All submarines are strange. it's easy to imagine them as nuclear-powered sea monsters, circling the globe forever underwater. But some are weirder than others.
Take, for instance, this sub a guy built himself. It doesn't look quite like your average sub, more like a carbon fiber kayak with a stealth fighter canopy. Moreover, it's strange because it was built just for shits and giggles. It must have been a hard engineering exercise, making sure it'd keep from sinking under the weight of the designers massive balls (presumably that's what you need to seal yourself in an underwater coffin of your own design).
Still, there must be weirder submarines in existence or in history. Which one is your favorite?
