(But a little anti-rust might be a nice addition?) Ashton who wonders what's in the new Dex -ron? or -joe auto antifreezes, such that it need not be changed so often -?- and is kinder to the aluminum / Fe badness of the emf-series. (but not wondering yet enough.. to Google for it) PS - the ice-cube tray trick with hot water, has a prosaic explanation.. [cackle]

It reminds me of my freshman college physics course where the prof did a problem involving static and dynamic friction and concluded "always pump your brakes!" But that simple example of static friction being higher than dynamic friction neglects reaction times, people generally not knowing how to apply brakes to the limits of adhesion, etc., real-world factors that affect braking distances. Car and Driver magazine did an article on someone who ran a driving course who showed that in most cases, with most drivers, (in cars without ABS) that stomping on the brakes and locking up all 4 wheels gave shorter stoping distances than pumping the brakes. (I think we discussed it on ezIWeThey a while ago.) I suspect that what I saw in the hot water pipes freezing first is more related to air being in the hot water than supercooling, but who knows. It was about 25 years ago and I have no desire to repeat the experiment! :-) Cheers, Scott.
