I think this is right.
The way she places them rules out pins, the handling on the tear down rules out pingpongballonnose style rubber cement (or other tacky adhesives) and breaking the eggs at the end suggests a need for the work to be easy to put in. So flat spots seem most likely.
As I'm fond of saying with this type of trick, the gimmick makes it possible, it doesn't make it easy.
I'm more interested in the glass on fan bit she opens with. I can think of several methods so I want to know which one she's using :)
