Stars twinkle because the air in our atmosphere is moving around. Imagine you're looking at a light through a wobbly glass of water, it flickers, right? The same thing happens with stars: the Earth's atmosphere moves and changes temperature, making the starlight bend and flicker as it comes down to us. It’s like the sky has its own version of a wobbly glass!
Examples
- You see a star twinkling as you walk across the street on a cold evening.
