    Not super sciencey, but there's some cool slow motion video of skate blades interacting with the ice.

    Cool video. The host had an engaging manner, and brought out a number of cogent explanations to complement the excellent photography.

    One thing I expected to see, but was probably omitted for brevity's sake, was a description of compressional (as well as frictional) melting of the ice. Water ice expands as it freezes; if pressure is applied to ice the reverse happens, leaving a film of water atop it.

    Is that film considered chilled agua?

    There was a bit of discussion around that in the Reddit thread I found the link from. Nothing too substantial though.

    I was kind of surprised that the skate blade is going in a circle for the figure skating spins. I always thought it was rotating on a small portion of the skate blade.

    Rex is my uncle. One of the most interesting men you will ever meet, and written some great articles throughout his career.

    A great man to just sit and talk with. Especially because he brings at least 3 growlers of San Diego brews to every family even.
