You've probably heard the term in a movie or seen a gritty TV drama where a character is trying to survive the isolation of a cell. Honestly, the "fifi" is one of those things that sounds like urban legend until you actually look into the mechanics of correctional facility life. It’s basically the ultimate example of human ingenuity under extreme constraints.
When people ask about how to make a fifi, they aren't usually looking for a DIY craft project for their living room. They’re usually curious about the subculture of "making do." It’s a makeshift artificial pheromone-bridge, a way for people in total isolation to reclaim a sense of physical sensation using nothing but trash and laundry.
The Anatomy of the Most Famous Prison Invention
Let’s get real for a second. In a high-security environment, you don’t have access to much. You have a towel. You might have a glove from the mess hall or a plastic bag. You definitely have some sort of lubricant—maybe hair conditioner or petroleum jelly from the commissary.
That’s the recipe.
The most common method involves a standard-issue bath towel. You fold it lengthwise, usually in thirds, to create a thick, sturdy base. Then, you roll it up tight. Not just loose-roll tight, but "pressure-cooker" tight. This creates the structural integrity. If it’s floppy, it doesn't work. Once it’s rolled, you need a core. This is where the "sleeve" comes in. A latex glove is the gold standard, but since those are hard to find in many facilities, a sturdy plastic bag is often the substitute.
Why the Materials Matter
You can't just use any old plastic. If it’s too thin, it tears. If it’s too crinkly, well, the noise is a bit of a giveaway. Most guys look for something with a bit of "give." They tuck the bag into the center of the towel roll and fold the edges over the top, securing it with rubber bands or even strips of torn bedsheets.
Then comes the lubricant. This is the part that actually makes the device functional. Without it, you’re just looking at a pile of laundry. In places like San Quentin or Pelican Bay, inmates have been known to get creative with whatever the commissary stocks. Vaseline is the prize, but baby oil or even heavy-duty lotion gets the job done.

The Science of Why It Works
It’s about friction and heat.
Humans are wired for touch. When you’re in a six-by-nine-foot box for 23 hours a day, the brain starts to crave sensory input. A fifi isn’t just about the physical act; it’s about the "hack." By pouring warm water into the glove or bag before it’s secured in the towel, the user creates a heat-retention system. The towel acts as insulation.
It stays warm. It feels, for a fleeting moment, like something other than a cold concrete room.
Common Variations and MacGyver Tactics
Not every fifi is built the same way. It really depends on what you can "borrow" from the various departments in the prison.
- The Pringles Can Method: If you have access to a canteen, a cylindrical chip can provides a hard outer shell. You stuff the towel inside the can. This keeps the shape perfectly consistent.
- The "Double Glove": Some people use two gloves with a layer of warm water trapped between them. This creates a "waterbed" effect that is highly prized in the yard.
- The Sock Alternative: If a towel is too bulky to hide during a cell toss, a pair of thick wool socks can be used, though they offer much less resistance.
It’s kinda fascinating how the design hasn't changed in decades. You can find references to these things in literature from the 1970s and they look exactly like the ones being made in 2026.
The Risks You Probably Didn't Think About
Is it "illegal" to make one? In the outside world, obviously not. Inside? It’s considered "contraband by alteration." If a guard finds a towel that’s been rolled up and taped, they’re going to confiscate it. It’s also a massive hygiene nightmare.

In a place where staph infections and MRSA run rampant, a reusable device made of porous fabric and plastic is a literal petri dish. Without the ability to properly sanitize the "sleeve," users risk some pretty horrific infections. This is a detail the movies always skip. They show the ingenuity but never the trip to the infirmary three days later.
Cultural Impact and the "Forbidden" Knowledge
The reason people are so obsessed with how to make a fifi is that it represents the "forbidden" side of human nature. It’s the same reason people watch Orange is the New Black or Prison Break. We want to know how humans survive when everything is taken away.
It’s a symbol of autonomy.
When you make a device like this, you are effectively saying that the system can’t control your body or your sensations. It’s a tiny, weird, slightly gross rebellion. But it's a rebellion nonetheless.
Moving Toward Actionable Understanding
If you’re researching this for a script, a book, or just because you fell down a Wikipedia rabbit hole, there are a few things to keep in mind regarding the reality of prison life and improvised tools.

- Understand the Scarcity: Everything is a trade. A glove might cost two soups (Ramen). A towel is government property. Damage it, and you get a "shot" (a disciplinary report).
- Focus on the Textures: When writing about these things, don't just focus on the "how." Focus on the sounds—the crinkle of the plastic, the damp weight of the towel. That’s where the realism lives.
- Acknowledge the Psychological Toll: The existence of the fifi is proof of the psychological strain of isolation. It’s a coping mechanism, plain and simple.
To truly understand the "prison MacGyver" mindset, you have to look at everything as if it has a second, secret purpose. A toothbrush isn't just for teeth; it’s a handle. A towel isn't just for drying off; it’s structural support. A plastic bag isn't for trash; it’s a vessel. Once you start seeing the world that way, you’ll understand why the fifi is such a legendary piece of convict kit.
It is the peak of turning nothing into something. It’s desperate, it’s clever, and it’s a fundamental part of the hidden history of incarceration.
Next Steps for Research:
If you are looking to delve deeper into the world of prison improvisation, look for memoirs by former inmates like Shane Bauer or Wilbert Rideau. Their accounts provide a factual, non-sensationalized look at how tools are created in environments of extreme deprivation. You might also check out archival footage from the "museum of contraband" collections often maintained by state departments of corrections to see the physical evolution of these devices over the last fifty years.
