Sound waves vibrate more than just our eardrums, they can also make visual art!

You're on a flight, and the drone of the engines is getting on your nerves, so you pop on a pair of noise-canceling headphones, and sweet, blessed silence descends. But those headphones aren't just muffling the sound -- they're actually...

Though our Sun is something we can count on to rise and set each day, it also comes with some phenomena that can catch us by surprise: solar winds. To better predict when these winds will travel all the way to Earth, we sent the Parker...

We create a Rubens\u2019 Tube to demonstrate the movement of sound waves. A tube lined with holes is filled with propane and connected to a speaker. We light the gas coming from the holes and play different frequencies and volumes of...

We use a sounding board called a sonometer to investigate how the pitch of sound changes when the length of wire being plucked changes. We change the position of a moveable bridge to change the length of the wire and discover that...
