To restore the insulating ability of a wet down jacket, you can first gently squeeze out excess water without wringing it. Then, place the jacket in a dryer on low heat with a few clean tennis balls to help fluff up the down insulation. Alternatively, you can lay the jacket flat to air dry in a well-ventilated area, periodically fluffing it up by hand.
It depends. If a tennis balls are hit with the same amount of force, then the dry tennis ball will travel faster and farther. However, if the two tennis balls begin traveling at the same speed, then the dry tennis ball will slow down more rapidly than the wet tennis ball. The reason is the added mass of water. It would take more force to make the wet tennis ball fly as fast as the dry, but the added mass also requires more force to slow down the wet ball.
you have to take it to the dry cleaners
Tennis balls are affected by the environment in a few ways. The environment can affect how it bounces. Warm air makes the ball expand causing it to have a higher bounce. Cold air makes the ball contract and can make it harder to bounce.

It depends on the material of the jacket. Usually, machine washing should be done on a delicate cycle using a cold water wash, such as Woolite. It would be wise to let the jacket air dry, smoothing it out as soon as the washer ends to prevent wrinkles and/or shrinking. I would not advise washing leather.
Technically, a frozen tennis ball will not bounce well because of the temperature. The elasticity is one of the factors in which a ball bounces and when things are colder, there isn't as much elasticity, so it will not bounce as well. Therefore, a dry ball (as long as it wasn't frozen in a container) will bounce better than a frozen one.
wash it, then dry it with 2 tennis balls in the dryer, let them bounce around in there and it will be softer when you are done, using some fabric softener in the wash will also help.
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.
One way to clean a micro-suede jacket is by using a sued brush. Taking it to a dry cleaners may be necessary if the brush does not clean the jacket.
