Pencil Pop
A competition where 2 people take turns taking hits on each others pencils in an effort to break them. 1st person to break the other one's pencil in half wins. The defender holds pencil between thumb and 1st finger of both hands like a karate board. The attacker holds their pencils (eraser end) with thumb and 1st finger of one hand, and the thumb and middle finger of the other hand on the (writing end). The thumb should be slid further up on the pencil to push down, this generates the downward swing force to break your opponent's pencil. (Snap your fingers and while holding that position after the snap make a pencil touch your middle finger and bottom of thumb with the thumb pressing down make the pencil snap forward)
