Steve Spangler Science: Balloon Expansion

Now you can prove that an “empty” bottle is really full of matter that you can’t easily see.

Here’s a great way to actually see how air fills more space and then less space as its temperature changes back and forth between warmer and cooler. You can easily demonstrate these changes in volume with just a few items you probably already have in your home, too. In the end, you’ll prove that air is a form of matter and it takes up space even in an “empty” bottle.
