They are also notably smaller in size than in Portal. In Portal 2, the cubes have a circular blue light on each side, and when left on a button it changes to a yellow light. Like most objects, the Weighted Storage Cube will disintegrate upon touching an Aperture Science Material Emancipation Grill.

The Weighted Storage Cube can also be used as a makeshift weapon against an Aperture Science Sentry Turret by dropping it on the Sentry Gun from a Portal, or as a makeshift shield to block turret fire and energy pellets. It can be picked up by using the "use" key and can also be taken through portals. Weighted Storage Cubes appear either via an Aperture Science Vital Apparatus Vent or are already in a test chamber. The Cube was also Doug Rattman's partner. In the cooperative campaign of Portal 2, the Weighted Storage Cubes are to be placed on Cube Buttons. In Portal and the Single Player campaign of Portal 2, Weighted Storage Cubes are to be placed on a Super Button to allow Test Subjects to advance. The Weighted Storage Cube is a device used for solving cube-and-button based puzzles in the various Test Chambers found throughout the Enrichment Center.
