Before television was invented, tennis balls were white. They would have remained this way if television had not been broadcast on live TV This was because people couldn't see the white tennis balls flying across the screen. So, they were changed to neon green/yellow so that viewers could see them.
New tennis balls are considered fresh and not "flat". Old tennis balls exposed to play and air become flat and do not perform normally in a match.
The centers of tennis balls are rubber and rubber hardens with age.
Give them to someone with a dog.
New tennis balls bounce higher than old tennis balls because they have more elasticity and air pressure which allows them to compress and decompress more easily upon impact with the ground. As tennis balls are used, the felt covering wears out and the air inside the ball escapes, leading to less bounce.
They improved them a lot! If your question would be more specific, it would be easier to answer. The tennis balls used to be wads of hair or wool wrapped in stuff, but now they are more rubbery for bounce. I don't know exactly how.
The 'people who fetch the tennis balls' are called ball boys and ball girls. The ball boys and ball girls are usually under 18 years old, with some being as young as 10 or 12 and others being as old as 16.
A new tennis ball will bounce higher. Old tennis balls are considered "dead."
Some noe in my town has put two tennis or golf balls in a sock and put the sock on the back of their car making it look like a scrodum, or ball sack. Most pimp cars are old or new lincolns with badass rims.
The term 'tennis ball hopper' is pretty broad, covering a variety of different tennis court equipment. Tennis ball tubes can be used to pick up balls and as a dispenser you hang on the fence. They generally hold about 15-18 balls and are great for individuals who don't hit more than a couple of dozen balls in a session. Another type of tennis ball hopper is a ball basket. You typically use these to pick up balls by pushing the bottom of the basket on the ball and squeezing it into the storage bin. Many of these models allow you to flip the handles so that the basket can be used like a stand that you can easily grab balls out of. Another type of tennis ball hoppers are the ball carts. These look somewhat like grocery carts. You can't use them to pick up balls, but they can hold about 200-350 balls. One model in particular has collapsible legs that allow it to fit in the trunk of a car. Finally, there are the ball mowers. These are designed to quickly gather large numbers of balls into a container. You push them like a lawn mower and the mechanism inside the mower feeds the ball into a storage unit. Some models of mowers can double as stands or allow you to set up the storage unit like a stand.
"To Be By Your Side" by Nick Cave ^ that is all the OLD ones, What about the one with a tennis ball shooter, ahooting tennis ball on a tennis court with the rich hobo guy sitting in a lawn chair and there are a ton of dogs jumping catching the tennis balls. The music sounds electronic like and saxophone or something
You don't actually hit them better. When you hit a dead ball it sounds like you hit it much louder, but a new ball is always ideal for hitting.
Tennis balls are very useful for more than just tennis. Old people put them on their walkers, and people throw them to their dogs. But tennis players use them for, well, tennis. I think the biggest market would be rackets and re-stringing them.
