The wooden snake cube puzzle is made up of a long wooden chain of 27 "cubelets." By intricately bending placing and building the cubelets on top of one another you can create one solid cube. Each of the 27 cubelets is connected to one another with an elastic band on the inside to keep the cubes together but still bendable. When finished you'll have a 3-inch by 3-inch by 3-inch cube.
