I used to think so until I realised that air and water are both fluids, except air is thinner.
To be clear to anyone with minds being blown: air is gas and gas is a type of fluid. Water is liquid and liquid is also a type of fluid.
that goes a long way in explaining some of those farts.
Exactly. Ever skip a stone on the surface of a lake? It's like that, except it's a continuous skip, with air instead of water, and you're inside the stone.
That's a bad analogy.
It was a joke.
That's an awesome analogy.
I would be equally amazed to see something denser than water swimming.
Mythbusters has an episode where they swim in non-newtonian fluid
Ok, you have my attention, going googling.
That was interesting: https://www.youtube.com/watch?v=-wiYtoG9kZE
Like a submarine?
Submarines work by manipulating their density, don't they? Then they just float at whatever level matches their density.
Yeah, they're more like dirigibles than airplanes. But same as airplanes, people have had a hard time believing that something made of metal can float.
