Gas-filled tube
A gas-filled tube is like a tiny light bulb that has gas inside of it. When you turn on the electricity to the tube, it makes the gas glow and produce light.
Think of it like blowing up a balloon and then shining a light on it. The gas inside the balloon makes it glow and look cool! But instead of a balloon, the gas-filled tube is made of special materials that make it a more controlled and efficient way to produce light.
Gas-filled tubes have been used for lots of things, from lighting up signs to helping scientists study the properties of different gases. And they're still used today in certain types of lighting, like neon lights. So if you see a bright, glowing tube somewhere, there's a good chance it's a gas-filled tube doing its thing!
