Toilet water: clockwise or counterclock-wise?

I apologize for this silly question. My
nephew asked me this question and
I didn't have an answer. I believe
the toilet water goes down in the opposite
direction when you live in the souther
hemisphere, correct? I realize the toilet
water on planes doesn't exactly act like
household toilet... but if it did, which
way would it flow... and does it change
direction after the planes flies to the
other hemisphere? (LAX to SYD,
for example)

Planes dont have toilet water. When you press the flush button a vacume sucks everything out. However, on older aircraft a blue liquid is released and it just goes straight down.

That was an interesting question Bobcat; not silly at all.

Although the toilets on planes do not act like their cousins on the ground, the sinks on the a/c do.

If you had a sinkfull of water while you were over mexico, it would not go down the drain in the same direction as it would if it was flying over Brazil.

Actually I have noticed the blue water does swirl in some aircraft, but this is probably more because the water is deliberately angled, rather than the act of gravity and the earth's spin.

This is an urban legend, you guys  Smile

(want to calculate what the Coriolis forces are, in water in something the size of a toilet bowl, even at "max effect" Mid-Latitudes? They're pretty tiny, you'd be waiting a looong while --and would have to have the water real still, impossibly so, in fact-- to see it swirl down due chiefly to that effect)

Mark, no it's not, haven't you seen the Simpsons episode when they go to Australia??  Big grin

Seriously, I've also heard that this business about the water swirling clockwise or anti clockwise depending on northern- and suthern hemisphere is an urban legend.

I was under the impression that it did swirl depending on where you are. I distinctly remember seeing Michael Palin doing an experiment either side of the equator....

well I'll give you info on my AWACS. Most know we are based on the 707 airframe and we have one lav in the back. This has the blue treated 'water' in it. Mostly we do not flush, because believe it or not it mucks up the system. The 'flusher' chops up what is in the tank and just releases it back to top of the bowl. The blue water just falls straight down into the hole. There is also no water tank for the sink so we don;t have water either. We do not have flappers on our toilets so it is funny to screw with the new guys and 'blue ham' or blue ass' them. When we know someone is in the crapper the plane dives so the blue 'water' smacks them in the ass  Smile I've also been in some combat decents where afterword I've seen the blue water on the ceiling. Very nasty

The best is when we convinced this Army General flying with us that the Radome actually flew off the plane then came back and reattached when the mission was over.  Smile We even dove a bit when we planned for 'Saucer seperation' and we jinked the plane a bit again when the radome ' came home'.

Probably depends on whether the flusher is left-handed.

Anyone in the souther hemisphere
right now? I never thought I'd ask
this, but would you do us a favor by
flushing your toilet and see the water
is clockwise or counter-clockwise?


Thanks!

The way that the water flows out is determined more by the way that the container is tilted or the way that it was filled. Corialis effect has almost no influince over the way that a toilet is flushed.

Toilet water direction is a myth.

As a side note, the thing that does change from Northern to Southern Hemisphereis is color CRT tubes. The slightly different vertical magnetic field component is more than enough to destroy color quality. Southern hemisphere CRT tubes are Northern Hemisphere tubes upside down. (Try turning your monitor upside down). To compensate, aircraft have expensive electronic CRT compensation systems, which make LCDs a bargain.

I live in NZ Bobcat and I just did what you said.
Unfortunately my toilet doesn't have a "swirl" type flush; it comes from all directions really fast so it was hard to tell.  Crying

Hey Lt-AWACS,
That saucer prank sounds like a classic!
I would've been in tears if I was there.  Big grin
