Sugar's Vanishing Trick
What is a solution and what does it mean to dissolve something?

Stir a spoonful of sugar into a glass of water, and watch it vanish. It didn't disappear — it dissolved. The sugar is still there, hiding in plain sight. This is the magic trick chemistry pulls a thousand times a day, and once you know how it's done, you'll see it everywhere.
When something disappears into a liquid like that, we get a solution. A solution is just an extremely thorough mixture — two things blended so completely that you can't see where one ends and the other begins. Sugar water, ocean water, even the air you're breathing — all solutions.
