Stars twinkle because … they're so far away from Earth that, even through large telescopes, they appear only as pinpoints. And it's easy for Earth's atmosphere to disturb the pinpoint light of a star.

Hey there !
Stars twinkle due to atmospheric refraction of starlight. As the star are very far away, they behave as point source of light. The path of rays of light coming from the star goes on varying slightly, the apparent position of the star fluctuates and the amount of starlight entering the eye flickers so sometimes, the star appears brighter and at some other time, fainter, thus the star twinkle.
Hope it helps you !
