A gravity bong, also known as a geeb, is a cannabis consumption method that uses two empty plastic bottles to funnel smoke through water and push it into the consumer’s lungs. Gravity bongs work by submerging a small bottle with a bowl of cannabis on top in a larger bottle or bucket of water. While lighting the cannabis, slowly draw the bottle out of the water to fill with smoke from the burning cannabis. Unscrew the lid, put your mouth over the bottle’s opening, and push the bottle down to let gravity propel the cannabis smoke into your lungs. Voila!
Do gravity bongs get you higher?
The short answer is yes. Gravity bongs force heavily concentrated smoke into your lungs, filling them to capacity beyond the average hit from a pipe or joint. When you inhale the contents of the smoky bottle into your lungs, you are essentially breathing in the smoke from an entire bowl of cannabis in one go. For this reason, gravity bongs are certainly not for the faint of heart. A tried-and-true method of old school cannabis consumers, it delivers a powerful hit of THC that may be too much for an inexperienced cannabis beginner.
However, if you’re looking for a bit of nostalgia and feel like getting crafty with your cannabis consumption, here’s a handy guide to creating your own gravity bong using a few everyday household objects. (Disclaimer: Inhaling combustible materials from a plastic smoking device may be hazardous to your health. Proceed at your own discretion!)
Are gravity bongs worth making or buying?
If you’re new to cannabis or have a low tolerance, you probably don’t want to start with a gravity bong. But for intermediate to advanced consumers, making a gravity bong is a fun, easy DIY project that ensures a fast delivery of your favorite strain. Not the crafty type? You can buy gravity bongs to add to your collection of hardware and bust one out whenever you want a unique and potent smoke session.
Are water bottles safe to use?
Many homemade bongs or smoking devices are made using single-use plastic bottles, which contain PETE or PET (polyethylene terephthalate) that can release chemicals when heated (like how the water from a bottle that’s been left in a hot car can taste odd). You may pull these chemicals into your lungs when applying heat to your gravity bong.
Research is still being conducted on what sort of impact this type of exposure may have on your health. Many cannabis consumers prefer to use glass or silicone smoking devices and avoid plastic as a precaution. If you choose to make homemade gravity bongs and other smoking devices out of plastic materials, be aware of the risks and proceed with caution.
How to make a homemade gravity bong
First, gather the following items:
- Plastic bottle (any size, but 16-20 oz is ideal)
- Bucket or 2-liter plastic bottle
- Aluminum foil
- Box cutter or sharp knife
- Poking device
- Cannabis strains of your choice (at least one gram)
Gravity bongs can be a bit intimidating if you don’t know where to start, but the procedure is more straightforward than you might imagine. It just requires a little ingenuity, some creative efforts, and the determination to make it work, and in less than 10 minutes you can construct your very own gravity bong using materials you probably already have at home.
Wondering How to Make a Gravity Bong?
In college, when I first started smoking weed, I had a long period of discovering new and exciting ways of getting high. I went from a crappy aluminum spoon to a glass bong in a few weeks and then began a long campaign of experimenting with different vessels on a quest to make the ideal DIY bong. The results were questionable at best.
As building experimental smoking devices with friends escalated someone eventually suggested we make a gravity bong. At the time I had no idea what it was or how to make a gravity bong. But from the name and a brief description of how it worked, it sounded like we were going to get high AF, so I was down. The bong we made was not pretty by any means and not glass. We cut the bottom off a three-liter bottle and drilled a hole in the cap to slide the bowl into. We placed this bottle top into a 5-gallon bucket of water with only the bowl sticking out. When you held a lighter up to the bowl and raised the bottle out of the bucket, it filled with an enormous amount of smoke. We made a gravity bong.
What I did not understand at the time about a gravity bong is that despite all the water you see, that massive hit stored up, it’s uncooled and unfiltered. It was harsh for sure, and I thought I was going to die, but I just got extremely stoned instead. I was blown away by how hard and intense the hit was and how fast you could inhale it when you used the pressure from the water. Now I understood what the big deal was, but I could not possibly imagine smoking out of one all the time.
Enter the Gravitron
Little did I know years later, I would encounter the gravity bong again, but in a much different form. The Gravitron is what put the Grav in Grav and was the debut pipe made only by them. The original waterfall was more of a contraption that had a rotating water vessel, and a stand that it would sit on. Eventually, it would evolve into a much more traditional and modernized all glass gravity bong that would look like the glass on glass wine bottle style Gravitron we have today.
The wine bottle model is what I hit, and I was thoroughly impressed by how much easier to use and effective this model was. Like the tagline says, you’ve never made one like this. The Gravitron XL has an airtight seal around the bowl that makes a massive difference for creating enough adequate suction to cause smoke to fill the chamber. When you pull the bowl and lower the bottle top back into the water, it forces the smoke up into your lungs effortlessly.
2 thoughts on “What is a gravity bong and how do you make one?”
Do gravity bongs get you higher? Speaking from personal research and testing – much denser smoke in a quicker time. Usually would mean a stronger but shorter high.
Gravity bongs although are available in the market commercially, but still the home made ones are a bit different from these. You can get the home made version from your local pot seller, and I think the aroma and smell is different from the commercial ones, I like this better.
