GRAV 5" Upline Hammer Bubbler

Are you prepared for “Advanced Perconomics”? This futuristic design comes from the step-ahead engineers at GRAV paired with the mad scientist mind of Micah Evans in the first of its kind Upline collection. Applied to a variety of shapes and sizes, the essence of the Upline is a series of stacked restrictions that each act as its own percolating station in a spine-like silhouette. Watching the bubbles flow through this unique creation is just as badass as you might imagine. Through the combined effects of directional airflow, gravitational diffusion, and hydrodynamics--you’ll feel like you’ve stepped into the future with the incredible clouds this device can deliver. Possibly THE most effective push-bowl bubbler out there, this thick glass pipe is further enhanced with a diffused downstem, carb construction, and a layback flute mouthpiece. You won’t want to stow such a sophisticated design away; you’ll find yourself proudly passing it around for friends and displaying it like the artistic masterpiece it truly is.

Features of this Water Pipe

Water Pipe
This piece is powered by hydrodynamics that smooth and cool every inhale.
Bubblers are the perfect blend between water pipe filtration and hand pipe portability. A small amount of water washes away the harshness of inhales in a handheld size.
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.
Fixed Downstem
Don't worry, they didn't give this pipe the ol' snip-snip. Fixed downstems extend from the joint of your water pipe into the water as a small tube to maximize diffusion.
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.
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.
This piece includes a carb -- the small hole that channels fresh outside air into your pipe for a cooling, soothing effect. Place your thumb on the carb to allow your pipe to fill with smoke before letting go for a refreshing clearing action.
Diffused Downstem
This pipe features a diffused downstem -- the simplest percolator form. It's essentially a glass straw that stretches from joint to water on the interior of the water pipe. Slits at the end of the downstem create diffusion to soften and cleanse each inhale through hydrodynamics.
