Teaching You things that nobody does on Instagram: "People sometimes talk about a “melting” or heating pen made from everyday items, but what’s really being shown is the idea of electrical resistance turning energy into heat. When electricity flows through a material that resists it, that energy has to go somewhere — and it usually shows up as heat. In concepts like this, the pencil or metal isn’t special by itself. It’s just acting as a conductor with resistance, where electrical energy convert
