from my own little investigation i think it does but i have been told it is not true and can be affected by piping, true or not?

Yes it does and was demonstrated on the Long Way Down whilst they were at the equator.

Only for huge sizes of water/air. The effect is real but it is irrelevant at sizes less than 1000km or so.
For all practical purposes you can forget about it and any TV demo done near the equator is trickery done by pouring the water to one side of the container. Next time you have a bath ort drain something down a hole try giving the water a swirl by hand first, you can easily make it swirl in either direction wherever you are.

In theory yes, in practice no. The effect is caused by the observer not being in an inertial frame (you're in a rotating one). However other effects such as currents set up by the water being poured and the shape of the vessel overwhelms the effect. I have just managed to change the direction of rotation in my sink, just to prove the point .

It is 100% true.
I have been on the Equator in Africa. I was passing through a village where the kids would show you how it work for a small charge.
They had a bucket of water with a hole in the bottom. They make you stand one side of the Equator and the water leaves the bucket clockwise.
Then they get you to stand on the other side of the Equator, and the water leaves anti-clockwise.
The best bit was to come...they then get you to stand right ON the Equator and the water just falls through the hole and goes straight down. It doesn't go clockwise or anti-clockwise.
It was brilliant! One of the best experiences of my life :o)

The official studies say it's inconclusive wether rotational innertia ( the effect of the earths rotation) actually exists. and yes, it can be affected by many factors such as the piping (which makes it pretty difficult to study in general).

I did that experiment when I went to Peru, no it's not true.
all the B-Daes and toilet waters ran the same as it does in the northern hemisphere.
I was hoping I was right too.lol

No, myth! Check out Snopes, or Phil Plait's 'Bad Astronomy' web site for a debunking and a good explanation!

The thing about the tourist stops is that they have a device to make it do that so they can get peoples money for believing everything they hear. It's completely false!!

It only goes down a plughole in a different direction, and it's due to the gravitational pull of the earth. on separate sides of the equator. Don't ask me what happens on the equator, i've never been on that line of longitude.

Yes it does. Ewan McGregor demonstrated it (On the series "Long Way Down" when they were at the equator. On one side, the water went clockwise, on the other counter-clockwise, and on the equator, no movement. Was so cool.
