Connect Quantum Superposition to a Coin Flip

You've heard quantum superposition is weird but not why. This explains it in plain language, then maps it onto a spinning coin, and crucially shows where that analogy holds and where it falls apart. The point is to see what makes superposition genuinely strange and not just ordinary probability in a lab coat. Pitched for a curious non-scientist.

Help me understand quantum superposition by connecting it to something I already know. First, explain what quantum superposition means in plain language. Then compare it to a coin spinning in the air: where does the analogy hold, and crucially, where does it break down? I want to understand what makes superposition genuinely strange and different from everyday probability. I'm a curious non-scientist who has heard the term but never had it explained clearly. Finish with why this concept matters for quantum computing.
