Uranium glass

Uranium glass is a type of glass that glows in the dark, like magic! But how does it work? Well, it's made with a special ingredient called uranium, which is a type of element that scientists use to make nuclear energy. But don't worry, the uranium in glass is not very dangerous and won't hurt you if you touch it.

When the glass is made, a little bit of uranium is added to the mixture, which turns the glass into a beautiful shade of green or yellow. But that's not all! When you shine a special light called a black light on the glass in the dark, it glows bright green because of the uranium.

It's just like having a secret superpower! But why do people like uranium glass so much? Well, it was really popular a long time ago, in the 1920s and 1930s, because it was so unique and interesting. People would use it to make fancy glasses or decorations for their homes. Nowadays, people still love uranium glass because it's a cool and rare collectible item.

So, that's uranium glass, a special type of glass that includes a bit of uranium, which makes it glow in the dark and a unique decorative item that many people enjoy a lot!
