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.

[@ineffable_name]

Its not the capitalistic American way to create something that lasts forever.

[@TubeLVT]

I think that the “forever” part is that one can leave the pen in a drawer or emergency kit for years and it will still work. It’s not that it will write forever, but that one can wait forever to start writing.

You can also wait forever with a regular ink pen. It wouldn't dry out while closed. There's no way for the moisture to escape. And that's with a very cheap pen. Imagine how much better an expensive 30 dollar pen would last. Decades? Centuries?

[@mynyasabut]

@@arsenhere7020 true

[@oM477o]

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

[@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.

[@Tser]

As someone who has done plenty of silverpoint illustration with artist-grade silverpoint pens, they definitely don't last forever and they're not cheap either.

[@jan_harald]

keys would be harder to write with, but sure don't they make actually holdable pens also, though?

In germany, the pencil is called "Bleistift" - translated: "Lead pen", and for a quite some time, those pencils were made with a lead core. They eventually changed to graphite, because people would chew on their pens and lead is a poisonous material, but the name "Lead pen" stuck with the new hraphite pen

[@khaled-b.971]

Same here in arabic countries, pencils are called "qalam rasas (قلم رصاص)" and basically, qalam means pen, and rasas is lead but the material of the pencil core is not lead of course

[@danzjz3923]

​@@shedinjask "lead" in pencils is partially misconception as graphite was called "black lead" upon discovery. There definitely were some pencils that contained lead as it was cheaper, but in modern times there shouldn't really be lead. But even those modern pencils may have had lead until recently! Not in the core of it, but in the paint (which explain chewing concerns actually)

[@mdkhalidurrahman6202]

6:45 A lot of the ink is still left on the ink pipe. the proper way to do this is: to take a paper (like u did) and also a small amount of cotton and measure them out or zero them out on the scale. then push all the ink out with cotton. then measure paper, ink, and ink sock cotton again. this way you will get a much more accurate ink measurement.

[@real-webbe]

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....

[@hurktang]

I know it will shock you, but all metals are metallic. So they all basically reflect light. It will just depend on how much you rub it on and the color of the metal.

[@21scandium42]

The cool thing about this is that it is also probably going to last longer on paper than an ink pen, some inks are naturally acidic and will eat through paper over long periods of time whereas metal oxides are generally basic so they will actually stabilize paper since paper can be naturally acidic also.

[@figboi]

A true forever pen would be when you stop looking at it for one second and the pen is still there on your desk

[@jpostma]

So if it is just a metal alloy, I have a question. Are the drawings conductive? And if yes, can we draw electric circuits on paper? That would be awesome!

[@somemes9546]

Even with a normal pencil you can have a conductive circuit

[@davestorm6718]

The forever-pen can write in any orientation. Also, because it is not easily erasable, I would think it could probably be used for signing documents. Then it would last longer. One main advantage is there is no ink to leak, ruining your shirt, in the hot summer. :-)

[@jonathonhebert7042]

Officially signed documents is a great use case for it! You could probably create a special alloy for yourself and upon further analysis, determine a forgery

[@FoxgirlZoey]

It is also awesome for lefties because of the lack of smearing.

[@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.

[@jonathonhebert7042]

@@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

New idea: instead of wood round the outside, you could use a hollow plastic tube with another smaller one inside. The smaller tube would be hollow and contain some sort of liquid that could stain the paper. It could also have a small metal device on the end made up from an outer shell that holds a small ball bearing that would spin freely when it is dragged against a surface,(such as paper), this contraption would slot on the end of the tube and the liquid Inside the small tube would seep down the inside and coat the ball bearing which, in turn would rotate against the paper and stain it.

[@aniraz90s]

I used a coin when I was younger to scribble on a white paper because I saw that it made line marks. I only did it for fun because I was curious. So this doesn't surprise me at all. 😆

[@insidejazzguitar8112]

This must be why it is called pencil lead, even though it's really graphite. I bet at one time it really was lead.

[@theendicott2838]

It was. In fact, the school I teach at had some pencils with bonded lead in them from a long time ago.

There are metal Carabiners that are used as key-rings, bottle-holder, during paragliding, wall climbing and even camping. If you scratch the carabiners against while wall or even white paper, it will leave a greyish mark. I think the chemical property of forever pen is also the same. BTW during my school days, I wrote everywhere in classroom wall using the metal Carabiner.

[@donaldstrader7241]

Thanks for the video review and also thanks to the commenters which provided some other interesting insights. I once put together an Altoid's box survival kit as part of a contest. Since space is limited, when possible, it is better that any particular item has more than one use. I added some Gremlin Green removable split shot made of tin as part of fishing portion of the kit. This avoided any lead contamination to the kit and I found one could write with them on paper if you needed to leave a note, or record some information.

