Rotor Tubes is a Mini-game in LittleBigPlanet's Story Mode. In the minigame, you must make it through rotating tubes. So time your jump and hop on the first. When it goes up, run to the top with it and jump, and land inside it. Continue. Note: Don't Land on the top or you'll lose, unless you get back in the middle of the next tube.
With some careful use of the leverage of a spinning tube, it is possible to launch your sackperson onto the snowy hills in the background, allowing you to simply bypass the whole level. This makes for an easy ace.
