hey i just bought a nice used bong from some kid i know for 40$. it has a precooler, slitted downstem, and a dome perc with four little slits around it for the smoke to come through. Today i was trying to smoke but the bong wasn't bubbling, like i couldnt pull any smoke/air through. so i removed the precooler as if i was going to clear the bong (but there was no smoke in it this was all a test) and nothing could come through. i narrowed the problem down to the dome perc. I think the tube in the center of the dome that brings smoke from the main chamber of the bong is clogged or somehow stuck. how could i unclog it or fix my bong another way?! thanks in advance
