| In a similar vein, get a balloon with just slightly inflated so it is small, get another which is well (but not fully) inflated and a short piece of plastic tube then join the two together. What happens goes against what you'd expect (well, what I expected at any rate). I would have thought the big balloon would have blown air into the little balloon but it doesn't, it sucks gas from it making it smaller and the big one bigger.
This I am told is what happens when you get a bend, the big bubble feeds off any little ones, something to do with small bubbles having more energy than big ones so the driving force goes the opposite way from what you'd think.
