I love the "Ooops" threads, they are some of the most useful, IMO. My latest boner - I re-use bottles from premade liquid, and I have several types. Unfortunately, the nozzle tips are almost the same, but not quite. So when mixing up several test batches, I really should make sure to keep each tip with its proper bottle. Otherwise, I may think everything is fine when i go to try some, and the nozzle tip stays in the cap instead of on the bottle. And of course I should look closely at what I am doing every time I fill a clearo, because turning a juice bottle upside down and squeezing without looking first can get pretty messy when the tip is not on the bottle. And of course if I had only intended to add a few drops into a clearo of other juice, that is wasted too.
