[00:00] Why do you land in the same spot if you jump inside the train, but not if you jump on top of a train? - But first, let's see if we can glean any clues from this small scale test with two Lego guys, but
[00:14] Here we go. Now because this test was in water, you intuitively sort of had a sense the top guy would
[00:26] Well yeah, cause the top guy would have to travel through all that still water and that would push Whereas inside the train car, he's enclosed, so everything in that car, including the water is
[00:39] And just like water, air is also a fluid. And that's why inside the train when I jump, I get no pushback from all my air molecule neighbors But on top of the train, it's a whole different story.
[00:54] I'm continuously bonking into a mad rush of trillions of air molecules every second as I whiz by. So if I jump now, it makes total sense why they would push me back and I would land in a whole different spot.
