I’m going to explain how the sound comes from the shaker. Because it’s simple to create, it’s pretty simple to explain.
The rocks bounce around in the can when you shake it, and it hits the inside of the can. The vibrations from the impact travels from the can to your ears.
When water is applied, the rocks’ impact isn’t as quick and hard. The water slows it down so the sound is softer. Also when you shake it, you hear the water hitting parts inside the can too.
If you left the can no sound would come out because you’re not giving any motion to move the rocks and water. Even if you rolled it, you’d still get sound because the rocks and water are rolling around.
Now you can see how the shaker is made and how it works. It works because the rocks bounce around in the can when you shake it, and it hits the inside of the can. That’s also why it’s called a shaker!
