Okay, so you know how we need air to breathe, right? Well, sometimes people who do special things like scuba diving or space exploration need to breathe a different kind of air that's called hydrox.
Hydrox is made up of two gases, just like air is made up of oxygen and other gases. The two gases in hydrox are hydrogen and oxygen. They're put together in a special way to make a gas that's safe for people to breathe.
When people breathe hydrox instead of regular air, they can do things like go deep into the ocean or explore outer space. Hydrox is a special kind of gas that helps them stay safe and breathe easily even in places where there isn't regular air.
So basically, hydrox is a special kind of breathing gas made up of hydrogen and oxygen that helps people stay safe and breathe when they're doing special things like scuba diving or space exploration.
