What makes a star "twinkle"?

Last night I went far out into the Alabama country to get a truly awesome view of the nighttime sky. I saw several shooting stars, but what interested me more was the fact that at least two objects I saw, which were not Jupiter nor Mars, were visibly "twinkling" -- from red to blue to white to red and so on.
What were these objects? Planets? Stars? What made them appear to be twinkling?
