Have you ever heard about the fabled secondary explosion?
The fable is based on a true story, and in rare instances, it is caught in slow motion.
Check out this ballistic gelatin’s secondary explosion, all caught on video.
This rare phenomenon, which usually happens only in clear ballistic gelatin, is called a secondary explosion.
A high-velocity bullet is fired from a revolver into clear ballistic gelatin. The impact opens up a temporary wound cavity. Then, as the bullet moves through the gelatin block, it ultimately exits the block and the cavity collapses. Micro explosions can then occur with great force, though usually it takes slow-motion footage to catch such an explosion.
Secondary explosions do happen. This incredible slow motion footage is absolutely breathtaking to witness.
