The short video of Small electronics massively overload on Youtube shows the beautiful scenery of some common electronic components under high voltage and high current.
LED
The beautiful LED flowers and the waning moon fall under the strong pressure, which is sad:

The scene of four LEDs being sacrificed at the same time:

Resistor
Passive device resistors that never provoke trouble are also very angry when they are pressed:

7805
In the digital circuit, the 7805 (three-terminal series analog voltage regulator circuit) belongs to the existence of the old scalper. Under the action of high voltage DC, it collapsed instantly.

VFD
The VFD (Vacuum Florescent Displayer) operates at a driving voltage of 10 to 15V, and emits light by electron bombardment of the phosphide covered on the anode.
The collapse scene under the high pressure of VFD:

flash
The flash can instantly pass a large current and emit a strong and dazzling light. But if it is continuously lit, it will burn.

neon bulb
Neon bulbs are often used to indicate high voltages and require large series resistors to limit current. If there is no current limit, it is easy to burn out.
