Liquid chalk. A liquid version of the traditional block chalk that has been used to improve grip in weightlifting, climbing, and other sports that require grip strength.

The name derives from the texture of actual shark skin. Shark skin will allow a hand to move freely in one direction while halting the hand if it were to move in the opposite direction. Liquid chalk or sharkchalk goes on smooth, then grips.
Do you use block chalk or have you upgraded to sharkchalk yet?
