"Quiet Spray" - found at The Lemonade Stand blog. As they suggest: "...spray the ROOM to signal children to get quiet. Or you can just leave the bottle empty. Mine love the mist in the air....I do not condone spraying a child! As much as you might want to! Ha!"
I thought this was a cute idea, even though I don't have too much trouble with talking in classes (knock on wood...), but every so ofter there is a class that is just the right mixture of personalities to create the chit-chatty class. Sometimes it only takes one or two chatterboxes to make you want to reach for the quiet spray...especially in my high school classes :)
On second thought, maybe I should make some interchangeable labels:
"Spotting Spray" (NOT to remove spots, but to add spotting to turns!)
Any others you can think of for when you're having "one of those days"?
