They are the bane of my existence. Every time one of my kids see the bottles, they act excited. Can we go outside and blow bubbles? PLEASE? And every time I say yes, the same thing happens, without fail. We go out, I blow bubbles (and/or one of the kids does) and before 10 minutes is up, the bubble bottle gets spilled (or dumped) all over the floor. End of scene. And I tell myself that we are NEVER doing this again. Even so, every few months, I think THIS time it will be different. Maybe THIS time.
