Bubbles

I went into town with my son, and while he was looking into mobile phone contracts, I happened across two street entertainers blowing bubbles. I'm a big kid about bubbles. I can blow bubbles 6 " / 15 cm across sometimes, (hey, I used to play clarinet, and I learned some breath control) but that's about my limit. These people were using big loops of cloth and the wind, and the bubbles were too ginormous to be round. I was jealous - I wanted to play too.
