Jacob's Ladder Puzzle
Jacob's Ladder is a centuries-old traditional wooden puzzle. Grasp one end by the edges, turn the block over and watch the blocks "cascade" downward in a series.
Each of the wooden blocks makes a satisfying click as it folds downward and strikes the block below it. The blocks can also be manipulated rapidly back and forth by holding one end in each hand.
