Here in The Canal Zone, we have a pretty cool way of getting massive bong rips. Hardly a day goes by without a bale of weed washing up into one of the locks. I'm not saying that it's the best though we can get some pretty exotic shit from time to time.
Anyway, there's this place, way up high on the Gatun Locks - on the actually swinging part - where you can stuff a whole bale of weed. Then you hang over the edge with a blowtorch while they pump the water out of the lock. Ya see, the water in those great big loch gates drops to causing them to 'inhale' the entire bale. Then, when the water floods back in, a three foot column of smoke shoots out the side for a full twelve minutes! All us longshoremen gather round and get a massive power hit from one of the greatest civil engineering accomplishments ever.
