You know what they say about us Germans.
We're meticulous and thorough. Right? So, since everyone and their mother have some theories about the Notre Dame fire and how it happened, why not do an experiment.
In comes this mad lad from what I can only assume is Eastern Germany (via his accent), someone who works with wood for a living apparently. And he tries to recreate the incineration of an old wooden beam. It is very enlightening, especially for city slickers like us who know wood only from the TV and have to believe what the news anchor tells us.

If you're too lazy to watch: It's fucking hard to incinerate old wood. He tries out a lot, from gasoline to a fucking flame thrower (!), but he doesn't manage to incinerate the wooden beam. His own thoughts are at the end.
Very recommended watching.
