Why Does the Cardboard Lift?

In this video, we will perform a very interesting Science Experiment.

Using a glass, a piece of paper, and cardboard, we will demonstrate how Air Pressure works. When the paper burns inside the glass, it consumes oxygen and the air pressure inside the glass decreases. The air pressure outside becomes greater than the pressure inside, which pushes the cardboard upward.

This experiment is very useful for school science exhibitions, students, and science lovers.

🎈 How did the balloon inflate without blowing air? 😲
This is not magic — it’s the power of Chemistry ⚗️🔥
In this classroom experiment, when acetic acid reacts with sodium hydrogen carbonate, carbon dioxide (CO₂) gas is produced.
The gas fills the balloon and inflates it automatically 🎈
📘 Students learn: ✔ Acid–Base Reaction
✔ Gas Formation
✔ Chemical Reaction in real life
👨‍🏫 Such practical experiments make science fun, easy, and memorable for students.
