Re: misconception re ice melting under skates

Whoa! Those are two very different phenomena. One does not skate on
ice at melting temperature.

I don't think there is any doubt that the phenomenon of regelation
accounts for the wire cutting through the ice cube. After all, that
phenomenon occurs in a saturated water-ice environment. Only a small
pressure is needed to produce melting, and clearly the process of
refreezing (regelation) does take place; the ice is not cut.

And under the skates? Crawford
