If I have a pen with refillable ink, can I just pour in concentrated Hydrochloric acid or concentrated sulphuric acid in the ink chamber to make it an acidic pen?
Would it be better to use the acid of suitable molarity instead of being concentrated?
Then if I write with it on a paper, will it burn?
Is this a good idea to play with?
Is it dangerous in any way?
Is it illegal to make such things for experimenting and fun?
Is there any other safe method to achieve the same?
What are the odds that the poured acid will burn the ink chamber itself and start leaking?
Can it be used in any constructive way? Like cutting many sheets of paper at once. Or using it in industries suitably to make smooth cuts in materials that can be burned with the used acid.
Will it be fun to you?
Thanks to everyone.
I would like to add a few details.
Assume that the acid is not concentrated but of suitable molarity to just cut the paper. I mean, to pierce through it and burning its edges to just make a nice cut. Like a glowing incense stick makes when made to touch a paper. Also, the nip of the pen and the ink chamber are strongly inert; enough to survive the concentrated acid's attack and prevent leaking. Like, the chamber can be made of glass (in which acid's are usually kept) and the nip can be made of galvanized/electroplated iron.
Or if there is still more, we can just make this into a thought experiment.
