Man, bongs are great. Just fill it up with some water, but not enough to flood the stem. Then pack the bowl on the end of the stem with your finest ganj. Rip that shit up, keep your finger on the carb hole though. Once your about 3/4 full of smoke let go of the carb and all the extra smoke goes whoosh! into your lungs. Hold in for 3-10 seconds. Oh, try putting a little listerine and ice in with your bong water, it will blow your mind.
