Physics:Could You Live Under Water?
I've often wondered whether I could be genuinely self-sufficient. It shouldn't be too difficult as long as I had enough land， but could I be self-sufficient in absolutely everything， even the air that I breathe? And that’s today's big question: could you live under water? I confess we use television trickery to pretend that I was in a giant underwater bubble， but by the end of this program I hope to be living at the bottom of this tank in an underwater version of the Shack.
