Inflate a sealed balloon in a vacuum chamber

Inflate a sealed balloon in a vacuum chamber

A partially filled balloon is placed into a vacuum chamber. When the vacuum is turned on, the pressure exerted on the balloon decreases and the balloon can expand until the bell jar is completely filled. When the air is allowed back in the jar, the pressure is reestablished and the balloon returns to its original volume. This is a great example of Boyle's Law which shows an indirect relationship between pressure and volume.

As you pull out the air, the pressure on the surface of the balloon is released, letting it expand.

And in a complete vacuum, with a filled balloon, it will pop, because that is 14.5 psi on the balloon.
