How To: Inflate a sealed balloon in a vacuum chamber

Want to learn the principles beyond Boyle's Law in a way other than just hitting the books and getting bored to death? Then a science experiment is key.

This video teaches you how to inflated a sealed balloon inside a vacuum chamber. The pressure exerted on the balloon will decrease, allowing the balloon to get bigger and fill the entire chamber. If you open the chamber, the balloon will return to its original size.

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

and the pressere becomes much greater in the ballon

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