Why does toast turn brown?
You slide a piece of bread into the toaster, push the lever down, and wait. A minute later, out pops toast — golden brown, crispy, and smelling amazing. But the bread didn't have any brown paint hiding inside it. So where did that color come from?
The answer lives in the bread itself. Bread is packed with two invisible ingredients: sugars (tiny sweet molecules) and proteins (long chains of building blocks called amino acids). When the bread is cool, these ingredients just sit there, minding their own business, like kids on opposite sides of a playground.
