Question: how much do stars twinkle?

That is a hard thing to say but I can say that stars always twinkle: if they look still to you then they are really just twinkling extra fast. And if you look at stars near the horizon, they twinkle a lot more and even seem to change colour. (But they aren’t really, it is just the atmosphere wobbling the star about a lot.)
