The Milkyway Expansion is a 14-inch beaker bong fitted with a Collins percolator and finished in a single-layer sandblast that reads as futuristic geometry, built on thick, durable glass and shipping with a 5.5-inch downstem and bowl. It is the design-forward end of Milkyway's beaker lineup.
Where the Kevlar is about brute durability, the Expansion is about form. The single-layer sandblast etches dimensional, futuristic patterns across the tube, so the piece plays with space and structure instead of just color. It catches the eye the way a designed object does — you register the texture before you register that it is a bong.
Under that finish sits a Collins perc — a horizontal bar diffuser that spreads smoke across a row of slits — for smooth, even filtration. It is a beaker that looks like a design object and filters like a considered one, which is a harder pairing to pull off than either alone. Milkyway treats the aesthetic and the function as equal parts of the brief.
Specs
- Height: 14 inches (35.6 cm)
- Weight: 1.3 kg
- Joint: 14mm
- Percolation: Collins perc
- Finish: single-layer sandblast with dimensional pattern work
- Included: 5.5-inch downstem and bowl
The 1.3 kg weight tells you this is built on substantial glass, not a thin novelty tube. The 14mm joint is the versatile everyday standard, easy to match with replacement bowls, and the included 5.5-inch downstem and bowl mean it is ready to run out of the box. The Collins perc is the functional centerpiece, tuned to diffuse without choking the draw.
This is for the smoker who wants percolated smoothness and a piece that looks intentional on a shelf. The Collins perc suits anyone who prefers even, cushioned draws over a raw straight-through hit, and the sandblast styling appeals to people who want their glass to have a point of view rather than blending in.
Because it comes with the matching downstem and bowl, it is ready to run out of the box with no extra sourcing. It fits a modern setup where the bong is part of the room's aesthetic, not something to hide — the kind of piece that looks deliberate next to designed furniture and other considered objects. If you want one everyday beaker that pulls smooth and looks like you chose it on purpose, this is it.
The Collins perc is the functional core — its horizontal bar of slits diffuses smoke widely and evenly, cooling each pull without the drag some denser percs add, which makes for a smooth, consistent draw. It is a workhorse diffuser that heads trust precisely because it balances smoothness and airflow rather than trading one for the other.
The single-layer sandblast is the aesthetic hook, giving the piece a futuristic, textured look that stands apart from Milkyway's color-forward tubes. Thick, durable glass keeps it sturdy for daily use, and the included downstem and bowl mean no extra sourcing or guesswork on fit. For roughly $165, getting both a quality perc and genuine design character in one beaker is a strong showing that most tubes at the price cannot match.
Sandblasting is a craft borrowed from art glass and industrial etching, where an abrasive stream carves texture and pattern into the surface — bringing gallery-object detail to a functional piece. It is a way to add depth and dimension that color alone cannot, and it gives production glass a tactile, considered quality.
The Collins perc, meanwhile, is a workhorse diffuser that heads trust for its balance of smoothness and airflow. Milkyway pairs the two here to make a beaker that argues you should not have to choose between a piece that performs and a piece that looks like it belongs in a designed space. It is the brand's more experimental side, and it fits the wider push in cannabis culture toward glass as intentional design. Keep it 21+, keep the water fresh, and the Expansion holds its own on both fronts.
Common Questions
What is a Collins perc? A horizontal bar-style percolator lined with slits that spreads smoke evenly for a smooth, cushioned draw without heavily restricting airflow.
Does the Expansion come with a bowl? Yes. It ships with a matching 14mm bowl and a 5.5-inch downstem, so it is ready to use out of the box.
Setup and Care
Drop in the 5.5-inch downstem and 14mm bowl, then fill until the Collins perc slits are just submerged — enough to diffuse without gurgling. Change the water each session to keep the draw smooth and the flavor clean. When resin dulls the perc, remove the bowl and downstem, add isopropyl alcohol and coarse salt, cap the joints, and shake to work the solution through the Collins bar; a short soak clears the slits. Rinse well before reuse.
The sandblast finish is etched into the glass rather than coated on, so it will not wear off with regular cleaning.
