      Wouldn't 'Let's go get smarter together' or 'today' or something of the likes be a bit more appropriate, due to it being an instance of becoming smarter rather than a culmination of instances at once? I feel like 'let's go get smarter every day' for one specific instance of becoming smarter is a bit misplaced and misnomed in comparison, and leads to a moment of awkwardness in my mind; as if it's advice, rather than a welcoming invitation. Maybe it's a solo perception, but here's to hoping this mention of insight can provide some benefit. Cheers, Destin.

    Before anyone says "We should just use CO2 scrubbers to reverse climate change" - CO2 scrubbers takes a LOT of electricity to run. Also, you are just capturing the CO2, not getting rid of it.

    I did electrolysis for a science fair project (testing the effects salt had on speed) and decided to take a sniff of the "oxygen" side, during a run with saltwater. Didn't even clue into the fact that since the house smelled like a pool something might be up. 😬 Glad I had the sense to step outside immediately into the fresh air as my airways drastically restricted! Needless to say, I stopped experimenting for the day!

    As a retired U.S. Navy anti-submarine and multi-sensor specialist, I can assure you that all our nuclear subs CAN break through the ice to "get fresh air". Mainly they must have this capability to launch ballistic and guided missiles. They also have the ability to release "sensors/transmitters/receivers" that can break through the ice when necessary. The technology on our newest boats is mind blowing indeed. Just wait until you see the 6th gen fighters and bombers!

    O2 partial pressure of 153 torr is normal where I am, but obviously the ambient pressure on the sub is higher so you'd be aiming for what? 160 torr? 200 torr would be a fire hazard.

    Flat coke still has CO2 in it, but it has the same amount of CO2 as the atmosphere whereas the fizzy coke has an excess amount of dissolved CO2 and it needs to escape and equalise. This is why coke doesn’t fizz before the bottle is open. And this is known as Henry’s law for anyone interested, it’s one of the gas laws.
