I’ve heard that when you strike flint with steel, the flint shaves off small pieces of the steel and that’s what makes a spark, but even if that is true I don’t understand how shaved steel makes sparks.
In: Physics
Steel is actually flammable. Sort of. As it reacts with air (rusts) it gets super hot. Normally this reaction is super slow, but tiny shards flying through the air will generate enough heat to glow red hot.
