A 1959 NFB doc about blowing up a rock doesn't sound subversive until you realize it's basically structural cinema masquerading as industrial footage—three years of tedium compressed into seven minutes of pure anticipation, which is either genius or a test of patience I'm not sure I passed.
Ripple Rock exemplifies the NFB's documentary tradition at its most formally disciplined: a three-year engineering saga distilled through measured pacing and cumulative tension, where the editing itself becomes the architecture of suspense, each cut a deliberate step toward controlled chaos.
The decision to withhold the actual detonation until the final moments—letting the buildup of preparation, tunneling footage, and technical precision carry the weight—transforms what could've been spectacle into something genuinely earned and devastating.
