Okay, so today I decided to mess around with this “mouth to lung tank” thing. I saw some stuff online and thought, “Why not give it a shot?”
First, I gathered all the junk I needed. This was mostly stuff I had lying around:

- An empty plastic bottle – I used a 2-liter soda bottle, washed it out real good.
- Some tubing – I had some old aquarium tubing that seemed about the right size.
- A mouthpiece – I actually used the top part of a smaller water bottle for this.
- Tape – Lots and lots of duct tape. Because, you know, duct tape fixes everything.
Then came the assembly. Honestly, it was a bit of trial and error. I started by poking a hole in the bottle cap for the tubing. I pushed the tubing through, making sure it was a snug fit. I might have used a little glue here, just to be sure, but mostly, It is snug.
Next, I attached the mouthpiece (the smaller bottle top) to the other end of the tubing. More tape! I wanted to make sure it was airtight, or at least as airtight as I could get it with, you see, tape.
The big bottle, I filled the bottle with some water. Not all the way, just enough to cover the end of the tubing that’s inside the bottle.
Time for a test run! I put my mouth on the mouthpiece and tried to, well, breathe through it. It was weird, for sure. I could feel the air bubbling through the water, and it definitely felt different than just breathing normally.
I keep doing it several times, It works, I could feel the air bubbling through the water.
Honestly, the whole thing felt a little goofy. It wasn’t exactly a scientific experiment, more like a “what happens if I do this?” kind of thing. Did it do anything amazing? Not really. But it was a fun little project, and it kept me busy for an afternoon. Maybe I’ll try tweaking it later, see if I can make it… better? I don’t even know what “better” would mean in this case, but hey, that’s half the fun, right?
