I'm forever blowing bubbles

We were in Stratford this afternoon, when we saw this chap demonstrating his bubble-making-equipment. If you bought one, you could have free refills of the bubble-liquid all day, which seems like a pretty good deal to me - especially if you bought one at 9 a.m. 
The adults seemed to be having more fun than the children. The "Simon Cowell lookey-likey" in the background appears to have a bubble on the end of his nose (especially if you look large)!
One landed on a chap's head and quivered there for a second or two before bursting. Couldn't quite get the camera in that direction fast enough.
