Interactive models > Percolation model

The metaphor for this model is as follows. Imagine a layer of soil with a given porosity, that is, if divided into a grid of cells, a certain proportion of cells through which a liquid will flow. Would the liquid reach the bottom of the layer?
It happens that until porosity reaches a certain threshold (between 59 and 60%), chances of percolation are quasi-nil. But after that, they rise very quickly.


Porosity: 50%
