-nope, it won't.
It's just to small a system to be effected by the coriolis effect.

Well, if you plugged up most of the drain so it drained very slowly, the Coriolis force could eventually reverse it, given enough time. It affects all systems; it just is a weak force compared to the force of the rotation of the system.

If it drained very slowly it wouldn't build up any momentum for it to spin, right?
It would essentially be a system with water standing still. And you don't se still standing water starting to spin by itself just becourse you let it be for a couple of weeks, months, years...

I'm assuming there's some momentum to begin with. It wouldn't reverse the flow, but it would slow it down/stop it.

the bathtub should work. as a child i remeber playing in the tub. i would fill it up a couple of inches and drain the water and watch stuff get sucked down the whirlpool. i used to watch the stuff go round and round the vortex until it got sucked it. i was easily amused as a child.

Yes, but it doesn't involve the coriolis effect.
It depends on the shape of the bath tub, the position of the drain, the movement of water before it starts to go down the drain, etc etc.

If you take all the necessery steps and have a perfect vessel for the water and observe very closely you might be able to detect the coriolis force, but I wouldn't bet on it on your first attempt!

i read some articles and they explain why it wouldnt affect the bathtub. oh well, it was still fun to do as a child
