small plastic pices are melted and put into a round mold and then the mold closes and it spins. a few mins later the plastic is set and they take the ball out. they put a stopper in a hole on the ball and then they fill it with air.

Hollow plastic balls are typically made using a process called rotational molding. In this process, a mold is filled with plastic resin, heated, rotated to evenly distribute the resin, and then cooled to form the shape of the ball. The final product is a hollow plastic ball that can be used in various applications.

Because they are easier to make and adequately strong. There is no point making them solid.
What is a hollow ball of cells that develops after the fertilization of the egg?
it is called a blastocyst
If a ball is dropped into a very viscous liquid it will?
A solid metal ball would sink into the very viscous liquid, a hollow metal ball would float. The speed of descent is dependent on the density of the liquid.
What is a plastic straw?
A plastic straw is a small, thin tube made of plastic that is used to suck up liquids, typically in beverages like sodas and cocktails. They are single-use items that contribute to plastic pollution and harm the environment.
Which of the following would make the best model of a water molecule?
The best model of a water molecule would be one that accurately represents its structure, showing two hydrogen atoms bonded to an oxygen atom at an angle of 104.5 degrees with the oxygen atom having two lone pairs of electrons. A ball-and-stick model or a space-filling model would be suitable choices for representing a water molecule.
How do you make a hollow plastic ball?
go to the PC and go to your box and clck on ball capsules.
What happens when a hollow plastic ball and a sollid metal ball is dropped in a vacuum and gravity is the only force?
In a vacuum with gravity as the only force, both the hollow plastic ball and the solid metal ball will fall at the same rate and hit the ground simultaneously. This is because in the absence of air resistance, the mass or density of the objects does not affect their rate of fall.
What is the density of plastic in kgm3?
That depends on many things including but not limited to; 1. how thick the plastic is (if it's solid or just a shell around a hollow center) 2. the type of plastic, as different plastics have different densities. 3. if it is a hollow ball, the size of the ball will make a difference as the greater the volume of air compared to the volume of plastic will lower the density

Why is a golf ball heavier than a table-tennis ball even though the balls are the same size?
Because the table-tennis ball is hollow on the inside and made of a lighter weight celluloid, while the golf ball is made of a hard outer shell of plastic with rubber compacted on the inside. The golf ball is denser, meaning it has more mass per volume (since they're the same size), so it is heavier.
Is a pool ball hollow?
No
How do you make a hollow ball of string?
Get a rectangular piece of cardboard & bend it into a circle .Paste the inside with hot glue (glue gun) and then put the string on it. When the paste it dry, cut the cardboard & there u have it. A HOLLOW BALL OF STRING!
Why it is possible to catch a solid ball as compared to a hollow ball of equal radius?
The solid ball, will have more mass in comparison to the hollow ball of the same radius. Since, momentum of an object is the product of its mass and velocity, the solid object will have more momentum. Therefore, the force required to stop the solid ball will be much greater than the force required to stop the hollow ball (since, the hollow ball will have less momentum because of its less mass). That's why its difficult to catch a a solid ball as compared to a hollow ball of equal radius.skhatti
