So I had an airlock sitting in a glass of one step solution next to my sink last light as I was finishing brewing. Sometime after I took out the airlock for use my lovely girlfriend, who had been satisfying her homebrew craving for most of the evening, decided she needed a glass of water and saw a convenient one already filled next to the sink.....What Luck! She downed the whole glass before noticing flavor wrong-ness. I got more than one good laugh out of the incident.
