I see you are no longer posting about ice and water conductivities :-)

Tell me, Nick, do you *really* believe ice is a better heat transfer agent
than water?

I agree with you that a spinning can in an ice water bath will cool faster
than a spinning can in a container of cubes with no water, but you wrote

... water is a better conductor of heat than ice,

which is incorrect. Water has a 0.596 W/mC conductance, vs 2.26 for ice.

It's fun to watch you wriggle when you're wrong :-)
