[time-nuts] synchronizing a large number of weaklycoupled oscillators

My *guess* would be that you would need to setup a situation that favored
the lock. Simple outflow clocks probably aren't going to lock. Any of the
escarpment designs have the potential to lock. 

Past that, sounds like a good reason to build up some on a flimsy shelf and
see what happens.

Oooh.  Clepsydra  (is that also the plural?).. one of my favorite topics..

It never occurred to me that they might couple, although almost every
other mechanical clock does.

What would the mechanism be?
How could one set up an experiment?

(hey, it's getting to be summertime, and my kids need projects that 
might get them wet)
