Abstract

Who has never played with soap bubbles? They are so beautiful and amazing, they have a perfect spherical shape and surprising tints. Foams are structures of bubbles of an incredible complexity and they are a perfect system to stimulate students' interest in the chemistry and physics of surface phenomena. In this article I propose a simple experiment that illustrates the Young–Laplace law using foams and lasers.
