My instrument, the Bang-Blow was an idea from
the glass organ on an instruction sheet I used. The
Bang-Blow belongs to the percussion and wind
families. All of the bottles have two
pitches.

To make the Bang-Blow I used bottles, water,
food coloring, and paint. I got the bottles at the
store. I got the paint and food coloring around the
house. The water just came from the tap.

|
My parents and I started off by getting the
labels and dried glue off the bottles. Next I
painted the top parts of the bottles. Lastly I
colored the water.

I play Bang-Blow by either hitting it with a
chopstick or blowing over the opening like a flute.
I can change the pitch by blowing over or hitting
different bottles. If I hit the bottles from the
one with the least water to the one with the most
water the pitch goes down. If I do the same process
with blowing the pitch goes up.

It was fun because the only rule was it had
to make a sound. I liked it because I could mess
around while I did it. I learned that when you hit
a glass bottle filled with water the glass
vibrates.
