Hi again,
I located this question on the internet:
"How come you can't take one canister of hydrogen and one canister of oxygen and spray them at each other to make water?"
www.Newton.dep.anl.gov/askasci/chem99/chem99148.htm
Now there may be a clue in a typo I made but corrected: I first typed "spray then" but "corrected" it to "spray them".
I once heard a music expert being interviewed (Brian Eno) who had this idea "honour thy error": if he made a mistake he would take another look as it just MIGHT open up a new perspective. Then again it just might not help much.
However in this case I can dream up an idea: "then" leads me to ask: who goes first?
If spraying hydrogen and oxygen at each other: who sprays at who? Does the oxygen have a jump-start on the hydrogen, or vice-versa?
One of them has to have a head-start? Or do they both combine with equal velocity from equal positions? But that would mean they were already combined in a third party that defined them as equal? Because what does "combined" mean if not "sharing"?
So we seem to have an "alternatives" barrier to getting this show on the road. How to overcome this barrier?
Well: we need a spark: a bright spark to break down the barrier; break the ice as it were. How about we add some heat: have the hydrogen and oxygen move out of their comfort levels by experiencing some externally-sourced influence; now they start bouncing off each other and juggling this third influence.
Suppose someone is juggling balls and you bump into them. Consider this juggler juggling balls "makes water" (metaphorically) (keeps his "liquidity": doesn't drop the balls) after you bump him, by speeding up his juggling act.
(Why would he speed up his juggling act just because you bumped into him? If you gave him another space to juggle in (a hyper-space); he could categorise his list with it (so in the case of hydrogen and oxygen you could lower the energy (the alternatives) barrier by providing a hyperspace to keep track of things (like providing another juggler to share the load). Solid platinum is a catalyst here I learned; it gives hydrogen and oxygen a "chat room" to get to know each other (to "break the ice"; lower the energy barrier).
What if you bumped him in such a way as to speed him up? Now the bump is hidden in the heat (hidden variable!)(Bell inequalities: he is "ringing" like a bell you might say: ringing the changes)
He is now effectively juggling the balls AND the external influence (from when you bumped him), but that influence is hidden in "ringing the changes".
If this juggler was occassionally swapping balls with other jugglers, you could get a chain reaction and eventually the external-influence of you bumping one juggler, could become very diluted in the exchanges spread over many jugglers.
("Jingle bells, jingle bells; jingle all the way. Oh what fun it is to ride on a one-horse open sleigh!")
Overall the liquidity (ability to carry on juggling)(The one-horse open sleigh if you work/play? with the metaphors here, using your imagination) of all the jugglers could be maintained with just a slight increase in their overall speed ("temperature" concept here).
If they could find a ready means to give off this heat they might transfer it back to the external world; then the fact that you disturbed one of them becomes just a memory, encoded into the large-scale structure of groups of balls spread among the jugglers.
Your collection of jugglers is effectively now a Bose-Einstein condensate; as they now all share the same meeting state (quantum state) as the beginning (you bumped one of them) and the ending (they collectively bumped you: i.e. gave you + outside world some heat) are what contains them. They now know you ("We
've met before: you bumped into me, and we juggled that bump and gave it back carrying knowledge about our society of jugglers" you could imagine this Bose-Einstein condensate saying)
The answer given at the web-site does say that there is an energy barrier, that the hydrogen and oxygen need added heat or a catalyst to get the reaction started.
Once a couple of molecules are kicked over the barrier the H2 and O2 molecules can break apart and form H2O.
