What Is A Waterfall Marijuana Bong?


aqua lung marijuana bongHow to Make a Homemade Waterfall Bong

A waterfall bong is extremely easy to make, requiring only a bowl or bong stem and a plastic bottle to make. Don’t get the waterfall bong confused with it’s cousin, the gravity bong, which is not the same thing. A gravity bong is kind of the same science, just in reverse, and with a different design. You will see what I mean.

What You Need:
1. Metal pipe bowl or bong stem
2. Plastic bottle
3. Lighter
4. Your preferred marijuana strain
5. Drill or knife

I have heard of the waterfall also referred to as an aqua lung, a third lung, or in my circle of friends, simply ‘the liter.’ Whenever my friends or family want to ‘take a liter’ we always flash each other the ASL sign for the letter ‘L’. Very discrete, and has served us well in ninja situations!

Waterfalls get you extremely high from very little marijuana because of the amount of smoke inhaled all at once. How does this happen? Waterfalls are so effective with very little marijuana due to the shear amount of concentrated smoke filled with THC being forced into the lungs all at once. Also, because the bottle is air-tight the only air entering the bottle is smoke filled with THC.

To make a waterfall bong, start by making a a hole in the bottom or side of any plastic bottle. The 2-liter plastic bottle is the best, but a smaller plastic bottle will do, you will just get smaller hits. If you can find the elusive 3-liter bottle, especially the one with the wider mouth, you can make a ‘super waterfall’. *Note – a wide mouth cap is not compatible with other bottle sizes.* Make the hole about the size of a nickel, and as round as possible. This hole will be used to let the water out of the bottle and fill up the bottle with smoke from the marijuana being burned at the top.

I have made hundreds, if not over 1,000 waterfalls in my lifetime, and people always marvel at how well they function. There isn’t really a secret – the bottom hole is as perfectly round as possible and as directly in the middle of the bottom of the bottle as possible. This creates a streamlined flow as the water level drops, which doesn’t occur if the hole is on the side of the bottle or the hole is all jacked up.

Some people will just jab the side of the bottle with a knife, or poke the bottom with a burning hot screwdriver or some other ‘Macgyver abomination’ tactic. If you can use a drill, you will punch a hole very easily. I have mastered carving out the bottom hole with a knife, which is good too, but takes time. It’s worth it though. Make sure to keep the cap on the bottle to make handling the bottle easier when you are punching the hole. If the cap isn’t on the bottle, the bottle will collapse when you are trying to punch the hole, which can be a hazard situation as the knife or drill in your hand is going who knows which direction (likely towards your other hand!).

the full bowlNow is the hardest part of the waterfall creation process – punching a hole in the bottle cap. I have been far from home many times, making a waterfall, with only one chance to punch a hole that was big enough to push the bottom of the metal pipe bowl through, yet small enough to remain air tight. I have tried to seal the bottle cap and bowl after the fact with just about every product out there, but when the bowl inevitably gets hot, the seal breaks again. If you can make the cap the correct way the right time, it is very beneficial.

My secret is making two very small cross slits using a knife. The slits need to be the diameter of the bottom of the bowl you are trying to punch through, that way it’s enough to push the bowl through it, but not enough to create air problems. You will recycle the bottles after a lot of use (in my case, almost weekly!), but the cap will stay with you forever. I refer to my cap bowl as ‘my precious’ which Ninjasmoker will attest to. It’s great for travel too, because you can get mega high when you get to your hotel, all you need is a new bottle with a hole in the bottom! The bowl cap is easy to hide.

Now that the waterfall is made, how the heck do we use this thing right? I can confidently say that I have taken more waterfalls than anyone else on the planet. Ninjasmoker will attest to that, and if anyone wants to challenge me to a title match, I’d gladly put my skills on display for those that are loading the finest :) The first thing you will do is obviously load the bowl. Don’t pack it too tight. I always tell people it’s better to take two medium waterfalls than one waterfall that’s clearly too big. Leaving smoke in the bottle is poor form. You will learn that some marijuana burns better in the waterfall format than others. Super dry burns too fast. Moist and/or dense nugs barely burn at all. I get a Jack the Ripper strain and Trainwreck strain here in Oregon that are PERFECT for the waterfall.

waterfall bongThe next thing you will do is hold the bottle in one hand, with a finger plugging the bottom hole. With the other hand, turn on the water to fill up the bottle. If you are trying to conserve water, or if you are camping or something, you can dunk the waterfall bottle into the water as well. Whatever gets that sucker full. Be careful if you are doing the dunk method though, as you will go to light the lighter and get it wet, and be in a very frustrating position.

