Cube Tube

No, the Cube Tube is not some competitor to YouTube. Rather, the Cube Tube is just as its name says it is. Literally, a tube, like in test-tubes, for cubes, like in ice cubes.

Most conventional ice cube trays are rectangular and create a lot of problems especially when you only need just one ice cube, and what about the careful handling when filling it with water and transporting it into the freezer. Cube Tube solves that problem. Its vertical orientation means zero spillage as you carry it into the freezer. Also, because of its tube structure, you can pull it out to release one ice cube at a time. There's actually no need to get another container to contain all your ice cubes if you are using a conventional ice cube tray. The pictures below should probably give you a better idea of how it works.
