Instructions
Form a single strand of all 216 balls. Do this by pulling one ball away from the group and allowing the other balls to follow, forming a long strand.
Start at one end of the strand and count six balls. Fold the strand after the sixth ball, allowing the six end-balls to line up perfectly with the next six balls on the strand. Make sure the balls don't interlock but instead sit directly next to one another.
Fold the strand again, allowing the next six balls to line up perfectly with the previous six balls.
Repeat Step 3 until you reach the end of the strand. You should have a two-dimensional rectangle measuring six balls by 36 balls.
Start at one end of the long side of the rectangle, and count six balls in. Fold the rectangle on top of itself after the sixth ball, allowing the balls to line up directly next to the neighboring balls. Do not allow the balls to interlock.
Fold the rectangle on itself again as in Step 5, creating another layer to the emerging cube.
Repeat Step 6 three more times to finish the cube.
