You too can help support me and be part of such cutting-edge fictitious research and development. https://www.patreon.com/standupmaths CORRECTIONS - At 14:13 I say the mass "of the submersible" when I should be talking about the mass of water above the submersible. -At 31:34 I say "grams" instead of "kilograms". Which takes some of the air out of my unit bashing. - Let me know if you spot any other mistakes!
