Portal 2 Companion Cube Ice Tray

Portal 2 Companion Cube Ice Tray

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.
