DURING THIS STEP YOU CAN NOT MOVE THE WHOLE CUBE IN ANY WAY
YOU MUST NOT USE THE SAME MOVEMENT IN THIS STEP MORE THAN ONCE IN A ROW OR IT WILL DESTROY THE CUBE.
if you want to turn the corner clockwise use picture 1
if you want to turn the corner counterclockwise use picture 2
here is an example of how to use this step. after you do one corner turn the top slice to the next one see if you have to turn it clockwise or counterclockwise if you turn it the same direction as you did the last time it will not fix the cube so make sure you don't move it the same way twice.
so just dont use the same pattern twice in a row and don't turn the whole cube.
