Liquid Mirrors

A liquid mirror is a reflective surface that consists of a thin layer of liquid metal, typically mercury or gallium, spread out evenly on a flat surface. When still, the liquid reflects light like a traditional mirror, but can also be easily manipulated to change shape or angle. Liquid mirrors are often used in astronomical telescopes due to their large size and lightweight construction, allowing for a clear and precise view of the night sky. They are also used in artistic installations and decorative pieces due to their unique and mesmerizing properties.
