To make bottle pipes, you just fill glass jars with different amounts of water and blow air across the top of the jar to make a sound. You can play great songs with this experiment.
Anyways, I tried this and it was easy, but it didn't work out very well. Oh well, it was so VERY fun to play with...
The Science?
- The different masses of air inside make the vibrations.
- With less air (and more water), the sound is higher pitched because there isn't a lot of air to move around.
- With more air (and less water), the sound is deeper because there is a lot of air to move around with.
- Basically, with more air mass, there is more movement, creating the vibrations needed to create sound!
