Abstract A bidisperse granular mixture in a slightly tilted compartmentalized chamber is experimentally found to show size segregation when vertically vibrated. A surface slope develops and large particles congregate to the lower side. Particles right upon the upper tip of the dividing wall behave in a competitive way, i.e., they can go to either compartment depending on the force exerted on them.
