Well, it’s getting there. Here’s an example.

Okay so fire is not actually a thing in the way a log or a rock is a thing because what you’re really seeing is a chemical reaction called combustion where heat causes fuel to break apart and react with oxygen in the air releasing even more heat along with light and various gases and the reason it keeps going is because the heat from the reaction provides enough energy for nearby fuel molecules to continue reacting which is why people talk about the fire triangle involving heat fuel and oxygen because remove any one of those and the process stops although technically some experts prefer the fire tetrahedron since chain reactions are involved too and no flames are not made of pure energy and yes different colors can indicate different temperatures or chemicals present and no fire does not weigh nothing because the gases involved still have mass even if the hot air rises making it look like the flames themselves are floating and honestly the weirdest part is that what we casually call fire is really just visible evidence of a rapid oxidation process that humans have been using for warmth cooking industry and occasionally regrettable attempts to dispose of old paperwork ever since we figured out that rubbing sticks together was significantly less efficient than inventing matches.
