Cat’s Cradle: Chapter 20 Summary & Analysis

Summary
Analysis
Dr. Breed tells John about Dr. Hoenikker’s proposed solution to mud: ice-nine. This is a substance which can make water crystallize at an atomic level. A “seed” of the substance makes atoms “stack and lock” and freeze. Dr. Breed’s explanation is interrupted by the Girl Pool singing “O Little Town of Bethlehem.”
Essentially, ice-nine can make water freeze without it needing to be at a low temperature. The interruption is absurd, the harmless carol contrasting with the potentially world-changing implications of ice-nine.
