Made_to_Explain on Instagram: "The video showcases a mechanical "infinite" domino loop. While gravity's natural role is to pull objects toward the Earth, these clever LEGO-like mechanisms use a transfer of energy to overcome the "one-way" nature of dominos. Each domino is mounted on a pivot. When one falls, it hits a lever or a gear system that uses the force of the fall to "reset" a domino further down the line. By arranging these pivots in a circle and adding a small motorized element (or a pr

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
