Chemical Reactions.
๐ฏ Your mission
Play with the model. Break it. Understand it.
โก The twist
If it bubbles, something invisible is escaping.
Mind = Blown
๐ง Hot water can freeze faster than cold water under the right conditions. Nobody fully understands why.
Make a hypothesis first

What You'll Learn
Distillation separates mixtures based on different boiling points. Heating salt water causes water to evaporate and condense, leaving salt behind and producing fresh water.
Key Words
- solubility
- concentration
- plasma
Steps
