A bottle xylophone is one of those super simple science activities everyone should try at least once. All you need is some bottles, water and something to bang the bottles with.
We started the process with a bit of measuring, using 10ml in the first bottle, 20ml in the second and so on.
Can you hear the difference in sound? Is the pitch different? Which bottle gives the note with the highest pitch?

What is pitch?
Pitch is the degree of highness or lowness of a tone.
Conditions to test
Can you try different sized bottles?
Different amounts of water?
What happens if you have a bigger difference in the amount of water in each bottle?
How about using metal spoon and a wooden spoon to bang the bottles? Can you hear a difference?

Big thanks to Red Ted Art for the X idea, I was a bit stuck!
