Yes. I justified it at the moment: feasibility test. I'm building a toolbox aerator that will replace my mouth.
I've been slowly putting the aerator together that will connect to the top of the sight glass with a quick-disconnect pnuematic connector. I will use it for stirring my HLT water, and also for aerating my wort in the boil kettle while chilling.
