What if you could turn the same material into a conductor, insulator, magnet, or even a superconductor just by twisting it? Meet magic angle graphene, where a tiny 1.1° twist creates a whole new world of physics. The material is carbon, the same stuff found in a pencil, but its properties can become extraordinary.

Video Summary
AI GeneratedScientists have discovered that twisting two layers of graphene to a \"magic angle\" of 1.1 degrees creates a moiré pattern that fundamentally alters its electrical properties. This allows the material to switch between being a conductor, insulator, or superconductor via voltage, offering a new way to manipulate quantum states without changing chemical composition.
