The video explains why, despite the abundance of water on Earth, many people struggle to find drinkable water. Most of Earth's water is salty sea water, which is not suitable for drinking. The video introduces the desalination process, which removes salt from sea water. It describes how heating salt water causes evaporation, leaving salt behind, and how the water vapor is collected and condensed into fresh, drinkable water.

What is done with the water vapor after it evaporates from salt water?

What is the final product of the desalination process that is safe for us to drink?
