This video is just showing the basic steps and idea on how to refill a Piston Filler fountain pen (a Pelikan M200 used in this demo) the normal way. Which is to dip the nib, and twist the piston knob to retract piston.
I added in an extra step to stop the ink at 80-90% filled, flip the pen, and continue to retract the piston the remain 10%. This is done so to suck the ink out from the feed, so that the feed is not oversaturated with ink, giving a false impression of very wet pen.