Screw the loaded bowl cap to the liter bottle full of water. With your off hand, light the bowl, while at the same time removing your finger that was plugging the bottom hole. If you do it right (not exactly hard!) you will see the bottle filling up with the milkiest smoke you have ever seen. This is why I prefer the waterfall to the gravity bong. With a gravity bong, it takes wrist control and skill to get a milky hit, and then you have to take a hit that runs the high risk of getting dirty water in your mouth. A waterfall is clean water every time, unless you are using the dunk method. Also, anyone who can hold the bottle can get a milky hit every time (sometimes too milky!). You still get water in your mouth from time to time, but it’s not nearly as bad as with the gravity bong.

All that is left is to unscrew the cap, grip it, and rip it! Waterfalls really conserve the herb, which is a good thing in this economy right? How much did your last ‘quad’ cost? Egads. Below are some waterfall tips and tricks that I have learned over the years. If readers have anything to add, please do so in the comments below so that others can benefit from your expertise:

1. Become familiar with water levels – You want to get a big hit, but not too big of a hit to where the water is gone or almost gone, and the smoke is all stale. If you like stale smoke, then by all means go for it, but I don’t. If you are taking a small waterfall hit, let the water go a bit so you have less water in the bottle to decrease the chances of water getting in your mouth.

2. No warm water – I repeat, no warm water. As cold as possible. Warm waterfalls are the worst.

3. If possible, no shake – Shake is fine in a joint, not bad in a pipe, kind of harsh in a bong, and REALLY harsh in a waterfall. ‘Piecing’ together small nugs to make a liter can be problematic as well, unless it’s really high grade.

4. Melting bowl cap – If your bowl gets too hot, toss that sucker in the freezer. Smoking melted plastic is no bueno.

5. Be careful with newbies – A waterfall invades your lungs with smoke so ferociously sometimes, that it can put the hurt on rookies. Proceed with caution. On the flip side, if someone is talking a big game about how they are ‘big smoke dogg’ then give them a waterfall and see what they do. I’ve seen many rookies get exposed when I’m on my third waterfall of the session and they are still recovering from their first one :)

  1. grow up, get a life, and say no to drugs, all need to be delivered for drugs its wrong its a sin, and ask God to help you once you start with using drugs it will lead to other bad habits .get help and stop, it can ruin your life, and by GOD GRACE AND MERCY we are a still alive. some of us can be so mess up from drugs from the wrong decision that we made when we was younger, but GOD is always they to help us if we take the time and ask him for help, may GOD bless you all

  2. waterfalls are good i probs smoke 20 – 30 of them a day with my 14mm spark plug remover brimmed from bottom to top each time, their is no right and wrong way to smoke weed its however the smoker feels comfy smoking wether it be a bong/joint/vaporizer ,etc and weeding out a proper smoker can be different from one day to the next so does not exist, a big smoker can be wiped out off one of these and in the same return can smoke a hundred of them, it all depends on your body on the day, i only smoke blueberry or blue cheese or purple haze, because thats the average green in the uk and widely available even though it is still illegal over here. and by the way johnny, i would smoke you under the table with these i wake up on a morning and have 4 on the bounce just to wake me up lol, well, enjoy your weed everyone :)

  3. rivstasellassie420 on

    I thaught it was gonna be cool but ive done it with a glass bottle. way cooler. its not the healthiest ill stick to my spliff.

  4. I have been doing this since 2000. We call them “floods”. They were created in Johnstown Pa…….hense the flood. I am sure I have done more than you.

  5. This is called a rocket bong in Queensland where I’m from! There also the bush bong where you fold a 600ml in half heat till all but the sides are fused and fill just the fold with water then put your bowl where the water would come out in a rocket/waterfall. No stem required! Then there’s the lungy which is half a 2 litre bottle with a plastic bag taped to the bottom and you pull out the bag while you lite your bud, same cap as a rocket/bucket bong.

