Why do Stars Twinkle?

twinkle twinkle lil star....

They don't, really. The stars pour out uninterrupted streams of light.

It is our earth's atmosphere that gives the strange effect.

The air is disturbed, for example, by being unequally heated, and this causes the light of the stars to be unequally refracted and so distorted. If you hold a torch on the far side of a jug of water and disturb the water, you get a "twinkling torch!"
