I'm sure you know what I'm on about, the small ones end up ganging up on you and become one huge posse of bubbles that seem to be prepared to do anything to leave the bath clinging on to your hairy shins.
It could be something to do with the fact that any two masses which in close proximity are attracted together - gravity really. It's kind of the same principle as the moon staying in orbit round the earth. Normally, a massive lump of rock like that would travel in a straight line, but becuase of the earth's gravitational pull, it stays in orbit. Soap bubbles are so light that this pull works even on substantially smaller scales.

Geez... that's blooming intellectual - and it's not even 10am on a Sunday morning yet.



Incidentally, the skin of a soap bubble is 10,000 times thinner than the breadth of a human hair.
