What effect will this have on our weather, greenhouse effect etc? It's a huge leap, but I noticed that creamer in my coffee always used to spin in an anti-clockwise direction. Now it frequently spins clockwise. (I am closing in on 70 years old and have observed this, and many other inconsistencies over the years). Thank you for your time.

Yes, it's moving and every now and then (like, millions of years) it reverses direction. The North Pole goes South and viceversa.\nBut I'm sure that has nothing to do with your coffee creamer!!!

Yeah, Im pretty sure wrapping your hands around it wont affect it at all. And only a paper cup would be affected at all obviously.\n\nYour hands are generally room temperature, and even if they warmed up from holding the coffee, they would only be effecting a small amount of surface area of the coffee -ie the coffee on the side of the cup.

It depends on the toilet, not the hemisphere.\n\nYou are thinking of something called "the coriolis effect".  This is the effect which causes water to try to spin clockwise in the southern hemisphere and clounter-close wise in the northern hemisphere.  Although this effect is real, it has a negligible effect in everyday life, like in the draining of toilets.  Compared to other factors, the coriolis effect is extrememly weak and for all intensive purposes, does not influence the effect of water draining out of a toilet.

It doesn't. Go south of the equator and you will see it spins clockwise.

The magnetic field switches every 2000 yrs or so. Its due to switch soon. When it does, your compass will point to south instead of north.

What you're describing (the water staying in a glass even if you spin it quickly over your head) is not the result of gravity. That is a the result of net motion forces.  Gravity is caused by a massive object creating a 'fravity well' in space-time.  Motion is not required for gravity to have effect and the effects of gravity at (theoretically) infinite in scale, though the true magnitude of force is negligible from far away.  Every mass excerts gravitational attraction on every other mass.  I suggest you read the Wikipedia article on gravity, and then pose this question again.

yes, you are right- the ideas of up and down are indeed relative. On earth, we have a wonderous and magical force called gravity- which solves the problem easily as we are best one way up really. so technically, neither you nor the paper is upside down. It does however make sense to assume in such a situation that the paper is at fault and turn it round, rather than yourself. Or does that pose another question?

As the earth rotates on its axis, the atmosphere is rotating with it.  Otherwise there'd be a constant wind, like in a fast-moving car on a still day,  as we were dragged through the atmosphere at the speed of the earth's rotation, yes?   And all winds would blow from east to west, and we know that's not the case.  \n\nBut the rotation of the earth does have an important effect on the weather.   A strange thing about rotating a globe is that a point on the equator has to move much faster to make it all the way around the waist of the globe in 24 hours than a point up around the Arctic circle has to move to make it all the way around the Arctic circle in 24 hours. (you can test this with a piece of string: The length of a piece of string wrapped around a globe at the level of New York is much shorter than a piece of string wrapped around the globe at the equator, right?)\n\n  You know that, looking at the globe with the sun behind your back, as the world turns, the continents pass off to the right (the east). New York crosses into the sun at dawn while San Francisco is still on the dark side of the globe.  Because the surface of the earth at the  equator is rotating faster than the surface of the earth 500 miles north of the equator, so is the air above it.  But the air above the equator isn't attached to the air above a point 500 miles north.  So the faster-moving and slower-moving air rub past each other.  This forms a kind of bow wave at the equator, like the wave that peels back from the bow of a boat as it moves through the water. Think of a big arrow pointing to the right and wrapped around  the equator.  So the air peels  back to either side of the equator, and forms a swirling current--curling counter-clockwise above the equator and clockwise below it.  This is called the coriolis wind.  It's one important factor in where weather comes from.

Liquid would hit the ground first due to the movement of the liquid inside the can. It produces more speed because the shift of gravity and would "beat" the other can to the base of the incline.\n\n---------------------------------------------\n\nIf anyone has other questions that they want sent specifically to me, please send them to yourqandaperson@yahoo.com -- Please keep them appropriate and ask only realistic questions or your question will be deleted and reported!

OMFG. I love ScienceFair, and I hate it all in the same.\n\nUse my topic: Magnets.\nHypothesis: Does temperature affect the strenth of magnets?\nProcedure(truncated):\nTake however many magnets you need for your trials(mine was 45) and separate them into even groups of 3. Example, 3 groupd of 15 from 45. Test a regular set, one magnet at a time, with 50 paper clips, and see how many it picks up out of 50.\n\nNext, take your second set, and put them in the freezer for 24 hours. When they're done, test that set and record how many paperclips they pick up out of 50.\n\nFinally, take your 3rd set and boil them. Test them, holding the magnet with tongs, and record your data. \n\nNOTE**** Important: You can't use only one set of magnets, the boiling and freezing off sets the balance inside the magnet!!!

hey talking to me should cheer you up! lol jk... but guess what? margarine is only 1 molecule away from being plastic. seriously. not like that's particularly funny, but it's interesting!! if you leave margarine out for flies or bugs, none will come to it. it will just sit there, like plastic. eating margarine is like melting down a kid's sippy cup and spreading it on your toast. lol just thought you'd like to know...

Not quite! The direction the water goes down the plug-hole depends on whther you are in the northern or southern hemisphere. It has nothing to do with magnetic fields, but everything to do with the coreolis effect, which is caused by the direction in which the Earth is spinning.

Americans are in hurry.  We make instant coffee in a microwave.  Now what does that say about us?\n\nI did meet an old man once who seemed to be relaxed.  He was seated on a bench where I was buying gasoline.  I asked him if he had lived in the little town all his life.  His reply "not yet".\n\nDid you notice I spelled out "gasoline", there will be no shortcuts for you.

Ask your son to turn around in a circle once per day.  That is the rate  of the earth spinning.   One rotation per day.  Did he get dizzy?  \n\nSpinning is angular speed or angular frequency( the rate it turns through an angle), not the speed, tangent to the circumference of the earth.\n\nThe earth spinning is improperly linked to 1000 mph.  The earth spins one time per day.  The surface velocity is 1000mph at the outer surface of the earth, but that is just like going straight at 1000mph.\n\nThe surface speed of the earth is undetectably with out a frame of reference.  Just as speeding in a car...without looking out the window, you don't know if you are moving that fast.  We only detect a change, acceleration.  The earth spins so slowly, we don't detect the angular frequency as being dizzy.

HAHAHAHA You all forgot about our little friend called drag! Inside or out the ball has a drag force acting on it by the surrounding air. Like stated before the air in the car is moving with you, and the car, and the ball all the same and the drag force on the ball at this point is negligible. This is not the effect of a vacume, a vacume is the absence of air. is it possible for there to be no air in the car? NO, Sooo.. outside on a bike or where ever, you are traveling at a speed where the balls light weight will be significantly affected by this drag force and it will cause it to slow down as you throw it up and while you keep riding on un affected by the static(motionless) air, your ball only has one force acting on it, air drag causing it to slow behind you.   test this by throwing a variety of same shaped objects while riding and you will see that the one with the most density will keep up the best. try a marble V.S. a ping pong ball.  then do it in the car

if a plant is in a windy area, evaporation happens faster. Or in not too bright of sun, photosynthesis happens faster.  Also, if it's well watered, the roots suck more in and push it through the plant.  \n\nThis probably won't help at all, since I have no idea of what you're really talking about, but someone once told me that they liked nothing more than attempted BS.
