Curlers sweep the ice to help the stone travel farther and straighter. Sweeping in front of the stone reduces friction and helps the curlers control the amount of curl the stone undergoes.

Does sweeping make a difference in curling?

In the game of curling, sweeping is critical. It's what changes the path of stone after it's thrown down the ice. Sweeping works by warming up the ice and reducing friction, which makes the rock curl less and therefore move straighter, says Shegelski.

Why do they sweep the floor in curling?

The basic principle behind sweeping is deceptively simple. The heat produced by the friction generated by sweeping melts the ice and produces a thin layer of water over which the heavy granite stone slides more easily since the friction between the stone and water is less than that between the stone and ice.

Does sweeping speed up or slow down curling?

The stones curl more as they slow down, so sweeping early in travel tends to increase distance as well as straighten the path, and sweeping after sideways motion is established can increase the sideways distance.

Can anyone sweep curling?

What makes a curling stone curl?

When the stone is set in motion, it is also made to rotate slightly, and this rotation causes it to curve, or curl, to one side or another. If you're the thrower, you can aim your stone to block your opponents' stones, knock them out of the way, or even slide around them; own the curl, you own the game.

Why is curling ice bumpy?

The reason the ice has bumps and the reason the teams sweep the ice in front of the stone are both to control friction and control the curl of the stone. Adding bumps to the ice is known as pebbling. Ice technicians sprinkle two layers of water droplets on top of the ice that freeze to form two heights of bumps.
