There’s an age-old joke in the world of cannabis consumption that says when you give a group of potheads some marijuana with nothing to smoke it with, they’ll turn into engineers. But what happens when you give a bunch of engineers some pot?

You get the next generation of cannabis consumption technology.

Now, I have always been a fan of GPen devices; I’ve reviewed the GPen Connect. I’ve used PuffCo, I’ve tried Dr. Dabber, I’ve tried off-brand e-nails and several sub-par wax pens and battery-operated dab straws. Most of them are sitting in an empty drawer in my desk, a virtual graveyard for technology that didn’t deliver.

A couple of months ago, as a podcast host of “A Tech Moment” on Cannabis Tech, I had the opportunity to interview B-Real, frontman for Cypress Hill and visionary behind the Dr. Greenthumb, California cannabis company.

An heirloom device, built with quality, design with elegance, the Stündenglass Gravity Hookah is the last bong you’ll ever need to buy.

As a perk for lining up that interview, Grenco Science, makers of GPen and the Stündenglass, sent over a care package of Dr. Greenthumb branded GPen devices.

And let’s just say – my mind was blown.

Good-Bye Cheesy Gravity Bong

Most old-school cannabis consumers have a story they tell about the gravity bong they built with nothing more than a bucket of water and a plastic bottle. The entire concept behind these contraptions is that the water does the hard work – all the smoker needs to do is light the bowl, slowly lift the bottle, and the suction created by gravity and the void in the bottle draws the smoke. Cooled by the water, gravity bong hits are smooth and generally quite powerful.

However, unless you’re still living in your mom’s basement or at a nearby frat house, no one wants to have an old trash can and an empty 2-liter of Pepsi sitting in their living room.

Allow me to introduce… the Stündenglass Gravity Hookah. As seen on several celebrity podcasts, including Seth Rogan, Wiz Khalifa, and B-Real, this device blows every other cannabis-consuming device out the window. Although a little on the pricey side, there is nothing about this feat of cannabis engineering that disappoints.


The Stündenglass Gravity Hookah – The Specs

So before we talk about how it works, let’s talk about the overall design and how it ships. The Stündenglass Gravity Hookah ships in a specially designed case that fits all the little pieces and parts. I won’t lie; when I unboxed this bad boy – I was a little intimidated. This is the first bong I’ve ever owned that actually came with a schematic.

Fortunately, the Stündenglass ships with everything you need – just in case. Not only do they send the schematic that shows you how it all goes together, but they also send all the little O-rings, plastic pieces, and things that ‘could’ go bad over time. The device is mostly assembled; all you have to do is put the major pieces together and add water.

Assembly is quick and painless. All of the pieces and parts are either threaded and screw into place or – in true Grenco fashion – they are magnetic, so they simply snap into place.

Get ready to impress everyone.

Versatility is the Name of the Game

One of the biggest benefits of the Stündenglass is its ability to smoke just about anything. In the box, the device ships with a glass bowl for smoking cannabis flower and a sheesha bowl that allows consumers to smoke tobacco – if you genuinely want to use it as a hookah. If you are a concentrates consumer, then you’ll have to spend a little more money to order the GPen Connect but believe me when I say – you won’t be disappointed, it’s worth it.

Made out of anodized metal with a 10-year warranty, the Stündenglass is an heirloom device that brings elegance and sophistication to cannabis consumption. You will want to keep this gravity bong on display, but be prepared to answer, “Oh my God – what is THAT?!” every time someone new walks into your house.

Then you can really blow their minds…

The Design and How it Works

When I saw how the Stündenglass works, I immediately thought, “Wow, the design IS the technology!” Per their website, the 360-degree rotatable mechanism “uses kinetic motion activation, cascading water and opposing airflow technology to deliver the most powerful and unique smoking experience.”

In other words, after lighting the bowl, or activating the Connect, when you rotate the globes, gravity pulls the water through the percolators into the lower globe. The rotation allows air to pull the smoke or vapor into the upper globe. Rotate it one more time, and the airflow forces the smoke collected in the globes through the up-stem, through the hose, and right to your mouth.

Because the device does the draw for you, the consumer can control just how much they inhale. By holding your lips away from the end of the mouthpiece, you can take as much or as little of the vapor/smoke as you want. On the flip-side, if your goal is to get wrecked, put your lips on the mouthpiece and breathe in deeply to take in all the vapor.

