:thinking: maybe we should outline all possible ways?
the ones i know:
mouthfull of water like stealing gasoline.
pump on inside end, then take it off when it gets over enough.
sink utube and saranwrap both ends. try and repeat.
burn up a pump on the dry end for awhile
get a big enough sump to get your head in there. take a big swig of saltwater and blow it up to the top and over until there isn't any air in the line.
