BigFun! Sublime Borosilicate Gravity Bong – 14 mm – 9″

First pull, and the vapor cloud spirals like a mini‑storm—welcome to the BigFun! Sublime Gravity Bong.

What It Is

The BigFun! Sublime is a gravity‑style bong built from 100% borosilicate glass, standing 9 inches tall with a 3½‑inch base. It sports a 14 mm joint that mates with standard bowls and ash catchers, meaning you can swap parts without a hassle. Its compact 9″ × 3½″ footprint fits comfortably on any tabletop without crowding your other gear. This piece combines a bottle‑inspired silhouette with a full water‑filtration chamber, delivering cool, smooth hits every time.

When you pull, the gravity action pulls the smoke through the water column, creating a thick, dense cloud that rolls off the rim. The design is straightforward—no extra gadgets, just pure glass and water working together.

Why You’ll Love It

• Clean, cool hits: water filtration and diffusion temper each draw, so the smoke feels silky and less harsh.
• Durable construction: borosilicate glass resists thermal shock, so daily sessions won’t crack the piece.
• Easy to maintain: a quick rinse with isopropyl and salt clears residue, keeping flavor fresh.
• Swap‑friendly design: the 14 mm joint fits most bowls and accessories you already own.
• Eye‑catching aesthetic: the bottle shape and crystal‑clear glass make it a centerpiece for any collection of glass bongs and water pipes.

How To Use It

Fill the chamber until the percolator slits are just covered, pack a loose medium into the bowl, then pull slowly to create the vacuum. Change the water daily and give it a deep clean weekly with 91%+ isopropyl and coarse salt to preserve flavor.

Keep the piece upright on a stable surface and avoid rapid temperature shifts; this helps the borosilicate glass stay intact for years.
