BEEP BEEP by Soledad P. This is my instrument, “BEEP BEEP”. I named it like this because when I play it I can hear that sound. The materials I used to do my original instrument are a box, beans, a glass, and water.     To make my instrument first I used a box which I decorated with beans. Then I put a glass on the box and I added water. My brother helped me decorating my instrument but I did it all. To play my instrument you have to moisten your index finger with water and then rub the edges of the glass.
