XXX Clamped the cell phone in a stainless steel pot, closed with a solid cover of the same stainless steel, called it - no problem, calls. Landed the pot on the water crane - it is still ringing. Greetings from GSM networks

A educated person, understanding the basic laws of physics,
The logical question is "what’s wrong with the pot?".
Marrakech will ask "strangers with physical laws".
That is all the difference.
