People use GoPros to film all sorts of stuff, from swimming manta rays to swimming races off Alcatraz. You could watch footage of people doing extreme water-based activities captured via GoPro every day for the rest of your life, and there would still be so much GoPro footage of people doing extreme water-based activities left unviewed in the world.
The bold iconoclast behind the YouTube account How To Make Sushi Japanese Food Recipes isn't going to risk toiling away recording extreme water-based sports in obscurity. No, they are instead blazing a bold trail through the under-tapped realm of food preparation cinematography, risking the health of their GoPro to capture footage of an egg being poached.
The result, as you can see, is footage of an egg being poached.

The mysterious auteur elaborated on their novel technique on Reddit, noting that the standard underwater case sprang a leak and did not survive the boiling process, and that the LCD screen went black and did not respond immediately after the experiment.
