I did not know about the term “cat ice” for the ice on these “crunchy” puddles. The 1901 book excerpt that is briefly shown in that video gives the definition, but does not mention why cat is in the term. Online, the Merriam-Webster dictionary also gives the term “shell ice", and one twitter poster (@RobGMacfarlane) writes that the ice is just thick enough to “support a cat” and hence the term.

About that Prof. Lewin video, if you look to it for an explanation, then you can better use your time elsewhere–you will find no explanation there of any freezing phenomena.

Unfortunately, we haven&#8217;t had a frost day in weeks, and we haven&#8217;t had much sun either, just the usual NW winter rain. In Japan, we would often have both frost and sun. </p> <p>Nice to hear about the grandson. Would like to see you guys together, reading about snow or otherwise. </p> <p>Jon </p> <p> <br /></p> Hi Andy,
I bet you miss the ice and snow sometimes! Unfortunately, we haven’t had a frost day in weeks, and we haven’t had much sun either, just the usual NW winter rain. In Japan, we would often have both frost and sun.

Nice to hear about the grandson. Would like to see you guys together, reading about snow or otherwise.

Jon
