Re: ice melting (was under skates)

to penetrate....

And so, never failing to plunge in where the wary fear to tread,
I offer you experimental results fresh out of the kitchen - in kitchen
vernacular units - no less!

Procedure: Take three sockets (normally used with a socket wrench)
each weighing 5 oz. (!) and tie one of the following on:
a nylon fishing line diam 0.010 in
a polycotton sewing thread diam 0.005 in
a steel piano wire diam 0.020 in

Apply each filament as a noose to a different 1/2 inch wide ice chip
in a 0 degF freezer compartment so the sockets hang beneath the ice chips
( through the shelf slats).

First Data Point
----------------
Wait 2 hours - no penetration by any of the filaments.

hehe...next week: why a warm water container freezes before a cool water
container ( Just kidding...)

Talk about naive experiments - looks like the target filament pressure
for penetration/regelation should be quite a bit higher.
And closer to freezing too...
