this iron ball, is to be dropped 10km under sea. btw, most ocean floor is no more that 4km deep. that 10km is about the deepest chasms, where unknown creatures lurk.https://twitter.com/CGTNOfficial/status/1074306904510337026

Why a iron ball? cuz else you gonna be crushed by a 1 mega ton anvil. A ball is, like, u can't crush an egg in ur palm. But does anyone know how to calculate pressure? say, you are at n meters below a 10mx10m swimming pool.#physics

@xahleeEach meter of water is about an extra 0.1 atm.So at 10000m you get 1000atm, or 14000psi.

@xahlee not me! but my first exposure to Bejan and constructal law was this article that pointed out fish, although bouyant, are constrained by gravity because water is incompressible and must be LIFTED ever so slightly as they move through it. https://www.sciencedaily.com/releases/2005/12/051230083922.htm

@alvarogonzalezsotillo that's assuming a swimming pool of 10 meter by 10 meter?

@xahleePressure doesn't depend on the size of the pool, only on the depth. Try to imagine the pool as a bunch of columns of water: you only support the water above you, the rest is supported by the ground.

@alvarogonzalezsotillo now it seems obvious! thanks!
