do you think if you went strait up in the updraft, and started spinning, youd get into a never ending spin since youd just keep bouncing up and down at the top of the updraft?
That may be possible. I think you will always have to move horizontally, because your bike swings back and forth over the wheels, especially when you brake. But here, you can bounce back and forth off the walls, and never leave the updraft. It would take constant playing; I doubt you could leave it and be playing an hour later.
