The most menacing part of the experiment is the washer Joerg sharpened at the edges. It’s sort of like a UFO/razor blade combo. The second most menacing part is Joerg joking that he’s going to eat the metal Oreos. “I think I’m going to eat them with a little gasoline to dunk them into.” If anyone would do it, it would be him.
