How it's madeEdit
This little cubie is made from a corner cubie of a regular Rubik's Cube. First you need to cut off the part of the corner that makes the cubie be able to turn with the cube. Next you need to fill the empty spot with apoxie sculpt and mold the sculpt into the corner of the cubie. After the base is done just apply stickers and you have a 1x1x1 Rubik's cube.
Solving the cubeEdit
The 1x1x1 is currently the hardest cube to solve, due to it's enormous size and the amount of steps that lead to its solving. To get a professional's instruction, watch MeMyselfAndPi's solving video.
