You can get a dent out of a tennis ball by getting water, heated up to 100 degrees Celsius and place the tennis ball inside the water. Because a dent is like a small depressed place made by pressure, it easily comes out.
A wet tennis ball is a ruined tennis ball. It does not bounce as high. You can dry a tennis ball quickly by hitting it against a chain-link fence repidly for a little while. Once the ball is dry, then you can use it again.
yeahhh
To a first approximation, a tennis ball is a sphere. The volume of a sphere is V = 4/3 π r3, where r is the radius of the sphere. So measure the diameter of the tennis ball, divide by 2 to get the radius, and then apply the formula above. You could also measure the volume of a tennis ball by measuring the volume of water that it displaces.
A new tennis ball will bounce higher. Old tennis balls are considered "dead."
it become water logged, or soaked in water.
A soaking tennis ball won't bounce high because it has become water-logged
tennis ball bomb! haha. just get a tennis ball and put a firecracker in it. ive never tried it but sounds col.
The outer cover is porous and absorbs water. Being that the tennis ball is also hollow inside, the water adds more weight to the ball and thus reduces its ability to effectively bounce.
There are several places a person could shop for a Tennis Tutor ball machine. Online sites such as tennis warehouse, and sites like ebay would both have Tennis Tutor ball machines for sale.
Poke a hole in it with a pin (carefully) and allow it to become filled with water.
freeze it... the cold slows down the cinetic energy in the ball
