GRAV® Slush Cup

GRAV® Slush Cup Bubbler (4" Borosilicate Glass Water Pipe — Assorted Colors)

Experience the triumphant return of a modern classic with the GRAV® Slush Cup Bubbler. Back by popular demand and reimagined for the celebrated GRAV® Sip Series, this functional masterpiece captures the whimsical silhouette of a frozen summer treat. Don’t let the playful design fool you—this bubbler is engineered for serious performance, packing an incredible amount of water filtration into a compact, handheld footprint that fits perfectly in your palm, cupholder, or coaster.

The Slush Cup is built for the "big rip" enthusiast. It features a reinforced cross-cut downstem that aggressively diffuses smoke through water, delivering hits that are as cool and refreshing as the drink it mimics. The recessed 14.5mm Dewar-seal joint sits flush with the upper rim, maximizing the internal chamber volume for massive smoke expansion. With its upgraded, heavy-walled straw and splash-proof angled design, it’s the definitive choice for the smoker who values top-tier durability and silky-smooth airflow.

This compact beverage-themed scientific hydro-vessel serves as an essential, high-utility expansion for your active glassware catalog. Outfitted with a 14.5mm recessed Dewar-seal female ground connection and an included matching 14mm male cup bowl, it establishes immediate out-of-the-box session readiness. Incorporating this GRAV® creation into your daily routine introduces a low-volume, rapid-clearing water circuit that pairs nostalgic cup design with smooth, splash-free draws.