Be aware, during my conversation with B-Real – Dr. Greenthumb himself called the Stündenglass “The Devastator.” In fact, he said, “If you want to test your level of ‘stoner’ – this is the device that will do it.”

Please… Drink the Bong Water

While most people are learning about the Stündenglass from celebrity podcasts, I learned about the device when a PR rep sent me a video of a mixologist using the Stündenglass. In the video, he “smoked” alcoholic beverages by burning wood chips through the globes.

Immediately, my mind started racing – what if we could infuse mixed drinks with cannabinoids using the Stündenglass? So, during our annual 4/20 week celebration, we put the Stündenglass to the test with “Smoked Margaritas.” Let me tell you – we were all impressed.

Rather than filling the globe with water – we filled it with margarita mix, tequila, and triple sec. Then, using a high-quality Clementine Live Resin – we used the GPen Connect to do a few dabs. Each hit and each rotation of the globes, the vapor from the Clementine filtered through the alcohol.

Now let’s think about this from a physics perspective. Essentially, you’re taking a solid (the extract), heating it to a vapor (using the GPen), then cold-filtering the vapor through a blend of alcohol where it re-condenses. Once everyone has had their dab, remove the globe, pour the thoroughly blended margaritas on ice and watch your guests light up when they realize what just happened.

What’s the result? You end up with dabs that taste like margarita and cannabis-infused, drinkable ‘bong water.’ Our test used high-terp, Clementine resin – the orangey, sweet flavor came through in the blend, and you could actually taste the cannabis in the glass. Not only that, but you could also feel the wax on your lips as you drank.

We quite literally smoked our Margaritas and drank our weed.

Mind. Blown.

The Bong You’ll Love to Clean

As a well-versed cannabis consumer, the first thing I think about when we shop for a new bong is – “How easy is it to clean?” I know that if it’s hard to clean or a pain-in-the-ass to take apart – it’s not going to happen very often. Nobody wants to smoke from a grungy bong. Eww.

While I feel like you’re going to think I’m just trying to play up the device, so you’ll buy one – I can honestly say, I look forward to cleaning my Stündenglass. This is quite simply the easiest device to clean that I’ve ever reviewed. As I mentioned earlier, everything either screws together or snaps into place with a magnet, so taking it apart is super simple.

I use a 9 x 9 glass baking dish; put all the stems, percolators, and removable pieces in the dish and cover the items with isopropyl. While they soak, I use a cotton swab and alcohol to clean the mechanism in the Stündenglass. Then, I use a little more alcohol and a paper towel to wipe out the globes.

*Pro Tip: Rather than using massive amounts of alcohol, after I clean all the individual stems and pieces, I will use the alcohol in the baking dish to rinse the globes. Then, rather than simply dump it, I will use a funnel and pour the alcohol into a container I have labeled as “dirty.” Now, obviously, you won’t want to use this to disinfect anything – but it can indeed be reused to clean your pipes and other smoking accessories.

Very Few Drawbacks

The Stündenglass is versatile, well-built, and above-average in the design and functionality department. But, like all things – there are a few areas to note when you’re considering making a substantial purchase like this.

  • The Price – Ok, I get it – not everyone has an extra $600 laying around to buy a cannabis smoking device. It is an investment, no matter how you look at it. I’ll be the first to say that had Grenco Science not sent me the device, I probably wouldn’t have bought it. But now that I have it – I won’t give it up, and I would likely replace it if something happened to it.
  • The Reclaim – This is my only complaint about the GPen Connect. When smoking concentrates, the reclaim drains from the device and into whatever device you’re using. In this case, the reclaim pools in the channel and, so if you’re using it regularly, plan to clean it out no less than once a week, or the entire thing will get gummed up.
  • The Hose – I do not recommend using the hose with any kind of ‘smoke.’ The vapor from dabs is fine, but smoke tends to adhere to the hose and leave a nasty smell and flavor. If you plan on smoking flower or tobacco, I recommend removing the hose and simply inhaling right from the up-stem.

The Long and Short of It

The pros far outweigh the cons of this device. Although it’s a significant investment, this device will likely last you a lifetime. Sure, you may need to replace a few pieces here and there, but the simplicity of the design and the versatility of functionality make it well worth the price.
