Minecraft Flint vs Real Life Flint🔥

In Minecraft, flint lights fires. In real life, the teacher heated the Lighter Flint past its 150°C ignition point (until it was red-hot), then shook it into a mini sun. What is lighter flint actually made of? Not stone. It's ferrocerium , a man-made metal mix. It's brittle, so it breaks into tiny pieces easily, and it contains cerium, which catches fire at around 150 to 180°C. Hot tiny pieces meet the oxygen in the air, and each one burns as a spark that can reach about 3,000°C. That's why a flint lighter throws such insane sparks. Same chemistry / physics as this demo, just tiny. Heat it red-hot and shake it, and you get hundreds of burning fragments at once - a shower that looks like a flame ball.
