Last time I was out bubbling at night, a beautiful young woman happened along and started exclaiming. In this voice. She said I was a genius. I said no, I was just making a living. I was testing soap.
Giant bubbles are a great icebreaker.
Even if your guests are bored stiff, when a big sphere sails over their table and pops, you're sure to get a response. People find bubbles easy to talk about. A blower likes bubbles so much, he'll crawl underneath and blow to keep it flying and alive. But most kids are poppers by instinct. You have to train them to be blowers.
