I have asked around, and realized I need people with an understanding of how a keg works. I have to fill a commercial manual pump keg with instant iced tea and a bit of yellow food dye to make fake beer for a theatre show. Got the expertise to open the keg. Have a manual pump. I just need the liquid to come out. I do not need carbonation, and believe me, they won't spring for a CO2 maker anyway.Will pumping the keg be enough to make the tea come out??? People keep saying CO2 does that, but I don't think so. The air from the pumping should do it, right? please help me, brew people!!!!
