Here's a great way to have some fun with a helium balloon and learn while it seems to defy the laws of nature, it really doesn't.

Common sense and knowledge would lead most of to think the helium balloon would behave exactly like the pendulum in the video. But, it actually does the opposite.

The simple explanation is the helium in the balloon is lighter than the air around it, so when the air starts moving backward, it leaves a space for the helium balloon to move forward. Watching the video will help you better understand why.

This fun activity is incredibly easy to replicate and offers a great lesson in science at the same time, so give it a try.

Plus, the next time you have a big helium balloon bouquet that starts out in the back seat and ends up in the front when you start driving off with it, you'll know exactly why.
