Hmmm Foil Puffing up or out will only say that someone is blowing into the hose. could be after taking a hit when the water moves back up the stem to the level in the vase that could cause this blowing action. Also the foil must be pulled tight try what Patelboy2006 does he tapes his foil around the stem of the funnel to hold it tight.