  6. Or just get the bottle your lighter and joint/blunt and burn a hole fitted to the mouth of your preffered roll and slide it in snug but not choking it tight, burn a thumb nail sized carb for clearing smoke on either side at the bottom and chief chief chief. Same concept, just different. The only way I smoke roaches. You can make the smoke you get off your roaches go wayyy farther. #trythatshit

  7. When i was at home or just with my buddy, he and i would smoke waterfalls to conserve bud. Pack a oney each time. ohh and GATORAID/POWERAID BOTTLES! they caps are super wide so you can fit a bigger bowl in, and you can get all the smoke out at once with it width as well. after using a gatoraid one id never use anything else. it feels counter productive

  8. Its way easier to just use your lighter and burn a hole in the bottle than carving it out. Give it a try.

  9. My first New Mexico winter is also turning out to be a little colder than I expected, my hands are all cold and stiff, so it would appear we both have the same handicap. And here we go…

    I do not deny that THC can be an intoxicant, as can too much caffeine and sugar. I do not know as much about heroin, the drug or all its uses, so it’s hard for me to comment about heroin addicts. But there will always be a part of our population who will become addicted to… something. Whether it be sex, drugs, or rock and roll. (I think the cold has taken away my ability to be witty.)

    When we talk about drugs, in general, someone will always mention the addicts. We must keep people from becoming drug addicts, no matter what their age. It’s very important. However, as I have gained knowledge of how addiction works in the brain, I don’t agree with this argument anymore. Out of the ten to twenty percent of the population who’s brains are likely to become addicted (to… something), you cannot use shame and criminalization to save this population from whatever their fate may be. Just like we cannot stop people from having sex so that people will not become sex addicts, we cannot stop people from taking drugs. Sex and drugs both stimulate the pleasure centers of the brain, which seems to be the only reason why they are treated as they are in our society. So, tell me, what is so bad about pleasure? (rhetorical question)

    I understand how you feel about what people can construe as negative images of marijuana. This poor plant has faced an awful lot of prejudice. But just as there are a gazillion youtube videos of people (young and old) getting drunk and making fools of themselves, there are also a number of cannabis lovers doing the same. I just don’t see how it hurts our cause at this point, as these images have ALWAYS been around, for decades. It’s not like it is something new or different.

    Don’t think I don’t understand where you’re coming from, I do. I think my views on drugs have more to do with the science of it, rather than the legal part of it. And because of my experiences with a host of “legal” drugs, I can say that until we legalize marijuana, we really won’t be able to predict what the outcome will be. I am not one of those people who say there will be no negative outcomes at all, I just strongly feel that the positive will ALWAYS outweigh whatever the negative outcomes turn out to be.

    And where you and many others use marijuana recreationally, I have never been able to do that, I have always used it as a medicine. So as far as being stoned or intoxicated, I can only use my experiences with prescription drugs and alcohol as part of my personal definition. (Along with caffeine, sugar, and cigarettes.) But I also buttress my personal experiences with the brain science that I understand, which means that since alcohol, opioids, and marijuana all effect different parts of the brain, I’m just not as concerned about the intoxication effect of marijuana as you are, I guess.

    Now, whatdya think? Have I made my case, good sir? Because, I could talk about this all day, as the length of my posts obviously suggest. There are lots of things that are going to bring harm to the legalization battle, but all in all, this ain’t one of them. Keeping in mind this is all just my opinion. My humble, cold-but-loving-it opinion. :D

  10. I’m not sad nor angry and I’ll spend my time however I please as I hope you do as well… well as long as what you please doesn’t cause harm to innocent people then by all means have fun good sir. as far as the sad comment It is quite the opposite I was amused still am… even if I am a little put off I still remain amused and you are helping… so thanks….

  11. if there is a responsible way to consume marijuana it is by an adult of legal age as determined by the law of the land, and or under the watchful eye of a physicist. do I think marijuana is dangerous to young kids? no I think immature irresponsible people are dangerous to the cause of legalizing recreational and or medical marijuana. in fact I think that its more dangerous to the medical campaign than anything.

  12. I apologize if this doesn’t make sense i just came in from the cold and my southern blood just will not acclimate these northwestern temps.

  13. I apologize if this doesn’t make sense i just came in from the cold and my southern blood just will not acclimate these northwestern temps.

