Wow! Really, I have never thought about it like this. It's awesome that natural occurrences have scientific undertone.
If I were asked, I would have concluded that it's the pressure exerted by our weight (which would lead to the process of regelation in the ice) that causes ice to be slippery.. and I would've failed it :(
Now I know better. Thanks for sharing
Science keeps bringing us facts over fiction :)
If you can imagine the outcome of a lot of events without science showing us the real state of things; it will be as chaotic as anyone can imagine.
