Yep! I do this too and posted it in another
thread somewhere that we were talking about the filler material... Good heads up for everyone w/ exposed attys... for those who don't have exposed attys, they can take a small piece of filler and just dab it in the puddle instead... then use that filler in your next cart... you can dab the filler in the puddle and then place it in an empty cart and plug it until ready to use or go ahead and fill it as well... OR just put it in a snack size ziploc baggie until you need to use it... If you order liquids that come in a small ziploc baggie- use those to put filler w/ a small dab on it until needed to use- keeps it from drying out and keeps it from getting mixed w/ other flavors unintentionally... Hope this helps those w/ unexposed attys...
