Question: What will happen to the sound if I cut the straw shorter and blow through it?
It will probably make a higher sound.

Straw Length: Results:
Long:15cm (When I blew into it is had a high kind of sound)

Blowing into the straw that our class experience. It makes a type of sound like a party popper. The shorter I have cut the straw into triangles the higher the tone of sound it makes. It makes me laugh sometimes when I blew into it. Like Effect fail.
It was a great thing we had try out. We learn a lot from that it is gives me great Ideas about sounds.
