Coding a 2D physics engine from scratch — and using it to simulate a pendulum clock

@thephysicslabs on Instagram: "DIY things are proof that creativity and physics can turn simple materials into something amazing. 🛠️ With everyday items like bottles, cardboard, rubber bands, or paper, you can create tools, experiments, and solutions that actually work. DIY projects teach how force, balance, pressure, and energy behave in real life. When you build something yourself, you understand why it works, not just that it works. A rubber band stores energy, folded paper gains strength, a
