DOUBLE RAINBOW by Kate

How I made my instrument:

I used 7 thin glass bottles (because there are 7 letters in the musical alphabet) and put water in them in such a way that it looks like stairs. Try to match the sound of your bottles to pitch of a scale. Then I put egg dye in the bottles to look like a rainbow. The color order is red, orange, yellow, green, blue, purple and black. Next, I found a spoon to hit the bottles. Finally, I put tape around all of the bottles so that I could bring them into school.

How my instrument makes a sound:

There are 2 ways to make a sound: you can strike them with the spoon or blow over the top of them.
