Chemical Reactions.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
Color changes mean atoms are rearranging — even if you can't see them.
Mind = Blown
🧪 If you could remove all the empty space from atoms, the entire human race would fit in a sugar cube.
Make a hypothesis first
Before you mix: what color do you think it'll turn?
What You'll Learn
Matter is made of tiny particles that are always in motion. In solids, particles vibrate in place; in liquids, they slide past each other; in gases, they move freely.
