The project addresses the problem of building a net connecting different places (travel, railways, short tunnels, irrigation pipes, …).
We ask to find the optimal (in space and time) and ecological solutions to do that.
Imagine
Create
Create a model of your neighborhood or the given area as it is illustrated in the images below.
Create a soap solution by dilution of some quantity of soap in a basin.
Put the model ine the soap basin and remove it. a soap film appears betwin the 2 layers of the model. This film will connect the different points on the map.
The length of the film is optimal since the soap has an elastic property and get always the minimal position. The solution is not unique.
Student can compare after that the minimal solution among the optmal solutions.
