Explanation: When you hit the drum or the baking sheet with the spoon, they vibrate. These vibrations are what cause the paper and sugar to jump. These vibrations also cause waves in the air, which cause us to hear the noise. The vibrations travel through the air bringing us the sound. If you put a hand on a radio, you can feel it vibrate. Similarly, if you turn the bass on your radio up, you can feel the beat beneath your feet.
