Hello. I think that you know an experiment called Cartesian diver. I can use some heads of matches like Castesian divers like there: I know how it works. However, I don't know why the heats of matches don't go down in some moment, but first one, then second with bigger force, then third with bigger force. The pressure is on each places same, yes? So, every heat of match suck same number of watter to poores of wood. So, why they don't go down in some moment? What decide about order of matches? Thank you very much.
