The way a glacier forms is you have the snow, it densifies over time. And in that process, air gets squeezed out. You start to lose the kind of white fluffiness aspect of snow. It starts to turn into something that looks a lot more like ice.
What makes ice slippery? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly uncover the complex physics of ice and cool facts we’re still learning about it with physicist and author, Laurie Winkless.
