The Coriolis effect does Not affect the way water spins down the toilet, the plumbing and design of the toilet have the primary effect on way the water flushes down.
Coriolis effect determines the spin of hurricanes and weather systems. Low pressure systems spin counter clockwise in the northern hemisphere as do weather systems on Jupiter.
That stadium in Brazil is situated on the equator but the equator doesn't exactly bisect the stadium according to WGS 84 coordinates.
The Canada - U.S. border is supposed to be at latitude 49 North however at the Peace Arch crossing south of Vancouver, the Americans cheat lol.
The Peach Arch monument and the smaller markers near the vehicle lanes are actually 400 feet north of 49 North. I measured it with my GPS.
Zero Avenue in Surrey is also north of 49 parallel. There is a ditch beside Zero avenue which represents the boundary. The Americans built a cable fence on the U.S. side of the ditch cause some vehicles were actually driving thru the ditch to get onto the U.S. side lol.
The international boundary cuts north and south of the 49 parallel all the way out to the Great Lakes.
Windsor, Ontario bordering Detroit is the farthest south city in Canada at 42 degrees North. So when they say the 49th parallel, that only represents part of the continent.
The Americans still want to hold onto Point Roberts, they don't want to give up any land south of 49 parallel even though Point Roberts gets all its utilities from BC.
There was no GPS when they determined the 49th parallel boundary however its still amazing the degree of accuracy they achieved back then in surveying the border.
