Fun With Plateau's Laws.

1. Soap films are made of entire smooth surfaces.

2. The average curvature of a portion of a soap film is everywhere constant on any point on the same piece of soap film.

3. Soap films always meet in threes along an edge called a Plateau Border, and they do so at an angle of cos?1(?1/2) = 120 degrees.

4.These Plateau borders meet in fours at a vertex, and they do so at an angle of cos?1(?1/3) ? 109.47 degrees (the tetrahedral angle).


A morning of soap bubble fun with Evie.
