Alright so I don't know if there is a real name for this or what you guys call them but I refer to them as "falls."It's basically a gravity bong, but it's sort of different. You get a water bottle. Cut a circle out of the cap then get a little bit of foil and form a sort of bowl in the cap and poke a few holes on the foil so you can burn the weed on top of it. Now you burn a finger print size hole in the bottom side of the water bottle. That's how you make it.Now to use it you take your cap/bowl and put your weed ontop of it. Then cover that hole on the bottom of the bottle with your finger and fill it up. Now put the cap on just enough so it's sealed. Then hold a lighter to the weed and move your finger. The water being sucked out will then suck all the smoke into the bottle. Now take your cap off and inhale what's inside.These get me so high off the littlest amount of weed ever. I don't know why but 2 bowls will have you baked 3 is almost over doing it and you save so much weed. Less that a 1 hitter.Try it out I promise you won't be let down. Let me know how it went.Sent from DEA Headquarters
