Space knob
Although we have a digital age on the street, and Habr is dedicated to IT, but many more often have to write on paper - so I think that the pen can also be considered a gadget. :)
I think that many people remember the story of how Americans spent a million dollars on a pen for writing in zero gravity. True, few people know that, although the Russians wrote with pencils, after the invention of the pen, they bought a hundred of them from the Americans.
The technology used in the pens is simple - ink is fed under the pressure of compressed gas in the upper part of the rod.

They claim to work at temperatures from -35Âş to + 120Âş, under water, in zero gravity, at any angle.
In fact, in order to join the space technologies, it is not necessary to buy a pen - you can simply buy a rod and stick it into your Parker, for example - the adapter comes in the kit. But I decided to be consistent, and I liked the design of the pens, so I took the space pen. Immediately spend money on a “life-long” pen nibbling on a toad, so I bought it cheaper - the Bullet Space Pen. And the price is small, and I liked the design.
The pen comes in a small case, where, besides the pen, there is a flyer with history and the principle of work.
The photo above is not mine, I have already stuck my case somewhere. He, by the way, was opaque, black.
But everything was decorated well, because, I think, such a pen can be considered as one of the variants of the ideal gift (when it is not clear what to give, but it is necessary to give).
In the “folded” state the handle is small:
In the worker - a convenient length for writing (the cap is removed and put on the back side of the handle, increasing its length):
In terms of use - the usual ballpoint pen, the ball diameter from 0.9 mm (fine) to 1.3 mm (bold). Whoever is used to gel pens, the lines will appear thick (gel is usually 0.5 mm ball diameter).
Under extreme conditions, I didn’t check it - because for a short time a regular pen can work in them, and to sit and write for a few hours at -35 degrees under water in zero gravity - well, it's nafig. :)
A small video clip - a letter through different liquids:
The usual ballpoint pen does not write through the water. Gel writes.
Bonus - works as a capacitive stylus, and not one of the worst in terms of ease of use (as far as it is generally applicable to capacitive stylus :)). But the pen is still metal, because I often do not recommend using it as it is, you can scratch the screen.

An interesting design (when folded often they are interested in “what is it with you?”), Many variants of execution. My version is called "Brushed Chrome".

Their peculiarity is that they do not have a rod, and the capacity for ink is the whole body of the pen. Declare that the ink should be enough for the whole life of the user (or to draw a line 30 miles long), and if not enough - fill / replace for free.
