Detailed explanation-1: -The Earth rotates on its own axis from West to East. Stars, thus appear to move from East to West, due to the relative motion of them with respect to the Earth.
Detailed explanation-2: -The rotation of the earth does cause the stars to spin in the sky, but the spinning is much slower. Whereas it takes the stars one day to trace out a circular path in the sky, it takes tenths of a second for the glow stick to spin in a circle.
Detailed explanation-3: -Stars in the sky appear to be moving because of the rotation of earth on its axis. Earth moves from west to east. Therefore, it appears as if stars are rising in the west and as day dawns they set in the west. So, stars are relatively in motion with respect to the roation of Earth.
