Is Glass Really A Solid?

Glass is like a super slow-moving liquid that never really stops moving, it just moves so slowly we can’t see it.

Imagine you’re playing with syrup on a hot day. It’s thick, sticky, and takes forever to drip down the side of your glass. Now imagine that syrup is super old, hundreds or even thousands of years old. That's kind of what glass is like!

Glass starts as a liquid, just like water or syrup. But when it cools down, it doesn’t turn into a solid like ice does. Instead, it gets stuck in the middle, still flowing, but so slowly that we can't tell.

If you look at really old windows, sometimes they are thicker at the bottom than at the top. That's because the glass has been moving ever since it was made, and over time, it has settled into a shape that looks like it’s been sitting there for ages!

So even though glass feels solid under our fingers, deep down, it’s still acting like a very, very slow-moving liquid, just not fast enough for us to notice. Glass is like a super slow-moving liquid that never really stops moving, it just moves so slowly we can’t see it.
