There is a similar video, via youtubes recommended related videos, to click on the right hand side.
It seems to originate from the same country.
Most of its comments, are about using the circuit. Very few, actual comment on how dangerous this circuit can be.
The guy in the video below. Is demonstrating that even in the original video (in the first OPs post), apparently dangerous method of using this circuit, can be beaten.
It shows connecting to the mains without using a plug, by jamming in the wires, into the socket (3:53 in video, below)
It has been built in an even more exposed way (fully exposed point to point)
It is just waiting for someone to walk past and accidentally make contact with it
He even demonstrates how to make/mess with it, while it is "LIVE", and touches it for long periods with his hand, while videoing.
tl;dr
Without starting a bad political thread
My understanding is that some countries, have very bad safety precautions in general.
E.g. wires jammed straight into mains sockets, etc etc.
Which is generally NOT seen in the west.
