To make a cheap self-electrocuting device. Sends angry pixies from the power outlet straight to your bare hands, there's no better way for suicide without going through too much trouble. Way better than being burned alive, drowning, suffocation. Maybe jumping from a roof can still beat it, but if you choose the latter, be sure it is high enough to not just make you a heavily disabled person afterwards.
Also make sure it is not too high, or you'll go through hellish seconds overthinking what you've just done (see also:
Instant regrets) before you eventually reach the ground.
