Abstract
The Young-Laplace equation is usually introduced using mechanical rather than thermodynamic arguments when teaching surface phenomena at an elementary level. We discuss here three mechanical methods to deduce this equation, with the intention of avoiding certain misunderstandings that are found in these derivations, thus providing the correct demonstrations of the equation.
