DIY $3.50 Mini-Bong Vape Pen Bubbler

People use bongs (aka water pipes) because they cool off the smoke and make it easier on your throat and lungs. Bongs work amazingly well with vapor too, but you hardly need a large or expensive bong for the amount that comes out of a vape pen. I came up with this design for my wife Felicity. Felicity has allergies and lung problems and can absolutely not smoke, but occasionally needs a quick hit of indica for panic attacks. She’s used my vape pens (with good CO2 oil and wax only!) but is always concerned about coughing. So, after running all over the place looking for the diamond-studded hole saw I bought for my somewhat-epic “How To Make Your Own Bong” article, I was finally able to put this all together. The balsamic vinegar was even on sale, so the parts for one cost less than $4!

Here’s what you’ll need:

  • About 6″ (or 15 centipedes) of thick hose that snugly fits the mouthpiece of any vape pen you happen to have. I just happen to have two very common ones and a piece of 3/8″ ID air hose happened to fit them both. Take your clean mouthpieces (by themselves, if possible, to avoid embarrassing questions, which you could always answer with “science project”) down to your local hardware store to find the right hose. The stuff I got was $0.99/foot, the minimum they will sell you.
  • A diamond-tipped hole saw that will fit the OD (outside diameter) of the hose you bought. It will probably be around 5/8″, so here’s a random listing on Ebay selling them for less than $3 apiece.
  • Star brand balsamic vinegar. The tiny (250 ml.) bottle I bought is the perfect size for use with a vape pen or for stealth, but they have larger (and more stable) sizes available if you want to actually smoke out of it.

The steps are fairly simple:

  1. Open the bottle, pry off the plastic insert that lets the vinegar flow smoothly onto your salad, and pour the contents into another bottle (it’s food, don’t waste it!). Recycle the cap and the insert.
  2. Fill the bottle with cold water, and then drill the hole using a battery-powered drill at high speed using eye protection on a plain portion of the upper surface (away from the embossed logos) so that the hose will end up at about a 45° angle. Use the safety instructions I wrote up here!
  3. Wash out the bottle carefully and remove all the glass powder and etc.
  4. Stick the hose in the bottle. If it’s not a tight fit, wrap it with some electrical (or better: silicone repair) tape until it stays in nicely.
  5. Now fill it with water up to the hole, stick your vape pen in the end, hit the button, and inhale!
  6. If you’re a smoker and not a vaper, I recommend a 3/4″ hole, a grommet to fit, and a 14mm downstem that nicely fits your bottle of choice. But in an emergency, you could stick the proverbial trumpet mouthpiece in/over the end.

So of course I gave Felicity the first shot at this thing. She took a huge hit and didn’t cough at all. Then I took a huge hit and only coughed twice, but I didn’t really even feel the vapor in my throat the way I usually do. Such a big hit usually triggers a full-on coughing fit for me, so I think it was quite a success!

About Old Hippie Old Hippie is a father of two boys and thankfully living in California where all this kind of thing is legal. He started smoking marijuana in 1967 in high school, experimented with mind-expanding drugs of all kinds, and then straightened out 15 or so years later to become an airplane pilot. After being diagnosed with depression in 2000, he lost his job and most of the following decade to prescription medications (such as antidepressants) which sapped his energy and will. Finally, a chance conversation with a friend led to a doctor’s recommendation for medical marijuana (MMJ). This changed his entire life, health, and outlook for the better. is his continuing story. It’s also his way to provide experienced advice on using medical marijuana effectively and responsibly, as well as advocacy, activism, and support for others. Old Hippie teaches about safe use of cannabis edibles, Canna Caps, vaporizers, dosing, and even microdosing.


I did something similar with a glass waterpipe and vaporizer I already have. I just needed to get a glass on glass piece to replace the standard bowl that came with it. Using a power whip style vaporizer (Vapir Rise Ultimate), I was easily able to connect the whip to the piece. I’ll link off to another site to show you a couple of images of the waterpipe as well as the piece I used for the conversion.
It sure is a nice change taking the vapor in via a nice glass piece than it is from say a plastic bag (Volcano – my main vaporizer).

Peace be with you from Kevin 🙂
