Why do stars in the night's sky appear to twinkle?

Twinkling stars have wobbly light, which can be modeled by the vibration of a stretched string.  In addition, the eye also acts like a lens with a particular focal length, which produces a natural telescope effect that can make stars look bigger or smaller, depending on where you’re looking.

Isn't it because the light of stars bends as it goes through our atmosphere?
