Fun Science Experiments Using Balloons

Who doesn’t love a colorful balloon floating overhead? They’re pretty and fun, and they’re also great to use for science experiments. Most of these experiments only require balloons and common objects like fans, vinegar, baking soda, coins, string, or egg cartons. You can do these experiments at home whenever you feel like playing around with science or for a school science project! Soon, you’ll see how fun and easy it can be to learn about all sorts of scientific topics, like electricity, gravity, chemical reactions, air pressure, and even black holes!
