Chalking a snooker cue. Close-up high-speed footage of a piece of 'chalk' (actually a silicate-based powder) being applied to the tip of a snooker cue. This material increases the friction coefficient of the tip, making it grip the cue ball better, helping players to impart spin when striking the cue ball. | |
