The Rubik's company has a veritable cornucopia of Rubik's cubes and similar puzzles. This is a tutorial video series which will show you how to lubricate a Rubik's Clock. It's important to BE VERY CAREFUL while breaking the glue. It is very easy to cut yourself while doing this. Also, once you open your clock it will be obvious that you have done so, so keep that in mind if you intend to sell your clock.
