Is Nitrogen heavier than air? I should know but.. I'm cloudy. If it is, a cheap way to do it might be to get one of the canisters of nitrogen that is used for purging partial bottles of wine. Another thought I've had but haven't pursued is to get a ton of marbles.. sanitize them and use them to adjust headspace... A real positive with marbles, if it makes sense, is that the gunk will settle in the spaces and make racking cleaner????

A fine beer may be judged with only one sip, but it's better to be thoroughly sure.