[@cinfdef]

I think the coolest thing about the foreverpen is that if it's utilizing copper, you might be able to send electricity through it

[@GeoffCostanza]

You can send electricity through anything with enough volts. But any metal, even graphite, will conduct electricity with low voltage.

[@candiman4243]

I've had experiments in school where you can just use regular pencil graphite to make a surprisingly decent wire

[@etalis811]

I wonder if there is a method to create a pen that writes forever by creating dimples on the paper in a precise manner to produce a dark mark without causing significant damage to the paper...

[@GrifoStelle]

Sure. It'll take lateral lighting though. Take a dead pen. Write. Hold the paper so light runs across a side and turn until the shadows is cast down inside the grooves of the letters. Otherwise if we still used clay tablets we could definitely still carve out our writing creating dimples and grooves so that shadow is cast inside the lettering without even having to use lateral illumination. And you could use any tiny bar, tube or stick that you wanted as a pen for ever.

[@dogwalker666]

Called a stylus, The Roman's used them.

[@_just_looking_thank_you]

@@dogwalker666 Mesopotamians were using styli to write in cuneiform thousands of years before Roman civilization; for example, we have Hammurabi’s Code from Babylon. This may even have been a technique used by Neolithic humans. Perhaps making a mark on one thing using another may be one of the earliest behaviors distinguishing humans from the other Great Apes.

[@dogwalker666]

@@_just_looking_thank_you indeed I only gave one example, I was aware they go back a very long time, and were still used in the first schools.

[@kasroa]

Another thing to point out when comparing with the standard biro is that this mini forever pen is only 2.5 cm long and can fit on a keyring, and is very unlikely to fall apart like I imagine an equivalent ball-point would if it were a tiny, plastic 1 inch biro. I still thing it's an overpriced gimick but still, could be handy for some people I guess.

[@jan_harald]

@@marcosolo6491 I'd rather use the keyring, lol, keys tend to be rather sharp also I do have a rather similar size pen, lol, it's a combo of a tiny (like half a finger's length?) phone "stylus" for a keychain, which you can unscrew in half, and one half remains stylus, other half is just a tiiiiny pen ;P best part is, you can always refill it, just get any cheapo pen's core and snip it to short enough ;P

What if the forever is in the name just because the marks written by it can't be erased so they are there "forever"?

[@palerider7171]

The Forever in the Forever Pen probably refers to two things. 1. The “pen” doesn’t dry out like a liquid ink pen so it a available for use “forever” 2. Though looking like pencil, the writing doesn’t fade as quickly ask graphite. So it a permanent or “forever” marking/writing.

[@rootbrian4815]

Ask graphite?

[@Punchy361]

I won't believe this until graphite tells me its opinion on the matter

[@whitemousegary]

Graphite fade "quickly" over time? arr.. graphite has the maximum lightfastness rating, 8. That's hundreds of years you were talking about, dude. Your "quickly" must be in geological scale. If hundreds of years is quickly, don't use paper, it won't last hundreds, try crafting to stone tablets instead. By the way, lead alloy is definitely a bad idea in its fine grained form with your hand intimately touching it for prolonged period.

Can you make circuits with one of these pens by drawing wires?

[@stevewebber707]

It would be interesting to look at the drawn lines under a microscope. My bet is that they would be rather jagged and disconnected on that scale. Which would provide a poor conductivity for a circuit.

[@dogwalker666]

No they are only oxide layers, You could possibly make resistors with it.

[@wheel2man]

You can make a resistor with regular pencil graphite. I remember a simple electric music organ experiment from a book when I was a kid. You filled in a long rectangle of graphite on a piece of paper, taped a wire to one end, and moved another wire around on the area to change the pitch in a simple oscillator circuit. Reminded me of a theramin in sound. I could see a similar effect being caused with these forever pens, but at quite a higher expense.

Your ears are starting to grow

[@chrisgriffith1573]

Paper made using "ground" ... The paper is mixed and pressed with the ground in it's solution before the water is squeezed out. This makes the paper more brittle or stiff, but does make the paper very rough to the touch like fine sandpaper. Talc pumice, chalk, plaster, calsium carbonite all can be used in a medium for grounds, in paper they do the same thing to imbibe porosity into the paper.

[@Dosbomber]

When I was a kid, I didn't have a pencil handy, so I used the soft lead bullet tip of a live hunting round. Wow, did that freak out the 2nd grade teacher. 45 years later, I find out I was doing something that's been used for centuries, known as "metal point" writing. Nice.

[@SolaireIntensifies]

Absolute snake oil sponsor. Why is a science channel pedaling such garbage advertisements? Did you not do an iota of research before taking the cash? Not to mention all the bad science in the video. You were pressing way harder on the forever pen which will obviously use more material. It also looks like you scribbled less with the ink pen. And you didn''t even measure the paper before you added the ink and subtracted the paper. Where's the scientific method? Disappointed in you Action Lab.
