You draw on a piece of paper.... if you take electrical technology you'll know that paper isn't a good resister so why would anyone attach high voltage supply to it?
That's why I said it could be a good thing or bad thing. I never said anything about logic or intelligence. I know a battery (dependent on the circuit) can't electrocute you unless it's wired to a power inverter and you short the inverter but there are always certain people who do certain stupid things just because they can.
It would probably shock you but it depends on how much current is going through the circuit so you could use a watch battery and a piece of paper like a switch and power the circuit and it won't shock you or a 1.5 volt battery. if you use something higher than that it might shock you but not that badly just a small shock. If your stupid enough to put that ink on your fingers and stick your fingers into a wall socket you'll die....

First, electrical current never flows instantly, because, you know, relativity.
Second, could anyone give me any useful application of this ?
Schools could learn basic circuits and with 3D printers predicted to become more and more common you could use this to make your own electric devices and give them as gifts or use them for yourself
I have one of these, and it's just a pen. It does exactly what the video says, It doesn't work any different. You just draw a little thing, either a parallel or series circuit and then put out the lights and batteries and it lights up.
I'm writing a whole paper about it for school. And if you draw on your body and then put the battery on it, it barely hurts you, all you feel is like a tiny pinch where you drew.
