Ok this thread seems pretty silly, but I have experienced this to some degree. First of all I am sure there is some reason for the silly design but I am not pleased that tiny gas particles fly all over the tank when I fill up. I think the gas shows over the metal plate due to all of the air bubbles the turbulence from the bar creates. It settles. Then another squeez of the nozzle and again air bubbles and turbulence, then settles, etc. Just a thought?
