It's a very mysterious thing and has been of particular importance to humanity since the beginning of its development. But what is fire? How does fire form? Why doesn't fire burn without oxygen? Or does it actually burn? How does the color of a flame depend on the element being burned? By the way, from a scientific perspective, fire is a very basic thing. And, in fact, there's even a chemical formula for fire. And fire can have all sorts of funny things. For example, did you know that fire has a violet flame? Cool, huh? What do you think violet fire is made of? Okay, spoiler alert: the color of a potassium flame is different from the color of an aluminum flame. And of course, we'll touch on the history of lighting a little. Of course, we could. The first gas lamps and so on. In short, fire is unusual, perhaps just as unusual as water. It's just less talked about. And most importantly, in today's video, we'll understand why we are fire! For advertising inquiries ➡ [email protected] Instagram ➡ @blogreg
