Facts
One of the people who discovered didn’t know what it was but when he breathed it in he said it wasn’t different from normal air but it made him feel good. They eventually found out it grew fire and they fittingly named it fire air, but they weren’t the first ones to try to figure out what it is some people in Egypt tried to understand it but they didn’t have the technology to be able to find it.
Where its used
