when I'm stirring sugar into my coffee, the tone of the stirring sound gets higher and higher pitched...if you pay attention, it takes a while and it raises a lot but eventually it seems to hit a ceiling...what's going on exactly? I'm guessing that the sugar dissolving is raising the pitch somehow and that the top pitch is correspondent to the sugar being entirely dissolved...but why should that change the pitch of the sound of the stirring? how does it work?
