Ker Plunk*

This classic dexterity game can be learned in seconds but offers a fun test of hand-eye coordination that challenges people of all ages and skill levels. The game consists of a clear plastic tube, 30 thin sticks, and 32 marbles. Players insert the sticks through the tube and pour marbles in from the top, then carefully remove the sticks one by one without letting any marbles fall. The player who collects the fewest marbles at the end wins.
