percolation
Liquid through grounds
Percolation is the process of liquid filtering slowly through a porous material.
Coffee percolates when hot water passes through grounds.
Water percolates through soil to reach aquifers.
The word extends to gradual spreading or seeping: News of the scandal percolated through the organization.
In physics and mathematics, percolation theory studies how connected pathways form in random systems.
