Water Closet (WC) is a toilet that disposes of the waste by using water to flush it through a drainpipe to another location. Modern toilets incorporate an 'S' bend; this 'trap' creates a water seal which remains filled the 'S' bend also provides siphon action which helps accelerate the flushing process. Water filling up the bowl creates a high pressure area which forces the water past the S bend. At the S bend when water starts to move it creates a vacuum that pulls the water and waste out of the toilet. When no more water is left then the air stops the siphon or vacuum process. At that point the water that is going into the bowl continues to fill up the bowl to equalize the bowl and the S bend. This ends the cycle of one flush. Since there were no rooms designated for toilets or crappers as they were called (named after John L Crapper, inventor of the flush toilet) the term Water Closet was coined as homes that had the out houses moved indoors were usually located in closets in the home.

Vicente,
"WC" actually is the short form of "Water Closet".
That's what the early Toilets were called.

WC = toilet. I wonder how many went and check.

"WC", huh? I haven't heard that word since I've moved back from Hong Kong in the early 90's.
May be I should try the knife edge on a vertical down line, instead of doing it horizontally?

That is called Coriolis accerelation. That is why the water closets flush to the right in the North hemisphere and to the left in the South hemisphere (looking the water closet from above). If going down straight you are close to the ecuator. If this do not happens as described the water closet needs to be trimmed.

I think Bryan is hiding in his wind tunnel trying to duplicate the same condition.
I don't think it was my digits. It's probably between the earth's gravitational pull and soething in the northern hemisphere. I bet the plane will do the exact opposite if I fly it in Australia ... .-)

I think he wishes it was his thumbs... :)
The push to the belly was more than the pull to the canopy... the pull was very slight.
