"Catch a Bubble"

After watching a video titled "Catch a Bubble" @ https://www.youtube.com/watch?v=n2dLPFaehV0&feature=emshare_video_user, I am upset and even a little teary eyed. I can very much see it as offensive from a child's point of view to be told to catch a bubble in order to tell them to be quiet or zip it. It is the equivalent to telling them to shut up. We want children to learn to use their words, but then we tell them not to. Yes, we do need to have their attention at times but yelling at a child is not the way to do it. We must capture their focus with song and take the time to talk to them as another individual who deserves respect. Just because they are young does not make them less. You wouldn't tell an adult to "put a bubble in it" during a board meeting or any time you are trying to speak. Children learn by example and this is not a lesson we want to teach them.
