Aperture Science Weighted Storage Cube

The Aperture Science Weighted Storage Cube is found in Test Chambers for a few of uses. It can hold down buttons, shield yourself from turrets, or make a platform out of it. You could also use it to prevent doors from closing but is not one of the initial uses. In Test Chamber 17 you are introduced to the Aperture Science Weighted Comanion Cube. Instead of an Aperture logo it has a pink heart and glows pink. It is needed to complete the test chamber and in the end is destroyed to move on.
