You've probably seen it while scrolling through your feed late at night. A close-up of a person—often a young woman—looking directly into the lens, holding a grayish, brittle stick. Then comes the sound. A sharp, distinct crunch that echoes through your speakers. This is the slate pencil eating face video, a subgenre of the internet that sits at the bizarre crossroads of ASMR, nutritional deficiency, and pure viral curiosity. It’s weirdly hypnotic. Some people find the sound soothing, while others are physically repulsed. But beyond the surface level of "why is this on my screen?", there is a complex, often concerning story about why people do this in the first place.
It isn't just about the "crunch."
For many creators, these videos are a way to document a very real medical condition known as pica. This isn't just a "quirk." Pica is a psychological disorder characterized by an appetite for substances that are largely non-nutritive, such as paper, clay, dirt, or in this specific case, slate pencils. While the internet treats it as a niche aesthetic, the reality for the person on the other side of the camera is often a desperate struggle with mineral deficiencies.
What's Really Going on in a Slate Pencil Eating Face Video?
When you watch a slate pencil eating face video, you’re seeing more than just a snack. You’re seeing a sensory experience. Most of these creators focus on the "mouthfeel" and the "earthy" taste. They aren't eating typical graphite pencils used for writing. No. They are eating actual slate—a metamorphic rock—or chalk-based sticks often sold in markets across India and parts of Southeast Asia.
Why the face cam? Because the visual of the jaw working through the hard material adds to the ASMR (Autonomous Sensory Meridian Response) effect. The "face" aspect is crucial for the algorithm. It builds a connection. It makes the act feel personal, almost intimate, which drives engagement through the roof.
The crunch is the star. People describe it as "crisp," "dry," and "satisfying." But honestly, it's a bit of a mask. Beneath that satisfying sound is a body screaming for iron or zinc. Dr. T.R. Murali, a well-known psychiatrist, has noted in various medical forums that pica is frequently a secondary symptom of severe iron-deficiency anemia. When your body lacks iron, your brain starts to misinterpret signals. Suddenly, the smell of rain on dry earth or the texture of a stone seems like the most delicious thing in the world.

The Cultural Context You Might Be Missing
It’s easy to dismiss this as just another "weird TikTok thing." But slate pencil consumption has deep roots in certain cultures. In many parts of rural India, eating bhutdo (clay) or slate pencils is a common, albeit discouraged, habit among pregnant women and young children. It’s often passed down through observation. A child sees their mother doing it and assumes it’s normal.
The digital age just took this localized habit and turned it into a global spectacle. Now, a woman in a village can upload a slate pencil eating face video and get millions of views from people in New York or London who have never even seen a slate pencil in real life. This transition from "cultural habit" to "viral content" is where things get messy. It glamorizes a behavior that can lead to significant health complications, like intestinal blockages or lead poisoning.
Most creators won't tell you about the dental bills.
Slate is hard. Teeth are strong, but they aren't meant to grind stone daily. Frequent eaters often end up with micro-fractures in their enamel. Over time, those teeth wear down until they look like little stubs. It’s painful. It’s expensive. And it's never shown in the "satisfying" 60-second clip.
The Science of the "Earthy" Craving
If you've ever smelled the pavement after a summer rain and felt a weird urge to taste it, you’ve experienced a mild version of what these creators feel. This is called geophagy.

- Iron Deficiency Anemia: This is the big one. When hemoglobin levels drop, the body’s cravings go haywire.
- Sensory Processing: For some, the extreme dryness of the slate provides a grounding sensory input. It’s a stimming behavior, common in neurodivergent individuals.
- OCD and Anxiety: The repetitive nature of chewing can be a coping mechanism for high-stress environments.
Honestly, the "face" part of the video is what makes it so addictive to watch. You see the relief on their face when they finally get that crunch. It’s a dopamine hit. For the viewer, it’s a vicarious thrill. For the creator, it’s a momentary silencing of a relentless craving.
Why Does Google Keep Showing You These?
The algorithm loves high-retention content. Because a slate pencil eating face video is inherently shocking or "cringe-inducing," people tend to watch the whole thing. They comment "Gross!" or "Why are you doing this?" Every one of those comments tells the platform: This is engaging content.
There is also a massive community on platforms like YouTube and Instagram dedicated to "Non-Food ASMR." They swap "sources" for the best slate—white, black, red, or "butter" varieties. They discuss the "grit" and whether the pencil needs to be soaked in water first to soften the "bite." It’s a whole ecosystem built around a medical red flag.
The Dark Side: Lead and Parasites
Let's get real for a second. Slate is a natural product. It’s mined from the earth. That means it isn't regulated like a bag of chips. When someone films a slate pencil eating face video, they are often consuming high levels of heavy metals. Lead, arsenic, and mercury are frequently found in these pencils, especially the cheaper, brightly colored ones.
Then there’s the risk of parasites. If the slate wasn't processed in a sterile environment, it can carry eggs from various soil-borne worms. You're literally inviting a parasitic infection into your gut for the sake of a few thousand views. It’s a high price to pay for "clout."

Common Misconceptions About Slate Eating
- "It helps with calcium": Nope. The calcium in slate isn't bioavailable. Your body can't actually use it.
- "It cleans the teeth": Quite the opposite. It acts like sandpaper, stripping your protective enamel away.
- "It’s just a pregnancy craving": While common in pregnancy, it usually indicates a need for medical intervention, not more slate.
Actionable Steps If You're Hooked (or Curing the Craving)
If you find yourself constantly searching for a slate pencil eating face video, or worse, if you’ve started buying them yourself, you need to step back. The "satisfaction" is a lie your brain is telling you because it’s missing something vital.
Get a Blood Test. Seriously. If you are craving slate, ice, or dirt, ask your doctor for a full iron panel, including ferritin levels. Most people find that once they start an iron supplement, the "need" to eat stones vanishes within weeks.
Switch to "Safe" Alternatives. If it’s the crunch you’re after, try freeze-dried fruits or even ice (though ice is also a pica trigger!). Some people use cornstarch chunks that have been baked, though even that has its own health risks.
Consult a Dentist. If you've been eating these for a while, get your enamel checked. You might need fluoride treatments or bonding to prevent the teeth from shattering.
Understand the Algorithm. Recognize that you are being served these videos because they trigger a "disgust response" or a "curiosity gap." If you want to stop seeing them, start hitting "Not Interested." Don't comment. Don't share. Stop giving the "crunch" the power.
The world of the slate pencil eating face video is a strange one. It’s a mix of ancient habits and modern digital obsession. While the videos might be "satisfying" to some, they represent a real cry for help from the human body. Next time you see that gray stick and hear that sharp crack, remember that what you’re watching isn't just a snack—it’s a symptom. Take care of your health first; the "crunch" isn't worth the cost.
