Worse case scenario put a strong latex balloon over the opening of the gallon Arizona jug and you have an improvised airlock, or splurge and buy an actual bung plus airlock.
I totally agree, should have put an airlock on it but I'm being lazy about this and wanted to test out my Macgyver fermentation skills to see how simple of a setup one could use, worst case scenario I loose $3 on this experiment.
The jug was quite swollen this morning with a little krausen at the top and is producing very bready aromas now.
