Sure, YouTube has lots of cute, funny, horrific, and otherwise diverting material to recommend, but every so often you come across a video so flat-out cool you have to rejoice that the platform even exists. This mesmerizing footage of an outing in a self-made, single-occupant submarine would certainly fit that bill.
Part of the allure here comes in witnessing a dude attempt something most of us wouldn’t try in a million years: trust his own nautical engineering. It doesn’t look as though the pilot, Olivier Feuillette, added much more than an airtight capsule and fin-like rudder to his kayak to transform it into what resembles a steampunk sea creature—but what else do you need?
Reddit picked up the clip, with users alternately wowed and worried by the claustrophobic, jerry-rigged vehicle, and many posing yet-unanswered technical questions. For now, enjoy Feuillette’s successful descent into some kelpy wonders lying just offshore, and maybe think about building one of these things for yourself.
