Anodizing is like putting a colorful coat on metal. You know how you like to color in your coloring book with crayons? Well, metal can be colored too! Except instead of crayons, they use special chemicals to add color. But it's not just for looks, the colored layer also helps protect the metal from getting scratched or ruined. Think of it like putting a strong shield on your toy so it stays shiny and new. And just like how you can choose different colors of crayons, metal can be anodized to have different colors too!
