[Portal] Why is it called a "Weighted Storage Cube"? What does it store?
gpt
Aperture Science uses over engineered, wasteful, science-y everything. It's just the way they do things. A weighted storage cube is simply another way to say, a crate. Whether there's anything actually inside is up to speculation, probably something expensive and unnecessary as usual.

The most likely answer is that it's specifically designed as a counterpart to the 1500 Megawatt Aperture Science Super Colliding Super Button, and its cube-specific version. Just for testing, at least originally.
