What Makes a ‘Laser’ Beam So Special?

Imagine you're in a dark room, and all the lights are flickering. A laser is like a super-focused flashlight that doesn’t flicker at all, it shines one straight line of light with perfect brightness. That’s what makes it so special! It works by getting many tiny particles called photons to move together in the same direction, like soldiers marching in step. When they all line up and shine out, they can do amazing things, like helping doctors see inside your body or making your phone screen glow.
