Emily wants to improve her curling game. She learns that friction can be a friend. The curling rink ice is sprinkled with small drops of water to create ice pebbles; these raise the stone from the ice surface, reducing friction and helping the stone slide more easily. Curlers sweep the ice in front of a stone to warm the ice and also reduce friction. Pro curler, Abbie, and world champion, Andy Ormsby, demonstrate their strategies and techniques. Also includes a brief history of curling.
