Wiggle-O-Meter

I made this a while ago, thinking I would need it often. As it turns out, I've only pulled it out once. These kids aren't too wiggly. They're pretty darn attentive. Too bad.
The time I did use it, when Junior primary was being a little too noisy, I pulled it out and said, "Oh no, I just checked my wiggle-o-meter and there's bad news. According to this, we have a serious case of the wiggles on our hands." I told them that we needed to get the level of wiggles down. I had a couple kids lead us in "Do as I'm Doing". Each time we finished singing, the red would go down more and more until it reached "calm and cool".
