Sorry for delay been tough last few days , but ok beans don't pop in 3 days. I take them out of paper towel and rub them down with sand paper and pop them back in with a little more distilled water and usually pop the next day , if that does not work you can get a razor blade and put the shape end in the seed to kinda of give it a little push , also I have found in case you have this problem sometimes also, that when beans pop up with the shells still on them (helmet heads - i call them ) it is because you did not plant them deep enough so they did not really have to force there way up , hence the shell stays on..... some added info fwiw... I am far from an expert thou just my thoughts and experience..... peace soser
