Movies Vs Real Explosions | Movie Explosions Are Fake

Published on January 19, 2026
Duration: 2:03

This video from CajunBoyJake breaks down the science behind real explosions versus movie special effects. It explains the critical difference between high explosives (detonation, supersonic) and low explosives (deflagration, subsonic), noting that movies often use low explosives to create visually appealing fireballs. The speaker, demonstrating high authority, also briefly showcases the Olight Osight XR optic.

Quick Summary

Real high explosives detonate at supersonic speeds, creating shockwaves and dust clouds. Movies often simulate explosions using low explosives, which deflagrate at subsonic speeds to produce visually appealing fireballs. This distinction is crucial for understanding the science behind cinematic effects versus actual explosive events.

Frequently Asked Questions

What is the main difference between high and low explosives?

High explosives detonate at supersonic speeds, creating a powerful shockwave and typically a dust cloud. Low explosives deflagrate at subsonic speeds, producing flames and fireballs. Movies often use low explosives to simulate explosions.

How do real explosions differ from movie explosions?

Real high explosive detonations primarily generate dust and shockwaves. Movies commonly use low explosives or pyrotechnics to create visually dramatic fireballs, which are not typical of pure high explosive events.

What is detonation?

Detonation is a rapid, supersonic combustion process characteristic of high explosives. It involves a shockwave propagating through the material, causing near-instantaneous decomposition.

What is deflagration?

Deflagration is a slower, subsonic combustion process associated with low explosives. It burns rapidly, producing heat and expanding gases, often resulting in a visible flame or fireball.
