Take a peak inside the mad minds of Micah Evans and Austin’s GRAV! Both known for delivering nothing less than exceptional, this 18-inch Upline will have you and your crew drop-jawed with awe. Crafted from scientific borosilicate glass, this original Upline water pipe combines the power of hydrodynamics, directional airflow, and gravitational diffusion for impeccably smooth inhales. Smoke descends from the unique Dewar’s joint, through a bed of water, and bubbling upward through a ladder-like stack of forced restrictionpercs. It ends its journey through an arched neckline with a contoured mouthpiece -- the entire piece designed for comfortable use as much aspowerful delivery. Thick glass construction, a widened base, and a two-prong joint add to the long lifespan of this experimental luxury. It’s a pipe your favorite mad scientist would appreciate. The spine-ish silhouette is also available in a 12-inch size if you’re not ready for the extra six inches of shockingly smooth smoke!Please Note: decal colors selected at random.

Features of this Water Pipe

Water Pipe
This piece is powered by hydrodynamics that smooth and cool every inhale.
Straight Tube
This pipe features a sleek, minimalist silhouette. Its clean lines streamline the travel of smoke without any added chambers or contours between the joint and mouthpiece.
Dry Herb
This piece works with dry herbs! Dry herbs are the pure plant form, best when paired with a quality grinder for evenly cut material.
14mm Joint
This piece features a standard 14mm joint, suitable for all 14mm accessories. Use this measurement to match pipes with the best slides, nails, domes, ash catchers, and pre-coolers.
This stemless (a.k.a. 'direct inject') water pipe has no downstem. Airflow instead travels directly through the open joint.
90° Joint
This piece features a 90° joint. Choose ash catchers, pre-coolers, and other accessories made at the same angle as your water pipe.
Female Joint
This piece features a female joint. Pair it with a male accessory of the the same diameter for a soulmate match. Use an adapter to attach a female accessory to this piece.
Scientific Glass
Pardon me while I pop on my lab coat -- like the "laboratory", not the attention-hog dog next door. This pipe boasts high grade construction and a crisp, laboratory-like silhouette.
Bent Neck
This pipe features a bent neck for casual pulls that don't make you strain to lean over the neck of your pipe. The comfortable effect also offers a stylish, modern look.
This product features a collaboration of great minds, combining the talent of popular artists, brands, and celebrities. My human and I combine our genius all the time -- he throws the frisbee, I bring it back. How collab is that? We've got to start charging all those drooling Labradors for such an epic show.
Ladder Perc
Invented by Micah Evans of Grav Labs, the ladder perc is the signature engineering element of their Upline collection -- famously dubbed "Advanced Perconomics." A series of restricted chambers are stacked in a ladder or spine-like silhouette where smoke gets diffused through each individual chamber.
Dewar's Joint
This piece features a reinforced joint for added durability against butterfinger paws and powerful tails.
I've got my Boo Paw of Approval on this bulldog-strong glass. This piece is crafted with strong borosilicate glass that's known for being durable against breakage, resistant to extreme and quick-changing temperatures, and easy to clean.

    Simply the best

    Yeah, it looks amazing, but that wouldn't be worth it if it doesn't rip. And, boy does it rip!

    State of the art bong

    Nothing short of amazing, this bong delivers incredible hits and is a thrill to watch other people use. A scientific bong at its best!

    The Dewar's joint is what makes this a great bong to smoke out of. The amazing craftsmanship put into the glassware is what makes it intriguing in the first place. All around, it's a winner.

    Such a beautiful piece

    The second I saw this I knew I had to have it. I was a bit hesitant to order it online since the glass needs to be shipped carefully. Fortunately, DopeBoo knows what they're doing and packaged it perfectly. Not to mention it arrived in only a few days. Now I have it and it is the biggest pleasure to smoke out of this when I'm relaxing at home. Sometimes my neighbors check in just to see if they can use it.

    Big and beautiful

    This 18 incher is just what the doctor ordered when I'm looking for big, cool hits. It has a permanent place displayed on my shelf when it's not in use, it's a real work of art.
