Your bong hits harsh by the third pull. The water's doing something, but not enough. You've heard about percolators, but there's one design that stands out from the rest, literally punched full of holes. Meet the Swiss perc, named after its resemblance to Swiss cheese and engineered to deliver some of the smoothest, lowest-drag hits you'll find in any online headshop. This isn't your basic downstem setup. The Swiss cheese bong design represents a breakthrough in glass engineering, where what's missing from the glass creates better function than traditional percs. Whether you're a flower enthusiast or concentrate lover, understanding how these hole percolators work helps you appreciate why they've become a favorite among smokers who care about both performance and design.
What Makes Swiss Percs Different?
Think of most percolators as obstacles that smoke passes through slits, holes, or chambers that force diffusion. Swiss percs flip that concept. They're barriers that smoke and water move around.
The design features welded holes built directly into the tube of your bong or dab rig. When you pull, smoke and water navigate around these strategically placed openings, generating bubbles and cooling your hit. The result? Unique filtration that creates massive amounts of surface area for smoke to interact with water, without the restrictive drag you get from traditional percs.
The Engineering Behind the Holes
Each hole in a Swiss perc acts as a bubble generator. As smoke rushes through the chamber, it splits around these openings, creating turbulence that breaks smoke into smaller particles. More surface area means better cooling. Better cooling means smoother hits that preserve flavor instead of scorching your throat.
The compressed chamber design keeps airflow moving efficiently. Unlike bulky percs that can trap stale air, Swiss percs maintain momentum from pull to clear. That's the secret to their signature low-drag function.
The Origin Story: Nate Dizzle's Innovation
Swiss percs weren't always industry standard. In the late 2000s, glassblower Nate Dizzle set out to solve a problem: how to create a percolator that delivered incredible flavor and looked pristine.
Traditional percs at the time often compromised one for the other. Nate's prototype compressed the chamber, leaving minimal room for air to stagnate. This created that distinctive low-drag smoke that became the Swiss perc's calling point. The design looked spectacular like a piece of functional art, while delivering performance that matched its aesthetics.
Today, Nate Dizzle still crafts Swiss percs, though he's shifted focus to heady glass rather than production pieces. His innovation lives on in countless designs you'll find at Smoke Cartel and across the glass community.
How Swiss Percs Are Made

Creating a Swiss cheese bong requires different lampworking techniques than cutting traditional percolators with saws or lasers. The function comes from what's removed from the glass, not what's added.
Here's the process: A lampworker blows two plates of glass and fuses them together. Using a torch, they carefully melt holes through both plates, then weld them into the tube structure. Despite appearing delicate, well-crafted Swiss percs use thick glass with expert welds that make them surprisingly durable.
This construction method means each Swiss perc piece has its own character. The position and number of holes affect function, which is why two Swiss perc bongs can deliver noticeably different smoking experiences.
Dialing In Your Water Level
Getting the right water level makes or breaks Swiss perc function. Because these percolators integrate into the tube itself rather than hanging from a downstem, water placement is critical.
Start by filling your piece so water covers about a third of the Swiss perc chamber. Take a test pull. Watch how the water moves. You want full diffusion reaching the top of the Swiss chamber without splashback hitting your mouth.
Not getting full use of the holes? Add a bit more water and try again. Getting splashback? Pour some out and retry. Finding your ideal water level takes a few attempts, but it's worth it. Once dialed in, your piece functions exactly as the glassblower intended; smooth, flavorful, and effortless.
The Swiss Perc Experience
Drag reduction is where Swiss percs really shine. These pieces typically require minimal lung power to clear. That effortless pull comes from the open chamber design and strategic hole placement.
When paired with other percolators like a honeycomb or tree perc, the Swiss perc works downstream to further break up bubbles created by the first filtration stage. This stacking creates a compound effect: smoother, cooler, more flavorful hits with every percolator combination.
The heavy chug you get from a Swiss perc can't be replicated by stem-mounted percolators. That's because the entire tube participates in filtration. Each position and hole pattern delivers a different character to your smoke. Adjust your water level, and you're essentially fine-tuning your smoking experience on the fly.
Pro Tips for Swiss Perc Owners
Keep it clean, keep it smooth: Swiss percs trap resin between those welded holes. Regular cleaning prevents buildup that kills function. Pick up a quality glass cleaner from Smoke Cartel or your local headshop, fill your tube completely, and let it soak overnight. Pour it out, rinse with hot water, and you're back to pristine function.
Water level matters more than you think: Don't set it once and forget it. If you switch between flower and concentrates, adjust accordingly. Concentrates produce less smoke volume, so you might need slightly less water to optimize flavor preservation.
Pair smart: Swiss percs excel when combined with one other percolator type. Stacking three or four different percs sounds cool but often creates too much drag and dilutes flavor. Let your Swiss perc do what it does best, polish the smoke after initial filtration.
Mind the angles: When pulling, keep your piece relatively level. Extreme angles can throw off water distribution and reduce how effectively those holes generate bubbles. A stable, level pull gives you consistent function every time.
Conclusion
The Swiss perc proves that innovation in glass design isn't just about adding more, sometimes it's about strategic removal. These hole percolators deliver exceptional filtration and drag reduction by forcing smoke and water to navigate around welded openings, creating that signature smooth, low-effort pull. Whether you're exploring your first quality piece or adding to a collection, understanding Swiss perc function helps you appreciate the engineering behind the experience.
