The centrifrugal force ( the wheel spinning ) is what keeps the wheel upright...junior school stuff.....but a GREAT DEMO !!!!

Took my kids to the science centre, and they were playing with these. If you stand on a turntable while holding a spinning wheel like that, and then tilt it either way, it makes you spin around on the turntable.

#4 What doctor could you possibly be that you don't know anything about physics? Religious studies?

#3 ASAMOF what really keeps the wheel in the vertical is a less know property of any rotating object called "Moment of inertia", which is the resistance to changes to its rotation:

By the way, that's why you down fall off your bike.

"Physics, out of my league , Feels good to be a doctor. Where don't have to use too much brain as compared to the physicists!!!"
dragonon i am studying medicine, and if you are in fact a physician and have no idea what is going on in this simple demonstration??? LOL this is a basic as physics gets--where did you get your degree???????

lol. All (#6 , #7 and #12) got it wrong or this is not what i meant to say.
I was implying that practicing doctor ( not the researcher one or PhD)when acquires experience throughout his life time, doesn't have to think too much due to living in a specific region with specific diseases.
#12, i did know this gyroscope effect. My above comment wasn't about it.
That comment occurred to me coz i see a lot The Big Bang Theory... lol! SHeldon"""
@#6 Perhaps, i should have taken english lectures seriously.

#18, I don't get you, why driving unicycle would be impossible?
#9 is right, the wheels moment of inertia helps you to balance the bicycle. That's why it's easier to balance when the wheels are spinning, than when you are still. More speed, better balance.
And the same happens with an unicycle.

#19 I think it has more to do with the angle at which the front wheel fork is welded to the frame (slightly back), so that it 'wants' to turn by itself as you tilt the bike. You can stay balanced on a bike even at low speeds (in this video I think it passes 1000rpm), not to mention the mass of the wheels & tires is very small compared to the mass of the human driving it.
