Edgeless Safety Cube

"You have no idea how tiring it is to praise someone for placing an Edgeless Safety Cube into a receptacle designed to exactly fit an Edgeless Safety Cube."

- GLaDOS

The Edgeless Safety Cube is a testing element used in the Aperture Science Enrichment Center. It is used primarily in the cooperative campaign of Portal 2. Despite being a sphere, it is still called a "cube".

Overview



 * The Edgeless Cubes serve the same purpose as the Weighted Storage Cubes, thus opening doors or activating platforms, except that they must be placed in a circular receptacle instead of on a Super Button.
 * Edgeless Cubes can be used to depress the Super Buttons, but tend to roll off if not held there.

Behind the scenes



 * The Portal 2 Edgeless Safety Cubes may be related to the "Weighted Storage Ball" seen in the advanced Test Chamber 17 in Portal and reusing the Personality Core model seen at the end of the game, but it has yet to be confirmed.

Trivia

 * The Edgeless Cube appears is blue when neutral, and turns Yellowish-orange when activated in its bucket, just as the Weighted Storage Cube does when placed on a button..
 * It appeared only once in the single player campaign of Portal 2, possibly as a small easter egg during the Advanced Aerial Faith Plate chamber.
