ball inside a whistle? Why?

What purpose does the ball inside a whistle serve? My kid just got a clear whistle and watching him use it... the ball just sits there.

This explains it. Normally they're not supposed to just sit there, but bounce around. If it's clear, is it made out of plastic? Maybe that's messing with some of the properties compared to a metal whistle.

If you do it right, the ball vibrates and the whistle makes a sort of trilling sound instead of just a tweet sound. Here is an animation. They call it "the trilling sound you associate with a quality whistle blast."

I just happened to see a "How it's made" about whistles. I think your kids would like this video.
