How Does a Laser Cut Through Metal Like It's Nothing?

Imagine shining a flashlight on a piece of paper, it gets warm. Now, imagine that flashlight is super powerful and focused like a tiny sun. That’s how a laser works! It shines such a strong beam of light onto metal until the metal gets hot enough to melt or cut right through it. The more powerful the laser, the faster it can cut.
