Air has mass because it is composed of particles (molecules and atoms) that have mass.
The YouTube video "How to show the air has mass" demonstrates this principle through a simple experiment:
- A balanced stick with two balloons attached.
- One balloon is inflated, and the other is not.
- The inflated balloon tips the balance downward, showing that the air inside the balloon adds weight/mass.
This experiment visibly proves that air has mass and therefore weight, as stated in the video: "We will see that the blown up balloon tips the balance downward thus proving that air has weight Mass Try."
