About this video

• Video Title: Hand Grenades at 5 MILLION FPS! - Ballistic High-Speed
• Channel: Ballistic High-Speed
• Speakers: Matt Barnett, Bryce
• Duration: 00:34:45

Overview

This video showcases high-speed footage of various explosives, including squibs, blasting caps, det cord, and hand grenades, captured at millions of frames per second. The team uses advanced Schlieren imaging and high-speed cameras to visualize the shock waves and detonation processes, offering a detailed look at the physics behind these powerful events.

Key takeaways

• High-Speed Explosives Analysis: The video demonstrates the use of ultra-high-speed cameras (up to 5 million FPS) to capture and analyze the physics of detonations, revealing details invisible to the naked eye.
• Schlieren Imaging: This technique is employed to visualize shock waves and density changes in the air caused by explosions by manipulating light.
• Explosive Variety: The footage includes detonations of small charges like squibs and blasting caps, as well as larger explosives like det cord and M67 and pineapple grenades.
• Camera Limitations and Solutions: The team discusses the challenges of limited recording time on high-speed cameras and employs strategies like adjusting frame rates and using break wires to capture critical moments.
• Grenade Detonation Comparison: The video contrasts the fragmentation patterns of a modern M67 grenade with a World War II pineapple grenade, highlighting differences in construction and explosive materials.
