A tray to help make awesome & perfectly square ice cubes.
Technically they'd be called cubes, as squares are only two-dimensional. So really, standard ice cubes aren't ice cubes. They're not cubes at all, they're little slices or something. Anyway...
This tray makes companion ice cubes so you'll never be alone again! It is certainly a triumph of science. Could also make chocolate if you so desired.
These ice cubes will not burn very easily. Technically these ice cubes are only companion cube-shaped on 5 sides. So you get one flat side. Science hasn't quite figured out how to make a perfect Portal 2 companion ice cube just yet, but maybe someday soon.
