Every time XKCD says, "Let's ignore physics": "Welp there goes the planet."
I had never realized/internalized 0:48 “water always wants to boil but is held together by air pressure”. Amazing, small change in perspective makes things like evaporation now obvious!
My 7th grade science teacher one time flippantly said "you couldn't put the flow of Niagra Falls through this kitchen faucet" and I've been thinking about that weekly for the past 30 years. Can't believe XKCD of all places hammered this question directly on the noggin! I feel like a part of my brain can finally rest. Thank you!!
I actually cannot put in to words the amount of thanks I could give you. You saying "Water always wants to boil, but is held down by air pressure" just clicked. I never really understood why water boils in a vacuum but that simple explanation just made it all click. Thank you so much. Great video as well.
cant believe this didnt end with "one would be in very, very hot water"
3:23 Given energy output projections, that may well be the actual last ever straw
You forgot the "committee angered" vs. "worlds destroyed" graph from the book, that was so awesome!
1:28 To be fair, the whole of Niagara falls shooting out in a 10-meter across jet stream is already insane
3:24 without context is great
I mean, the number of committeemen angered is bigger than the number of planets destroyed. Let’s worry about the bigger number first.
I.. Did not expect this to end with "power output of a small star"
You underestimate the power of those nice metal straws you can get
"If you try to make water—which is pretty heavy—go that fast, it tends to start ignoring the turns in your pipes" has always been one of my favorite XKCD sentences and I was excited to hear it read out loud :'D
0:10 Reminds me of the people's front of Judea 😂😂
Earth Getting Destroyed: Collateral Damage Getting Sued by Multiple Organizations: WE CANNOT DO THIS
Ah, of course. We all die. Again. I love that almost all of these "What if..." physics questions usually end with "... and we destroy the Earth via catastrophic energy release!"
I really liked the joke from the print version where there's a graph showing 5 committees angered and 1 planet destroyed, so they say, "the first number is bigger, so it's probably more important."
Things went totally off the rails after this of course, but the water ignoring curves in the pipe moment at 1:49 reminded me of the scene in Indiana Jones and the Temple of Doom where the water is flowing so fast through the mining tunnels that it causes long strips of rock to blast out of the cliffside.
When it comes to physics thought experiments, there are few opening sentences more exciting than "well, if you did that, it would have the power output of a small star".