  14. an intoxicant is a substance that causes euphoric feeling and slight impairment. I wholeheartedly disagree with you that there is no separation between medicating and recreational use and or abuse. thats like saying a heroin addict is only self medicating for whatever pain issues they can’t bare. however true that may be in most incidents heroin addicts are suffering the pain of withdrawal. that being said I am not likening heroin with marijuana. however your refusal to separate the classification adds a crutch all the way across the board. I am pro marijuana legalization all across the board and if some kids parents think that their childs medical needs are met by marijuana and the state allows this to be it is none of my business and I don’t care, what I do care about is stupid immature kids doing stupid things that reflect back on us in the eyes of our opponents. one of those things is this idea of weeding out “amateur” smokers with a huge bonghit. I can out smoke most folks however my lungs have always been sensitive and big bong rips hurt me they always have and always will,. however you seem to think I’m upset I’m not I want to make that very clear. my quips comparing these kids to half wit frat boys was just that a quip… I referred to folks as chuckleheads as a joke as well. however the truth is I was one of those chuckleheads I lived in excess still kind of do… however likening them to a halfwit frat boy was more geared to popularized depiction of a frat party . I enjoy being stoned and enjoy smoking with my friends and on special occasions I will bring out extra and just get ridiculously high. not to mention your refusal to define THC as intoxicant doesn’t change the fact that it very much is and no amount of wishing it weren’t true will not change that. I also want to put this out that I don’t disagree with marijuana medically I reap those benefits as well but it has never been and never will be the reason I smoke marijuana.

  15. What is the “responsible” way to consume marijuana?

    For big pharma, it is only through prescription pharmaceuticals.
    For some in the MMJ movement, it is vaporization over smoking.
    For recreational users, it’s anything goes.

    In my humble opinion, The Weed Blog is a place where all these groups are welcome, and where anyone wanting to learn about cannabis can hang out. You can learn about how a poor college student might fashion a smoking tool, or how GW Pharmaceuticals created Sativex. While some may have a problem with the image of a Sprite-bottle smoking tool, others may think that big pharma’s unfair advantage in the marketplace is the more disgusting image.

    In your post, you differentiate between young and adult users, and while you were talking about recreational use, you can’t easily separate medical from recreational use. (In my opinion, you can’t separate them out at all.) A person’s age should not determine whether they can consume cannabis or not — it’s a person’s body chemistry that should determine whether any drug is introduced. And while it would be great if every person could afford the doctor visits and tests needed to determine what treatments would be best for any given medical condition, that is not reality. What IS reality is that cannabis can treat such a host of different ills, that it is hard to choose wrong when choosing cannabis.

    For a suicidal 14-year-old, marijuana might just be a life-saver. For a 15-year-old rape victim, marijuana could treat PTSD. It is not harming “our” cause to show young people how to treat themselves, especially considering the lack of healthcare options they currently have. And considering the shame placed on victims, sex, and drugs in our society, it is amazing that young people even ask for and receive help.

    As to the term “intoxicant” you used when referring to recreational use, I’m not sure I would use that term to describe marijuana, especially considering all the health benefits that can be obtained from the drug. Heck, if it is determined that cannabis not only cures cancer, but keeps it from developing (like a cancer vaccine), they’ll probably start pumping it through the public water supply.

    So you see, our community is large and includes all kinds, and when you put down one of us (whether it be with the term “halfwit frat boy” or “chuckleheads”), you kinda put down all of us (including your younger self, by the way). The Weed Blog doesn’t have an R rating, nor do you have to be a certain “legal” age to be a part of the community.

    I hope that I have displayed enough maturity here to turn your sad frown upside down. And might I suggest that if you don’t want to be part of the kegger scene, quit spending so much of your time on articles about bongs.

  16. want and need are two different things I’ve never needed a bong either but theres several I want. just not this one.

  17. thanks I appreciate that. It’s rare in this day and age for people to be so eloquently forthcoming on the internet. Your display of intelligence is astounding. you deserve a round of applause. c’mon folks clap for Jeff… folks? anybody? just me then huh well that counts for something. kudos to you jeff. kudos

  18. If my point isn’t clear I will refer to the rest of the comments on this post and the amount of maturity shown here. I’d liken this to a keg stand honestly… it’s quite sad.

