yeah that always sux when ya cant get em to pop!  i use the paper towel method myself..i take a section of paper towel and fold it up a couple times so it fits in a samich bag and i MOISTEN the paper towel..not Soaked..i take the sink fauct and make just a lil trickle of water come out and go back an forth on the paper towel till its moist.. not wet enuff to squeeze water out....then i open up the paper towel and put the seeds in one of the folds and close it back and put in samich bag..put in warm dark place....dont keep openin up the bag to see if they popped yet...u can hold it up to a bright light an see when the tails pop out..if ya keep opening up the bag it can dry out and germs can get inside and the water will make the paper towel turn kinda yellow around the seeds..thats not good...others will chime in with diff methods..GL
