A simulation of how tattoo guns work has social media users questioning whether or not they’d get a tattoo anymore.

You may’ve been tatted yourself, but the chances are – unless you have a strange obsession with needles – you probably didn’t look too closely at what was really going down when you were getting ink put into your skin.

Thankfully, if your mind has wondered to what actually happens during the process of getting a tattoo, a YouTuber has you covered. If you’re not a fan of needles, you probably shouldn’t read on.

YouTuber Zack D Films took to his platform to share a simulation video of what actually happens when a tattoo gun enters your skin.

The video narrates: “When a tattoo gun enters your skin a needle rapidly punctures the surface creating tiny wounds. This needle moves up and down at high speeds driven by an electric motor and draws ink from a reservoir.”

The video goes on to explain when the tool pierces the skin it injects ink into the middle layer of your skin and with each puncture the ink settles among the cells to form the design.

“This repetitive action builds the tattoo layer by layer, allowing the creation of detailed designs,” it concludes.

Well, you can see it for yourself, but if you thought the description alone was a bit much, the video itself is another matter and it’s not taken long for social media users to weigh in. Warning: Contains graphic imagery:

One YouTube user said: “Suddenly my idea of getting a tattoo on my neck is forgotten.”

“The way he’s just sitting there like nothings happening I’d be screaming,” a second commented, as a third wrote: “Nah bro that speed at the end was faster than my dad getting milk.”

“What happened to those tattoo stickers my elementary school used to have in their prize box,” a fourth added.

And a fifth said: “Is anyone gonna talk about how fast that hand was moving?”

And if you really wanted to get down into the nitty gritty, Florida Tattoo Academy explains there are three main types of tattoo machine – the rotary, coil and pneumatic.

The most popular is the rotary which uses a ‘motor-powered mechanism’ to power needles up and down very quickly’.

The coil on the other hand uses ‘magnets to power the machine’ and pneumatic uses ‘compressed air’.

Well, learn something new every day eh?

A terrifying simulation is unlocking a new fear in people.

Cracking your joints is a satisfying and mainly harmless habit that many people are prone to- however, cracking your neck could lead to very serious consequences.

A terrifying simulation by Zack D. Films has shown exactly what could happen if you crack your neck too forcefully, and it’s quite scary.

Watch below, and read on for a full breakdown of how it works:

What is joint cracking?

First things first, the strange sensation you get in various joints that makes you want to crack them is a result of gas bubbles in the joint fluid.

Harvard Health compares it to ‘blowing up a balloon and then stretching the walls of the balloon outward until it pops’.

What happens if I crack my neck?

As per the simulation below, cracking your neck too forcibly could cause a tear in the lining of a blood vessel.

In rare cases, this tear could lead to a blood clot. Should the clot travel to your brain, it may block blood flow to the vital organ and cause you to have a stroke.

While not all strokes will be fatal, strokes are said to be responsible for 39.5 per 100,000 deaths in the US in 2002, as per US Centers for Disease Control and Prevention (CDC).

In fact, every 40 seconds someone in the country has a stroke, making up more than 795,000 people over the course of a year.

People have since reacted to the terrifying simulation. One person wrote below the YouTube clip: “As someone who cracks their neck a lot, this video feels like a warning of some kind.”

A second said: “New fear unlocked! Thank you again Sir!”

“My neck hurts watching this video,” added someone else.

Away from potentially killing you, frequently cracking your neck can strain or stretch the ligaments in your neck that help to keep your spine in place, explains Neurosurgery One.

It’s strongly advised that you do not use your hands to crack your neck (like the guy in the simulation) and do not crack your neck constantly.

You’ve been warned!

What other body parts do people crack?

One of the most common parts of the body people crack is their knuckles (myself included).

Some have questioned if this can lead to a person developing arthritis, but research has found that there’s little chance that the quirk will have long-lasting damage.”Cracking the knuckles is probably harmless,” says Harvard Health.

“Although there have been occasional reports of dislocations or tendon injuries from overly vigorous knuckle cracking, such problems seem very much to be the exception and not the rule.”

While it may mostly happen in your dreams, falling off a skyscraper does in fact occur in reality too, and you should be prepared in case it happens.

There’s no telling when and where you could fall, but it’s got to happen to someone, right?

If you find yourself teetering on the edge of a mega-high building, you may just thank us for these tips later.

