This is a video of filmmaker Mitch Bergsma demonstrating how to make a pair of bubble goggles with just your hands that you can use to see underwater. Plus you can use air exhaled from your nose or mouth to refill your bubble goggles in case some leaks out. They work too, I just tried it in the toilet and my phone was definitely in there.
Keep going for the video demonstration, complete with him farting underwater at the end because this is the internet.
