Q & A

Q. What makes ice slippery?

A. It's very easy for the top layer of ice to melt. And it's that layer of water on top of the ice that makes it slippery. For example, ice skates will push down on the ice, and because of their pressure, they will melt the ice. When water freezEs, it's usually pretty flat because the water was flat to begin with. If a surface can absorb the water, it won't get slippery. That's why sand and raw wood don't get slippery.
