From Habr:
xxx: I absolutely do not know physics, but as a child, not thinking about luck, charged condensers the size of a flashbox in the socket. And they swallowed into the rosette, there they moved to crack. Then they picked up and locked up something. is hidden. Was it deadly?

Yyy: Excuse me, if you list on your fingers everything that most of the people here did during their school years, I think there will be so much potentially life-threatening that the very fact of survival and adulthood will be seen as a miracle.
Condors in sockets, bombs of bolts and sulfur, carbide bombs, powder charges, magnesium charges, thermal mixtures, self-shoots of all kinds - what is not dangerous?
