Sushi anyone?

i thought fire existed just because there is a high heat and a fuel nearby and this fuel will flame up when it heats up to a specific temperature(depending on the fuel) thus causing combustion of the fuel.

but hey who am I?

You're missing oxygen.. it's called a fire triangle

It's not a fire triangle anymore. It's a fire square because of the added "chemical reaction" dynamic.
