The science involved in blowing up balloons is called bubble science. A bubble is formed when the air is trapped inside the soap film. A soap film is formed from the reaction between the chemical compounds in the soap and water. That means the bubble surface is completely enclosed in soap molecules both from outside and inside. And the water molecules form a thin layer between these two soapy surfaces and making it appear like a water sandwich with soap. The air pressure, force, surface tension, water molecules, adhesion, cohesion, and atoms are involved in bubble science.
