105: Ice, Ice, Baby: Why Is Ice Slippery?

How does water turn into ice? Why is ice sometimes slippery and other times sticky? Why is it so cold? Why does it float? How are icicles made? Why are icebergs mostly underwater? What was the ice age? We’ll get answers to all of those questions with help from Celeste Labedz of the California Institute of Technology. And we’ll take a trip to the world’s largest skating rink, the Rideau Canal in Ottawa, Ontario.
