in school i did independant study in my own time. learning the "truth" if thats what you want to call it.
i have never seen one acctually go a different way, but dont you think an american manufacturer would make a killing on selling toilets that drain the oppisite direction... i can see it now "Feel like you are in Brazil when you flush your sh*t down the toilet, even when you aren`t there"
In Australia, another company makes the majority of drain dies, and their technique is slightly different, so the drains work slightly differently.
As for gravity in space, and space being a vacuum...yes, there is no such thing as "zero gravity", or even a true vacuum. There are countless atoms floating around in space...which eventually converge to become stars and planets. Those all have gravitational forces, however sleight, on everything around it. Leave Earth`s gravity pull, and you`ll feel the sun`s pull. Leave the sun`s, and you`ll be pulled to the nearest largest star.
But all other things being equal in a drain or funnel that doesn`t get the fluid rotating in a specific direction, the coriolis effect IS enough to get it spinning in the appropriate direction.
A pencil set upright won`t fall over by itself, but give it a little nudge, and it does the rest by itself. Same with drains. The coreolis effect is just the little nudge to get it spinning.
Yes, there is a Coriolis effect, but it is FAR too small to have any effect on any bathroom sink. Hell, it doesn`t even affect HURRICANES below the 10th line of latitude. So, no it IS false.
Further more, why the hell would we need soap or anyother type of disinfectant if it takes germs 5.01whatever to stick to anything. Come on that`s plain nonsense. If that were the case doctors could do surgury with out so much as washing thier hands so long as they didn`t touch the patient for 5 seconds.
There is no gravity in spaceBlame the term "zero-gravity" for this common misconception. Gravity is everywhere, even in space. Astronauts look weightless because they are in continuous freefall towards the Earth, staying aloft because of their horizontal motion. The effect of gravity diminishes with distance, but it never truly goes away. Oh, and while we`re at it, it`s also untrue that space is a vacuum. There are all kinds of atoms out there, albeit sometimes far apart (and this thin gas adds to the collective gravity budget, too!)
and then complane when i get a zero?
Aw, but you know every little kid is going to want to test that!
"Humans use only 10 percent of their brains"...I don`t know...some people make you question this one...;-)
