|Chapter Charging pin
The charging pin is a part of the flux capacitor. It is scenery. The description is "There's a small metal pin on top of [the flux capacitor] with a picture of a lightning bolt next to it."
Understand "small" and "metal" and "top" and "lightning" and "bolt" as the charging pin.
Instead of touching the charging pin with the electrical wire when the light bulb is not part of the electrical wire:
if the flux capacitor is unpowered:
say "Sparks fly to the air when you touch the socket on [the flux capacitor] with the exposed wire. There's a loud click from inside the machinery and the tubes behind the front window light up and start blinking like christmas lights.
The needle on the power dial turns to point at 1.21 gigawatts.";
now the flux capacitor is powered;
otherwise if the flux capacitor is powered:
say "Touching the socket with the exposed wire causes the tubes to brighten for a moment and the needle of the power dial to go to the far end, but it returns right back to the 1.21 gigawatts mark.";
say "There's no effect at all. It's just scrap metal now."
Instead of tying the electrical wire to the charging pin:
try touching the charging pin with the electrical wire.
