Would the balloon inflate , deflate or do nothing if I injected the balloon with nothing but vacuum? Is it even possible to inject vacuum into an unflated balloon?
russ_watters said:To me, "inject with a vacuum" is just a meaningless self-contradiction. Can you describe exactly how you would do that?
As simply as I can put it: you're misusing the word "inject". Vacuums are created (usually) with a vacuum pump. The word "inejct" does not apply.pentazoid said:But don't you have to create a vacuum environment in a proton accelerator in order to create conditions where there is no material except protons and only protons smashing into each other? Why could you not inject vacuum into the inside of a balloon?
contract?LURCH said:and making it expand.

Experiemental vacuums are created in rigid chambers that compress very little in response to pressure differential inside and outside. The balloon is very flexible and there is only a tiny difference between inside and outside pressure, when the baloon is expanded. You'd need a rigid balloon in order to have the pressure inside less than the pressure outside.pentazoid said:But don't you have to create a vacuum environment in a proton accelerator?
Sorry I thought you meant - and then open the container.LURCH said:No; I'm saying that, if you put an evacuated container inside a balloon, the container will occupy space, displacing air and causing the balloon to expand.

andy taylor said:the balloon in vacuum is actually a very old classroom demo to show the power of vacuum. assuming the balloon is flat and empty and in the belljar witha nominal vacuum applied within the jar the balloon will inflate.
Injecting an unflated balloon with vacuum involves removing the air inside the balloon using a vacuum pump. This creates a low pressure environment inside the balloon, causing it to expand and inflate.
The materials needed for injecting an unflated balloon with vacuum include a balloon, a vacuum pump, and a rubber stopper or cork to seal the balloon's opening.
Injecting an unflated balloon with vacuum can be used for various purposes such as demonstrating the properties of air pressure, creating a vacuum-sealed container, or simply as a science experiment.
Most balloons can be used for injecting with vacuum, but it is important to choose a balloon that is made of a strong and flexible material to withstand the pressure difference. Latex and rubber balloons are commonly used for this purpose.
Yes, it is important to use caution when handling the vacuum pump and to avoid over-inflating the balloon. It is also recommended to wear safety goggles and gloves to protect against any potential bursting of the balloon. Additionally, children should be supervised by an adult when conducting this experiment.
