Glycerin bongs 16" Freezable Glycerin Straight Tube
with Double Matrix PercsExperience the absolute pinnacle of cooling and filtration engineering. Standing at a towering 16 inches tall, this straight tube powerhouse pairs a deeply chilling detachable glycerin chamber with a heavily fortified core of stacked double matrix percolators. Forged from exceptionally durable 5mm borosilicate glass, it harnesses a wide circle base, fixed downstem, and a massive 18mm joint to deliver high-velocity, sub-zero hits with absolutely zero drag. Phoenix Star's Modular Sub-Zero Technology
1Quick-Freeze ModularityUnclip the heavy-duty 34mm joint to isolate the top glycerin chamber. Place it in the freezer for 1-2 hours for a deep, non-toxic freeze that vastly outperforms standard ice cubes.2Zero Ice-Melt FloodingTraditional ice catches melt and overfill your bong's water base. Our enclosed glycerin coils stay icy for extended sessions without ever leaking or disrupting your perfect water levels.3Dual Matrix Pre-ConditioningBefore the smoke even hits the freezing coil, the twin stacked matrix percs shred the vapor into millions of microscopic bubbles, stripping out maximum heat and harshness.Key Advantages

How do the double matrix percolators work together?As you pull, smoke enters the bottom matrix perc and is immediately forced outward through its 360-degree grid, shredding it into bubbles. These bubbles then travel straight up into the second stacked matrix perc, where the process is repeated. This dual-stage gauntlet multiplies the water surface area exponentially, providing massive filtration before the smoke even reaches the freezing chamber.Why is the 18mm joint paired with a fixed downstem?In a towering 16-inch bong with dense double percolators, maximizing airflow is critical to prevent heavy drag. The permanently welded fixed downstem guarantees a 100% airtight seal (no leaks), while the extra-wide 18mm intake allows massive volumes of air to flood into the pipe, making hits effortless and smooth.How do I properly freeze the glycerin chamber?Unfasten the keck clip connecting the 34mm joint. Remove ONLY the top glycerin coil segment and place it flat in the freezer for 1-2 hours. Do not freeze the bottom straight tube base while it has water inside, as freezing water expands violently and will crack the glass base.What makes the 34mm modular joint so secure?The connection relies on a massive, heavy-duty 34mm precision-ground frosted glass joint. When the two glass pieces lock together and are secured with the included plastic keck clip, it creates an incredibly rigid, airtight vacuum seal that eliminates wobbling entirely.What is the best way to clean the double matrix percs?Thanks to the modular 34mm joint, you can separate the glass bong in half. For the bottom chamber housing the percs, pour in 91%+ Isopropyl Alcohol and coarse sea salt. Plug the 18mm joint and the 34mm top opening, then shake vigorously. The alcohol melts the resin, and the salt physically scrubs through the fine slits of the matrix grids. Rinse with warm water.
