Your mother always told you not to play with your food, but I think she'd make an exception for the Rubik's Cube Spice Shaker. That's right, the uber popular puzzle cube has been turned in to a salt and pepper shaker.
The Rubik's Cube Spice Shaker can be set to grind either coarse or fine spices with the top part of the cube acting as the grinding mill. The one major downfall of this design is that it can't be used as an actual Rubik's Cube. Still, it is a fun and clever way to mix up the monotony that is shaking salt and grinding pepper.
