Now what I understand is our human body or a stylus disturbs the electrostatic field of a capacitive screen and thus the mobile calculates the disturbance and does some math and registers a touch.
Now what if I take a thin tube and fill it with some kind of electrolyte (like Vinegar or Salt Water) then put a cotton swab on one end and then use it as a stylus. What will happen...?
Edit: So I tried it with Normal Tap Water. So I had a bit of mixed results sometimes it worked sometimes it didn't. And it did get messy. Now I have to somehow make it efficient.
