three different brands of golf balls.

Dependent Variable: Will water seep in or not and if it seeps in will it have an
effect on the golf balls distance.

Control: My unsoaked golf balls.

Reasearch: Per information sent to me by Titleist: Exposing a golf ball to water
has a negative effect on the golf ball’s performance. On average, after one week
submerged in water, a two piece golf ball will lose 6 yards off a drive. The loss of
performance for wound construction is even more significant, averaging a loss of
distance of up to 9 yards.

The History of the Golf Ball: The first ever golf ball was called the Feathery and
introduced in the 1400’s it was a stitched leather pouch soaked and then stuffed
with goose feathers. Upon drying, the feathers expanded and the leather
contracted, forming an extremely hard mass. This was hammered round and
painted white. The feathery sometimes flew over 300 yards and was durable - until
it got wet. Then it would split open. The Gutta percha was introduced in 1850 and
was made of a rubberlike sap from the Malaysian sapdilla tree. The material was
heated to soften it and then hand-formed into a solid, one piece ball.Gutta percha
was black, so the early balls were painted white. Easier to make, less expensive,
and more durable, the gutta revolutionized golf. When golfers discovered that
balls and nicks flew longer and straighter then new ones, manufactures began to
give them a textured, even pattern surface. The most popular early pattern was the
bramble, which featured raised round bumps in concentric circles. the first wound
rubber ball was introduced in 1898. the three-piece Haskell was the first ball to
mix distance and control. Cleveland entrepreneur Coburn Haskell, with Akron
BFGoodrich engineer Bertram Work, wound continuous rubber thread under
extreme tension around a small, solid rubber core, and wrapped the result in a
gutta percha cover. Balata rubber soon replaced gutta percha, and dimples first
appeared in 1909. The first two piece golf ball was introduced in 1968 by Robert
Molitor a Spalding researcher who developed a ball consisting of a solid center
with a tough thermoplastic cover. The two-piece ball sacrificed control for
distance but has improved so much that today it represents 70% of all golf ball
production.

Interesting facts about dimples: Through my research I have found that even the
slightest change in a dimple pattern could cause you to lose many yards off of your
shot. By adding 0.001 inch to a dimples depth could boost a drive length by 15
yards. Hitting a shot 250 yards without dimples could only go about 125 yards.
Shallow dimples allow the ball to fly higher but without much roll at the end.
Deeper dimples create more turbulence and flatten the arc of the golf balls drive.
Dimples disrupt the flow of air around the ball, thereby decreasing drag, or the
airs resistance to the balls movement through it. The dimples enhance lift as the
ball’s spin increases the air velocity over the ball and reduces it below the ball.
Air pressure thus is created underneath and a vacuumlike condition above, similar
to the lift generated by the wings of a plane in flight. More important than the
number of dimples is their coverage - the amount of a balls surface that is dimpled
and how they are distributed. The goal is more uniform dimple coverage. About
70 to 80% of the golf ball is covered in dimples. The majority of dimple designs
today are based on the icosahedralpattern which Titleist introduced in 1973. This
pattern divided the cover into 20 identical triangular faces. Titleist experiments
with some 50 to 100 dimple patterns a year and has eight in current production.
In 1909 spalding invented the first ball with dimples and now make three basic
dimple patterns. Even the shape of dimples have changed over the years. No
longer are they all round. Wilson’s truncated cone dimple design features a flat
bottom and sidewalls, for reduced drag. Bullet and Aero which I used in my
project have new dimple designs. On Bullets new ball one third of the dimples are
square for increased backspin and Aero a brand new ball made by Top Flight has
round and tear drop dimples. Aero’s “tear drop” shaped dimple design reduces
inefficient areas of the dimple which cause drag. Less drag equals more distance.
Until 1983 most golf
