I've got a great buissiness idea. Instead of having metal at just the tip, you could make it a long thin rod and embed that rod in a wooden tube. Because silver is expensive, you could use a cheaper material such as carbon graphite to save on costs. When the tip gets dull, you could use a device that shaves off some material at the end, forming the tip back into a cone. I call this new invention the forever pen mark 2

[@AmuhAje]

Took me some time before I realized it's just regular pencil, lol.

[@asteroidrules]

Perhaps instead of a wooden tube, we could use a plastic tube. Then instead of shaving down the tube and eventually having to replace it entirely we mount the metal rod inside it such that its position can be adjusted, as it wears down you gradually push the remaining metal out the front so it remains usable. That way when the metal rod wears down entirely you simply insert a new one.

[@vivekyadav]

I was wondering why is it so tiny and difficult to write with. Apparently their selling point is that it fits in a keychain so you can use it whenever you don't have a normal pen. But for $35 pricetag you might as well write with your keys.

[@jan_harald]

keys would be harder to write with, but sure don't they make actually holdable pens also, though? I thought they did? apparently you can just buy specific diameter jewelry wire, and feed it into a mechanical pencil, and use that, lol (diameter depends on the pen, the person I heard from, used 0.5mm or so)

[@msamour]

Nothing says I love you more than giving your significant other a device that reminds them they need to do something about getting old, and not looking as good as before.

[@coconutcore]

I’m a goldsmith, and I noticed this before with silver, so I made a sort of makeshift pencil from leftover silver. Later I learned about silver pens being used throughout history and wasn’t surprised. I’m more surprised we’re NOT doing it anymore really. Edit: I’m just going to add this in here, because I’m getting tired of saying it. People. Silver ISN’T GOLD. The pen in the video is a scam. Silver is expensive compared to most metals, but don’t put it near gold on your scale of value. Don’t come to me with, “lol you know silver’s expensive, right? Idiot.” No shit. I know exactly how expensive it is. Secondly, (and probably clarifying it more) I never said we should replace pens with silver. No one ever used silver in stead of ink for just anything, they had quills. I just think it would be perfectly possible to see people use a silver pen for writing something important or fancy. I use it for signing cards and stuff. For how much silver it uses, when you’ve got more than just a tiny nugget with a screw wasting most of it, you can make something that lasts your whole life in half an hour with $20 worth of silver. It would cost more than the pen in the video at selling price, but that’s not a pen, it’s a pea. Also, just want to point out that the material in the video is “a silver alloy”. This isn’t abnormal, silver and gold are usually used in alloy form, but here it could mean literally anything. Either way, it’s overpriced.

That you mentioned another pen using copper(?) makes me wonder how fast other metals wear down with use. Would be interesting to see a comparison of several metals based on cost and lifespan.

[@jan_harald]

well, its largely just how hard you have to press, and how large the area you draw with, etc kinda like how different grades of pencils work, like a 2B pencil is just way softer than HB, but doesn't mean it AUTOMATICALLY wears down faster, just that at similar pressure, it probably does, as you need way less pressure to make a mark same with the metals, tin, lead, and silver, were historically used *BECAUSE* they were soft enough to draw with, you don't really want to have to push that hard while writing/drawing after all, makes it way harder to do stuff, and tires you out silver was especially favoured as it was less blunting than lead and tin, and as such more accurate (and silver, itself, isn't actually all that expensive, jewelry and such is expensive because of the massive complex labour that goes into making them, both design and production)

[@dvl973]

It's definitely a point of diminishing returns thing. Obviously if it lasts longer it has to leave less material behind, thus it's way more difficult to write with and the marks are way less visible I imagine. Also, I wouldn't advise writing with lead, having traces of lead from writing, all over you and around you on papers can't be very healthy.

[@puchomoreno]

Lead actually works quite well too. The only issue is toxicity.

[@caleb186]

Copper or silver wire and a pin vise/lead holder would be a far more economical way to achieve this same effect. Kind of makes me want to get a lead holder....

[@k.mankeiru8359]

Well for important documents we dont know if the metal can be removed via a chemical that doesnt interact with rest of the paper but does so with the metal, thus opening a way of forging papers. With normal ink its pretty hard to erase that.