  19. grow up? the reason my kids know about Cannabis is not because they saw it on the internet it’s because I told them about it but thats beside the point my point is that we should do our part responsibly by not allowing children easy access to intoxicants until they are legally adults. it’s not that there is a magic age that makes you responsible or more mature it’s that there is a legal definition between children and adults and as much as children want equal rights very few kids today are responsible enough to be considered to be adults at the age of 18. if you disagree with me thats fine it’s just my opinion garnered from my view of current world events. as far as a sprite bottle breaking the movement… I didn’t say that….I imply it is a cheap disposable method often used by people with no access or ability to purchase or keep a permanent piece around therefore making it very attractive to the underage smoker or smoker in less than pot friendly areas therefore making it an illegal act. I have no problem with mature adults smoking marijuana I enjoy it myself as much as I can. I have an issue with things like this making responsible mature adult smokers look like chuckleheads to the rest of the country. that sir is my issue nothing with this being creative I will admit to using one of these on many occasions in my youth but back then I didn’t have the internet to use as a source I figured it out on my own like I was supposed to. that being said I was a child then I’m a man now and I’ve put away childish things. that’s just me you can smoke out of a sprite bottle like a halfwit frat boy if you want.

  20. I was replying to your comment and the one above it at the same time I didn’t mean to imply you at fault I’m terribly sorry to have victimized you again.

  21. It’s so dumb that you can’t spell dumb or retarded.
    Use that wasted time to learn how to spell and probably read.

  22. Robert Patrick Mckeever on

    Another way,no water needed,take a hair coloring plastic bottle,clean and cut a hole in the bottom,the same size as a plastic hose coming off of an aquarium air pump,stick the hose into the end,roll a long joint,stick it in the Cone end of the platis bottle cap,lite it,stick the cap back on and just plug it in to take a hit as long as you can stand! just be carefull when the joint gets near the end of the cap!

  23. I’m confused. Why do you think that I had anything to do with posting this article? Or sending it to your feed? And who is the “kid”?

  24. oh fucking grow up man just cuz they show this on facebook doesnt mean ur kid doesnt already know…i dont think our marijuana movement is gonna be made or broken by a sprite bottle…

  25. Thanks for making me feel dumb! Not really :) I’ve never heard of this, and I’m gonna try it. Oh and I’m 28

  26. this article just showed up in my feed today so the kid is maybe just responding to this now as I am…I agree with both why you wasting my time with this and also shit man I made versions of this back in the early 90’s and they haven’t got shit on a good old gravity bong… live in the past much. this is an invention for teenagers who can’t get in to proper smoke shops… so let me ask you this why are you posting methods that are A.) archaic B.) aiding underage smokers that will eventually harm our cause?

  27. I like using a potato. When you’re done medicating you can cut it up and fry it up. Cooking also helps cover up the odor. -peace-

  28. This article is from 2012… Dude, why you livin’ in the past? And, I’m sorry, but did you have something else BETTER to do? (Also, just a hint, the caps lock key is to your left, by your little pinky.)

  29. Holy Shit, first time seeing this blog and reading this is like listening to myself. I pretty much do everything similar, from the cap in the freezer to keeping my bottle in the fridge.
    P.S. I may have you beat on the amount taken

  30. great guide! I myself would always prefer a real glass bong over a fake plastic one. I just don’t like the taste that it gives you when you hit it. These homemade bongs all taste like hot plastic! Yuck! Anyways if you want to purchase a real bong go to http://www.premiumbongs.com

  31. I love waterfull bongs. I usually make smaller ones though. I make a hole in the cap just big enough for a one of those small glass hitters to fit in then I attach a small length of tubing to the hitter once it is in the cap so that way the tubing goes under the water inside the bottle. I call it bubbling waterfall bong. Give it a try. Top the herb with some ear wax to really give it a kick. http://www.420friendsonline.com/page/earwax

  32. we don,t use the bong stem instead of it we use the aluminium foil, take a small piece of foil make it like the cap of plastic bottle make a kind of bowl on the upper side foil cap and drill it with tip of pen or needle put your weed in to it

  33. this is great!!!! waterfalls are the shit! and the part about exposing rookies is amazing too, i smoked with a kid who said he was a “big smoker” and how he smoked more than me, after one waterfall i left his house and he had called his mom and went to the hospital because he was so high and he thought it was laced… hahhaha but this is great and so are waterfalls! gravity bongs make me feel like im going down on a dick when i smoke them and bong water in your mouth is fucking horrible! WATERFALLS <3
