So basically you can pass elk meat through a fence
All I really took from this was that ice skates have knives on the bottom of them essentially. It would make a pretty interesting killing tool in a crime novel or something where they can't determine what exactly was used. It was the jealous ex-wife who was a pro ice skater the whole time!
Ice skating is possible because of ice
So when Neil speaks of the ice skate on a bead of water..
I got to thinking, do some shoes on ice grip better than other?
Flat/smooth bottom dress shoes or boots might not grip as well as a running shoe with many groves according to the fence/ice block experiment?
Then I got to thinking,
If a shoe with more grooves, or "sipeing" cut into it grips better, then what about tires on ice…
I already knew that the more sipeing grips better, but on dry terrain the friction is high and chews those tires up quicker.
But for max grip on ice how far can you go with grooves?
Like the fence trick, ice will melt under the pressure contact of the touching parts, but does the water have time to turn back into ice in the cracks and grooves, or does it simply just channel the water away from the contact points?
I call bullshit on the squeezing ice.
Is it really melting because you squeeze it, or is it melting because of the transferring of body heat?
