So we're out here today in Lower Manhattan ice skating.
There are lots of kids skating around, dudes in hockey skates,
and I'm here getting my inner Michelle Kwanan.
If you really think about it, ice skating is just controlled slipping on ice.
And whenever I go skating, I can't help but think about the Winter Olympics,
like the ones that are happening right now in Italy.
Welcome inside the Cortina Curling Olympic Stadium.
The United States mixed curling duo of Corey Dropkin and Corey TC faces Team Canada in a matchup of unbeaten teams.
And watching the Olympics, I started to realize that if you really think about it,
so many of the Winter Olympics sports are just about controlled slipping on ice,
like bobsledding, the luge curling.
And yet, scientists still don't really know why ice is slippery.
Sure, they have theories like the pressure that we put on the ice,
maybe melty ice creating a thin watery layer,
but scientists mostly agree that those theories aren't the full picture.
The slipperiness of ice is actually still a mystery.
It's such a simple question that should have been answered centuries ago,
but turns out all the stuff we learned at school,
it's not fully correct like with many, many other things.
So today we're going to try to get some answers.