@@k.mankeiru8359 The only way to effectively remove the metal traces would be dissolving them. Without using very corrosive acids, I could maybe see this being possible using a method involving the principles of electroplating, but it would be considerably difficult. Ink can easily be removed from paper using solutions of water, alcohol, maybe some hydrogen peroxide or bleach, etc. No matter what you do, it will probably involve liquid of some kind, necessitating ironing out the wet paper to get it flat after being wrinkled from water

I don’t think weighing the weight before and after proves how long the different pens would last, the pen ink is likely much lighter then the forever pen, so the ink pen could use half its total ink and still weigh only a small amount less, whereas the forever pen could use 1/10th and lose the same weight as half the pen ink

Forever likely refers to how long it can be stored for before writing, or likely the fact that, because you can't erase it, your creations with it last "forever" or at least as long as the medium it was created on

I keep one of these tiny pens in my backpacking kit for note taking/writing on my maps if I need to.

I saw an ad for the pen a while ago, and thought the advertising seemed "optimistic". Thanks for doing the test so well, so I don't have to :-)

I think the forever part of the forever pen is the fact that the marking will theoretically stay on the marked surface forever, yk, cuz u can’t erase it off or anything

[@Nancy-hy5so]

They should of mentioned what kind of metal it is rather than an alloy, because some people have metal allergies that might break their hands out when they hold it and also touch where it has come off on paper. I've seen the forever pens on Ali Express but those are erasable. And also color ones. What's crappy is it's hard to find a pack of the color pencil type forever pens they mostly sell them different colors separately or one pen and some different color nibs which seems like a hassle to have to screw off a nib and put a different color one when you want to change a different color. Just buying a pack of color pencils the old way is much better just pull the one out you need and not have to fiddle with the nib each time. On the other hand at least you don't have to sharpen them like regular ones. To me I rather stick with regular ones but I may order one just to see how it does in person and probably throw it away

[@BoyBlunder66]

Okay, but what the hell is that sponsor? Seriously, for a science channel that was some pseudo-science sounding bs, and having it be endorsed by the 'wellness' community definitely doesn't help.

[@sbusna]

Your ears are starting to grow

[@flyingfree333]

That ad was such a scam, really disappointed you would promote pseudo-science garbage.

[@gglovato]

honestly, seeing such a bullshit "homeophatic" shit being shilled on a science channel is cringe-inducing to say the least

[@mrxd7953]

The forever pen is "tin, led and aluminum" the cheapest metals with a secret ratio. A chemical ph strip can be used to measure the exact levels of the metals based on the unit ph trace levels. You can make a true "forever pen" using a "raw iron" nail. A hand forged raw iron nail once sealed in a layer of wax or paraffin will wright for about 20 years at a rate of 100 pages a month. Raw low carbon iron oxidizes at normal atmosphere. Has to be raw forged iron nail thoe, as any tempering or treatment that adds carbon to the iron will result in a nail that will not oxidize "a.k.a rust"

[@victor-xf6hf]

I used to use the metal part of a pencil that holds the eraser to do the same thing

[@cyfralcoot65]

Several years bfore I discovered that you can write with aluminium just like that. I used a small piece of an aluminium power cord from elecricity delivery line (made from almost pure aluminium). And Ive got it from free, since it was just left behind by electricity workers

[@DembaiVT]

The psuedoscience ad? Rediculous.

[@yc1094]

Cool video. You should put a bit through a mass spectrometer and see what metals are in it.

used to do that in class with the rounded parts of paperclips

That must be the most stupid product ever... and I mean the one he was selling.

[@Quartzite]

What if it's called forever pen because when you write with this pen it won't come off, like regular ink would come off in contact with water but it writes under water

[@theproudsoutherner587]

In school my biggest pet peev was writing with a pencil just the texture of it on paper made my skin crawl idk why

[@Breadbored.]

"It's made of special metal that isn't special at all." Ok...

[@darksun4523]

The company would probably say about using the forever pen at an angle and to rotate regularly to maintain the point

[@arnobasson]

There was a kid in my highschool class that used a rifle bullet as his pencil for an entire year. He couldn't erase any of his test answers, but that didn't bother him at all, since he always failed them anyway.

[@kavouskazembakhshi]

Not a good measurement, since the Forever Pen was getting heated which cause it to melt down quicklier while using it continously with that speed.. I believe if you don't use it that way it can take 5 times more..

[@otistically]

Turboflex'll gonna definitely steal that idea.

I used to use the padlock curve bolt? on our school door back at 3rd grade to write on the walls, works like a pencil

[@md_studios9819]

I had a classmate in band class in highschool once who would regularly forget his pencil which we were supposed to bring every day so he would just use his fingernails to make marks in n the paper when we had to note something down

The amount deposited on paper when at the tapered point is not likely the same as when it’s worn down to a more broad tip. Why not just sketch out 17 pages to see if you were right?
