All those things you’ve been told? They’re not true.
Water drains down sinks anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
Nope, it doesn't. The Coriolis effect does make cyclones spin different ways on each side of the equator, but in something the size of a sink it has no effect whatsoever. Instead, it's all about which way you pour the water in.
There's no gravity on the International Space Station.
Earth's gravity is actually only a tiny bit weaker up on the ISS than it is down on the ground. It's the constant state of freefall caused by the space station being in orbit that gives astronauts (and everything else) their weightlessness.
