How the crowd plays it
Ask a room of players this question and the first shout is "Mentos and soda experiment". The ones who fancy themselves sharper go for "Double-slit experiment" — which is precisely why it only scores 15: in Noillirk, feeling obscure is the most common feeling there is.
Real depth starts at "Michelson-Morley experiment" (Deep Cut, 85) — an answer you have to actually know, not just prefer. And at the bottom of the ladder sits "Schiehallion experiment", the designated One in a Noillirk: the single answer the bank's research says a room produces once.
Playing this prompt backwards
When this question surfaces in a dive, your 25 seconds are best spent in reverse: first, name the Plankton answer silently and let it go; second, refuse the Too Clever answer unless the clock is dying; third, search your second page — the runner-up, the older one, the one from the smaller place. In science, that means remembering that work the problem backwards, the way real science often happens: start from the phenomenon and reverse-engineer the name. The mirror rewards reasoning, not just recall.
