Rain Stick

I have this Rain Stick leaning up against the wall in my home office. It’s a curious stick. Inside this stick it’s filled with tiny little balls. If you grab the stick, turn it upside down, the little balls will now travel from the top of the stick to the bottom. It’s a pretty neat special process, because the movement of these balls, inside the stick, actually sound like it’s raining. Thus , for calling this stick a Rain Stick..
