Kraken Bong by Hemper — Sea Monster Turned Smooth-Hitting Glass Piece
The Kraken Bong is a borosilicate glass bong by Hemper that packs an inline percolator into a compact 5.7-inch (14.5 cm) frame — small enough to stash in a backpack, sturdy enough to survive your coffee table. Made from 5 mm thick transparent blue borosilicate glass, it filters and cools your smoke through a built-in inline perc, delivering noticeably smoother draws than any unfiltered pipe of similar size. If you want proper water filtration without dedicating half a shelf to glassware, this is the piece.

Why the Kraken Bong Deserves a Spot on Your Shelf
Most bongs under 15 cm are glorified pipes with a water chamber bolted on. They bubble, sure, but there's no real diffusion happening — just noise and splashback. The Kraken Bong is different because Hemper actually fitted an inline percolator inside that compact body. An inline perc sits horizontally in the base of the chamber and forces smoke through multiple slits before it reaches the water. That means more surface contact between smoke and water, which strips out more heat and particulate. The result: a draw that's cooler and less harsh on your throat than you'd expect from something this size.
The 5 mm thick borosilicate glass is the same material used in lab equipment — it handles thermal shock far better than soda-lime glass and won't crack if you rinse it under warm water after a cold night. The transparent blue tint looks sharp without hiding the water level, so you can always see exactly how much water you've got in there. One honest note: at 14.5 cm tall, the chamber volume is limited. You're not going to get the same volume of smoke as a full-size beaker bong. But that's the trade-off for portability, and for solo sessions or quick hits, the Kraken is spot on.
We've had a fair few customers come in looking for a "travel bong" — something that won't shatter the moment it leaves the house. The Kraken's thick glass and low centre of gravity make it one of the sturdier options in that size range. It's not indestructible, obviously — it's still glass — but it feels solid in the hand. There's a reassuring weight to it, about what you'd expect from a decent pint glass.
How to Use the Kraken Bong
- Fill the bong with water through the mouthpiece. You want the water level just above the slits of the inline percolator — roughly 1-2 cm above the perc. Too much water and you'll get splashback; too little and the perc can't do its job.
- Pack your bowl loosely. Don't compress the material — airflow is everything with a small bong. A light, even pack lets the inline perc work properly.
- Hold the bong upright, place your mouth over the mouthpiece, and light the bowl while inhaling gently. You should see bubbles forming evenly across the inline perc slits.
- Once the chamber fills with filtered smoke, remove the bowl to clear the chamber and inhale.
- After your session, empty the water and rinse with warm water. For a deeper clean, use isopropyl alcohol and coarse salt — pour both in, cover the openings, shake for 30 seconds, then rinse thoroughly. Do this at least once a week if you're using it daily.
Complete your setup with a proper grinder — evenly ground material makes a real difference in how smoothly the Kraken's inline perc pulls. A set of pipe cleaners or a bottle of bong cleaner will keep that transparent blue glass looking sharp between deep cleans.
Frequently Asked Questions
How much water should I put in the Kraken Bong?
Fill it until the water sits about 1-2 cm above the inline percolator slits. You'll see the slits through the transparent blue glass. If water reaches your lips when you tilt it, you've overfilled — pour a bit out and test again.
Is 5 mm borosilicate glass durable enough for regular use?
Yes. At 5 mm thick, borosilicate glass handles daily use and temperature changes well. It's the same material used in laboratory glassware. That said, it's still glass — a drop onto tiles will crack it. The low height (14.5 cm) and thick walls make it sturdier than taller, thinner pieces.
What does an inline percolator actually do?
An inline perc is a horizontal tube with slits cut into it, sitting inside the base of the bong. Smoke passes through these slits and breaks into smaller bubbles, increasing the surface area that contacts the water. More contact means more cooling and filtering. You get smoother, less irritating draws.
How do I clean the Kraken Bong's inline percolator?
Pour isopropyl alcohol (90%+) and a tablespoon of coarse salt into the bong. Cover the openings, shake vigorously for 30-60 seconds, then rinse with warm water. The salt acts as an abrasive to scrub residue off the perc slits. Do this weekly for best results.
Is the Kraken Bong too small for sharing?
It's built for solo sessions or sharing between two people. The 14.5 cm chamber doesn't hold massive volumes of smoke, so passing it around a group of four means frequent repacking. For group use, a taller bong with a bigger chamber works better — the Kraken shines as a personal piece.
Can I use the Kraken Bong with concentrates?
The Kraken Bong comes set up for dry herbs with a standard bowl. To use it with concentrates, you'd need a compatible banger or nail attachment that fits the joint size. Check the joint diameter before buying an accessory.
How does the Kraken Bong compare to a standard beaker bong?
A standard beaker bong of similar height typically has a simple downstem with no percolator. The Kraken's inline perc provides noticeably better diffusion and cooler smoke. The trade-off is a slightly more complex shape to clean. For filtration quality at this size, the Kraken wins.
