Unblowing bubbles: Understanding the physics of bubble deflation through a straw

Year: 2025

Type: article

Abstract: A formal description of the deflation process of a soap bubble attached to a cylindrical tube is provided, with emphasis on quantifying viscous and unsteady effects. Differing from prior studies, the proposed theoretical framework maintains its validity across a wide spectrum of parameter values that define the system. The model is validated through experimental results that can be reproduced at home using liquid soap and a straw, emphasizing its educational aspects.
