It's the promised bonus footage from my "The Deepest Maths Video Ever [pressure vs depth]" video. https://www.youtube.com/watch?v=-tGusgPTSm4
Always check your units! It's just good advice for life. So when I realised during the video I had not double-checked the units of P = gρD I decided to film myself doing so as bonus footage. This is also a behind-the-scenes view inside DSV Unrealistic.
Warning: My iPad was not recording for the start of this video (or rather: it was recording for an unknown period of time before it stopped without saving). But I notice before it is too late.
PS For anyone who wanted a copy of the artist impression I had commissioned for this video, you can download it in full-res here: https://www.dropbox.com/s/qi5qb2ee8v3i31r/ARTISTS-IMPRESSION.png?dl=0
