The Earth spins in space due to an action called angular momentum. The Sun is considered the fixed point of the Earth, which is why the Earth rotates around the Sun.
Basically in empty space.

Astronauts make Earth spin
Earth's gravity keeps you drawn in toward the ground.
The Earth would spin of into space. To see a show where the Moon did that-search Space 1999.
The earth's center of gravity is the center of the earth, or the center of the mass with the mass being the earth. The earth spins as it moves through space on account of sun's gravitational forces and because there is nothing in space to get in the way or stop the earth from rotating.
First of all, you would not even need the flat surface in space, since the ball has no reason to want to fall anywhere in space. Once you give a ball a spin in space, it continues to spin forever, or until something comes along and grabs it to make it stop. (This happens to be exactly what the Earth itself is doing.)
More space?
what does earth spin on besides a inmaginary line? ============== Planet Earth rotates on its axis.
The term is called 'Rotation', or more commonly used, Earth's Rotation. :)
No, it takes 24 hours for the Earth to spin.
It is because of the earth gravity, without it, when the world spin, everything will go into space
