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.
