Physics Uncovered on Instagram: "This meal heats itself — all because of one powerful physics principle: exothermic reactions. Japan’s self-heating bentos and hot pots work by turning chemical energy into thermal energy the moment water touches the heat pack. Inside the tray is a mixture of quicklime or magnesium alloy. When water is added, the molecules bond and rearrange, releasing energy as heat — a classic exothermic reaction. That reaction generates enough thermal energy to push temperature

Physics Uncovered on Instagram: "When the professor spins with the weights held far from his body, he rotates slowly. But the moment he pulls the weights inward, his rotation suddenly speeds up — without him pushing harder or adding any extra energy. That jump in speed comes from one of physics’ most elegant principles: the conservation of angular momentum. 🌀⚙️ Here’s what’s happening: • With the weights far out, his mass is spread over a larger distance. That gives him a large rotational inert
