Storage tube

A storage tube is like a special jar that can hold information or electricity. It has a very important job because it can remember things without electricity. Kind of like how you can remember things in your head even when you're not looking at them or talking about them anymore.

The way a storage tube works is like this: when electricity goes through it, it changes the way some tiny, special parts inside the tube are arranged. Those part stay that way even after the electricity is turned off. That means the information that was stored in the tube is still there, even if it's not being used right away.

This is really useful for things like computers or other electronic devices. They can use storage tubes to remember information even when they're turned off. That way, when you turn them back on, they can remember what they were doing before and start right where they left off. It's like a magic trick!