Zackdfilms posted a YouTube Short, detailing everything you should do to survive a fall from a great height, and the tips are widely recommended.

The simulation saw a man (who looked like he was made of clay) falling from a building and following each of the three steps narrated by Zack.

Thanks to doing these things, he was able to live.

Relax (YouTube/@zackdfilms)

When you fall from a skyscraper, relax your body

“First, relax your body by moving your arms and legs to keep them loose.”

Just like the simulation explains, you should relax every part of your body to ensure that you can inflict as little damage to your body as possible.

According to Mayami Oyanagi, a physical therapist who navigated this topic for WikiHow, you need to make sure that you aren’t holding ‘yourself stiff’.

She explained: “Do your best to relax your body so that when you hit the ground your body is more easily able to take the impact. Stay aware of your body, moving your arms and legs to make sure they aren’t locked.”

Break your fall (YouTube/@zackdfilms)

When you fall from a skyscraper, try to break your fall

“Then, aim to land on something that can break your fall, like a tree, instead of the concrete.”

Oyanagi agreed, sharing: “If you’re falling next to a building, or off a cliff in the wilderness, do your best to break your fall into segments by hitting a ledge, a lower cliff, a tree, or another object.”

This will break up ‘the momentum of your fall and divides it into several shorter falls, which gives you a much better chance of surviving’.

Land feet first (YouTube/@zackdfilms)

When you fall from a skyscraper, land feet-first

“If possible, position yourself to land on your feet, to distribute the shock through your legs, but try to roll upon impact to reduce injury.”

It might sound uber painful, but it can save your life.

Make sure to always land feet-first.

The expert and the simulation shared that this was a major step in boosting your survival.

Oyanagi explained: “No matter what height you fall from, you should always try to land on your feet. Landing feet-first concentrates the impact force on a small area, allowing your feet and legs to absorb the worst of the blow.”

She said, that if you are in another position, you need to ‘right yourself before you hit the ground.’

But thankfully, Oyanagi claimed that it’s instinctive to be in this position when we fall.

To do this, you should ‘keep your feet and legs tightly together so that both your feet hit the ground at the same time.’

She added: “Land on the balls of your feet. Point your toes slightly down before impact so that you will land on the balls of your feet. This will allow your lower body to more effectively absorb the impact.”

While there’s no telling what could be below you if you fall, following these steps could just about save your life.

Each week people on the internet are making a revelation about something, and one week in 2025 believe it or not, it’s toe nails of all things.

While it can certainly be easy to forget, it’s extremely important to cut your toenails for general foot health.

But how is the correct way to cut your toe nails?

Those who suffer from ingrown toenails will know how painful it really is, but you may be suffering from them because of the way you cut your toenails.

A video uploaded by Creative Learning, documents how you should cut your nails, and it made clear you should cut your toenail straight.

The clip went on to explain how you shouldn’t cut your toenails too short and also avoid ’rounding the edges’.

A similar video has been uploaded to the ‘Interesting As F***’ Twitter account, with many shocked at how you really should be cutting your toe nails.

“Can confirm the first method causes ingrown toenails and they huuuurt,” one person said.

A second added: ” Cut toenails straight across to prevent ingrown nails. Don’t cut too short, and file sharp edges. Trim after a shower for softer nails. Simple care, fewer problems.”

While a third remarked: “I have definitely been cutting my toenails wrong my whole life lmao.”

Healthline has also done a handy guide on how best to cut your toe nails, and it all begins with the nail clippers.

The website explained: “You should have two nail clippers — one for your fingers and one for your toes. Since your toenails are broader and thicker, they require a larger clipper. Also, by having separate clippers, you reduce the chance of transferring bacteria or fungus between your feet and hands.”

You also need to clean your clippers throughly between each use for obvious hygiene purposes.

Healthline went on to say you should probably cut your toe nails every six-eight weeks, though someone who is more active may have to do it more often.

And speaking of the actual cut itself, the site read: “The fifth step is the actual cut. To avoid painful ingrown toenails, cut your toenails straight across. For many people, this is easiest to do in two cuts — the first one with the clippers slightly off the side of the nail to create a straight edge; the second to remove the rest of the nail following the line of the straight cut.”

You’ll want to finish that off with a bit of nail filling to remove those ‘jagged edges’.
