Liquid oxygen
Okay, so do you remember blowing bubbles with bubble solution and a wand? Well, imagine a very special kind of liquid that is like the bubble solution, but instead of making bubbles, it can make things go super fast! This special liquid is called "liquid oxygen."
You know how we need air to breathe? Well, when we breathe in, our body takes the oxygen from the air and uses it to do things like move our muscles and keep our brain working. Liquid oxygen is like a super-powered version of the oxygen in the air that can be used to power machines and rockets.
Now, liquid oxygen is a bit different from regular oxygen because it's not a gas like the air we breathe. It's a liquid, like water or juice, but super, super cold! It's so cold that it's -297 degrees Fahrenheit! That's even colder than the coldest winter day you've ever experienced!
Because it's so cold, liquid oxygen is usually stored in special containers, kind of like water bottles, but stronger and better, called cryogenic tanks. These tanks are like really big thermoses that keep the liquid oxygen very, very cold until it's ready to be used.
When liquid oxygen is used, like in rockets, it's mixed with special fuels that make it burn really, really fast. This creates a lot of heat and energy, like when you light a firecracker! This energy can be used to make things go really fast, like rockets going into space or racing cars going really fast.
So, that's liquid oxygen, a very special liquid that's super cold and can be used to make things go really fast!
