While most hamsters spend their days trapped in a cage sitting around in sawdust, this little guy is exploring the depths of a pool in his personal hamster-powered submarine.

By taking a plastic bottle and putting in a hamster wheel, all the adorable critter has to do is go for a little jog on the wheel. The wheel itself is attached to a little propeller that sticks out that back and turns when the wheel is in motion. The hamster-powered submarine also comes equipped with air tubes that go to the surface so that the squeaky cute creature never runs out of air.
