Science experiment: Bottle flute
Making music does not have to be a terribly noisy experience. Making music with these glass bottles can actually be quite pleasant. Give it a go and see if you can make a tune to impress.
Number of players:
What you need:
- 2 (or more) glass bottles
Fill the glass bottles with different amounts of water, without filling any to the top.
Blow gently across the top of the bottle so that you can hear a note.
Now blow gently across all of the bottles. They should all make different notes. Why?
Because blowing air inside the bottle makes the water vibrate, creating the note.
