text:  Now, I'm not a mechanic, and I certainly had no role in inventing the combustion engine fueled by petrochemicals. However, I can explain pretty easily how it works because it's not complicated. There's a blend of air and fuel and a spark plug, and basically mini explosion goes off, which pushes a piston down, which rotates an axle that spins your wheels. It's not hard. I mean, you can watch an animation on social media right now.
