Title text: The creepy fingers that grow from a vibrating cornstarch-water mix can be modeled as a chain of inverted vertical pendulums (DOI:10.1039/c4sm00265b) and are believed to be the fingers of Maxwell's Demon trying to push through into our universe.

I'm imagining Randall trying to actually build something along the lines of the nightmare pendulum, and then deciding it was comic-worthy.

I've seen videos of double inverted pendulums, a small third pendulum on top doesn't seem to be too cursed to me.
