You either cut a hole, or when you pump the ball, put the tube in and then when it is almost out, leave it there. It should make a hissing sound and you should be able to feel some air blowing. you kill it with a kitchen knife you pop it or take the needle outof the pump to blow it up and just leave it in the Basketball
A waterpolo ball will deflate for the same reason as any other ball, i.e. if it has a puncture.
If you want to deliberately deflate a waterpolo ball then it is the same as a football, the easiest way is to get a valve used to pump the ball up, without the pump attached. This will allow the air to escape.
if you have a pump for the ball, then screw the needle off of the end of the pump and just stick that into the ball, it will let the air out
A water polo ball has two main layers. The inner layer is an inflatable bladder that holds air and basic structure. The outer layer is a rubber fabric that allows better grip on a ball and prevents the ball from absorbing water during a game. When a ball absorbs water it becomes heavy and hard to control.
no it does not lose air in a plane it just has a hole in it or it has high or low pressure
Yes, a ball typically loses air in the winter. This is because the cold temperatures cause the internal air to decrease, which makes the pressure of the ball decrease.
No, plants lose water to the air through a process known as transpiration.
evaporation
It the ball has air in it, then an increase of temperature will increase the pressure within the ball, over the short term. Over the long term, all pressurized tennis balls lose pressure. If the ball is the pressureless type, it has no air to be affected by temperature.
Mostly the air you breathe has some water in it. Air with a bigger humidity is thicker. Not that you would notice it while walking or anything like that. So if you throw a ball in to water, it's not going to go very far, but when you throw it in the air, it flies much further. So the less there is water in the air, the less air resistance there is to slow the ball down.
Water is hydrobolic
Um probably because it evaporates....
The hot water causes the air trapped inside the ball to expand and it may pop the dent out to the original shape.
A zorb ball is a giant ball filled with air, in which people roll down a hill. It is a rather new sport. You can compare it to the famous toy for hamsters. It is also similar to the water-equivalent where children can run around on the water, using a rolling ball full of air. A zorb ball however doesn't have any water involved.
A beach ball full of air can be compared to aballoon full of helium. The overall weight of the beach ball with the air in it is less then that of the water. Water is able to move to one side so if you submerge the beach ball and let go of it the the water will move aside and under it because it is heavier. A balloon full of helium will do the same in air until it is lighter then the air underneath, but heavier then that above it.
