I've ice skated at -30/35C, so I call bullshit!
Not quite as sharp as a knife, ever cut yourself on skate blades?
Why does the way ice melts matter???
As a Canadian with 25+ years playing hockey on outdoor rinks, I can tell just how much temperature is a variable for quality ice. To warm and it’s soft and you catch an edge and fall on your face, to cold and the ice feels brittle under your skates like it’s breaking away as you try to push on it
liquid water doesnt exist at any pressure under -20 degrees celsius. There must be some another phenomenon to ice skate.
