Have You Ever Tried to Move Smoke Underwater? Yeah, Me Neither… Until I Did
Okay, picture this.
It’s a Saturday, I’ve had two espressos too many, and I’m knee-deep in a backyard project that started as “just cleaning the pool” and spiraled into me trying to engineer underwater smoke.
Not smoke in water. Not bubbles. Not fog machines. I’m talking real, drifting, moody, cinematic smoke—underwater.
Wild, right?
Yeah, well… sometimes I get ideas that flirt with genius and madness like they’re at a Vegas poker table together. 😅
Let me tell you how this rabbit hole unfolded.
What Even Is Smoke, Anyway? (And Why It Hates Water)
So here’s the science-y part I had to Google with one hand while holding a PVC pipe with the other:
Smoke is essentially a bunch of tiny solid particles (mostly carbon), suspended in gas—usually air. But the moment you try to send that stuff underwater? Bam. Game over. Water’s like, “Not in my house,” and extinguishes any fire before the smoke even gets a chance to puff its little chest.
But I wasn’t after fire underwater. I was after the illusion of smoke. That drifting, mysterious plume that dances and twirls like it’s got its own rhythm section.
I began to wonder if I could build a right handed underwater smoke shifter for beginners.
And then I though, so if fire couldn’t make smoke down there… could something else?
Round One: The Dry Ice Disaster
Let’s just say the garage still smells like failure.
I figured, “Hey, dry ice makes fog, right? Toss a chunk into the pool, and we’ve got instant smoke!”
Well, yes and no.
Dry ice does make fog. But what it actually makes is condensed water vapor that rises off the surface of warm water like a ghost with stage fright. The effect is cool—think spooky Halloween cauldron vibes—but it doesn’t hang under the water. It bursts up and out like it’s running for its life.
So… good for parties. Not great for underwater moodiness.
Back to the drawing board.
Round Two: Smoke Bomb in a Glass Jar (Spoiler: Bad Idea)
I’m not proud of this next part.
I lit a smoke bomb, dropped it into a sealed mason jar, tightened the lid, and let it fill up like a tiny goth snow globe. Then I tried to lower that jar into the pool, slowly unscrewing the lid.
What happened next? A mini mushroom cloud inside the jar… followed by a disappointing glug-glug as pool water rushed in and bullied all the smoke out. It was like watching dreams drown in real-time.
RIP, tiny smoke cloud.
Also, I definitely got a side-eye from my neighbor. Probably deserved.
The Breakthrough: Using Oil to Suspend the Smoke
This is where things got interesting.
I remembered how oil and water don’t mix (thank you, 7th grade science), and a random idea hit me: what if I used mineral oil to trap the smoke, and then submerged that?
So I built a tiny smoke chamber out of a heat-resistant glass container, filled it halfway with mineral oil, and funneled smoke into the top using a hose from a smoke generator (read: modified incense burner + fan).
The smoke stayed in the oil like jellyfish in a lava lamp. It didn’t rise, didn’t escape. It just lingered.
Then—carefully—I placed the entire container underwater.
And guess what? The smoke stayed put. The oil layer held it captive, like a weird chemical snow globe. It wasn’t flowing freely underwater, but it looked like it was. Mysterious, eerie… exactly the effect I wanted.
You ever see something that makes you grin like a madman alone in your backyard?
That was me. Mission: smoked.
The Final Version: How to Move “Smoke” Underwater Like a Pro (or a Lunatic)
Here’s the non-bomb, non-failure version, broken down simply:
-
Get a clear container with a lid – Heat-resistant glass or acrylic.
-
Fill it with mineral oil – Enough to submerge your “smoke” layer.
-
Use a smoke source – Like incense or a small smoke generator, piped in through a silicone hose.
-
Inject the smoke into the container – Let it linger and settle.
-
Seal it off and gently submerge it underwater – Watch your eerie plumes drift like underwater ghosts.
Optional bonus: backlight the container with LEDs and film it in slow motion. Trust me, it looks like a scene out of a dream… or a sci-fi thriller.
Why I Did It (And Why You Should Try Something Equally Weird)
Look, I didn’t set out to be the guy figuring out how to move smoke underwater. I just wanted to spice up a boring weekend and got curious enough to try.
But honestly? That’s the good stuff in life.
Curiosity. Play. Failing spectacularly and laughing at yourself while the neighbor stares like you’ve lost it.
This little science-art-experiment reminded me that magic still exists if you’re willing to get your hands a little dirty and your pool a little smoky.
Or oily. Whatever. You get the point. 😉
Key Takeaways (Because I Guess We’re Adults Now?)
-
You can’t generate smoke underwater directly—it needs to be pre-contained.
-
Dry ice = cool, but not smoke, and it escapes fast.
-
Glass jars + smoke bombs = bad life decisions.
-
Mineral oil suspends smoke beautifully and can be safely submerged.
-
Sometimes the best projects start with the dumbest questions.
If you ever find yourself wondering, “Can I move smoke underwater?”—now you’ve got an answer.
And if you find yourself trying it, shoot me a message. I’ll be in the backyard, refining version 3.0… or just lighting incense and pretending I’m a wizard. 🌀
Either way, the adventure’s worth it.
