We all know that hair dryers are great to use after a shower, but today you will discover that they can also come in handy if you want to perform a neat science trick! In this “science snack” from the Exploratorium, you will see how air pressure impacts a ping pong ball that is balanced in an airstream from a hair dryer. Once you’ve mastered this you can even try it on a larger scale with a vacuum hose and beach ball!
