Why is ice so slippery ?

The answer lies in a film of water that is generated by friction, one that is far thinner than expected and much more viscous than usual water through its resemblance to the “snow cones” of crushed ice we drink during the summer. This phenomenon was recently demonstrated by researchers from the LPENS, Micromegas team, with support from the École polytechnique, in a study that appeared in Physical Review X on 2019, November 4.
