The ultimate materials science showdown! When stress hits the yielding point, ductile materials (like our relaxed Tom) just flex and deform without breaking. Meanwhile, brittle materials (poor terrified Jerry) can't handle the pressure and—SNAP!—catastrophic failure with zero warning! The perfect visual representation of why engineers have trust issues with ceramics and glass. No stretching, no warning, just straight from "I'm fine" to "I'm in a thousand pieces on your lab floor."
