Easy musical instrument

For 6th grade science, my daughter needed to make an instrument that she could perform a song on that changed pitch and amplitude. She found instructions online to make a pan flute. We used PVC piping that she cut with a hand saw, then covered in cute paper, hot glued together, and then decorated with a cute tie! It only cost us about $1.15 for the long PVC pipe and we used paper we had laying around. Fun and easy project, just the way we like them!
