I need to make a windchime for a girlscout project. Easiest way?

So my girl scout troop is doing a nature garden, and sensory plants and birshouses, and we need a windchime. So my job is to research how to make a windchime, home made. We were thinking Pcb (or whatever theyre called) pipes, but that would just make a hollow sound right? So what can we use to make a beautiful sounding winschime. thanks!!!
