This YouTube video explores the durability of a solid obsidian ball when subjected to gunfire. While the specific firearm and caliber are not mentioned, the title directly indicates a ballistic test or experiment involving a projectile impacting an obsidian object. The video likely aims to demonstrate the material's resistance or fragility under such stress.

This video features a striking visual of a large rock rolling down a mountainous terrain, likely in America given the hashtag. While the title and description are brief, the focus is clearly on the natural phenomenon of the rockfall. No firearms or related topics are mentioned or implied.

This YouTube video features a dramatic test comparing the impact of a .50 BMG round against a 100-pound Kentucky geode. The title implies the geode will act as a bulletproof barrier, creating a visually striking and potentially informative demonstration of the .50 BMG's power and the geode's durability. The content likely focuses on the destructive capabilities of the large caliber round and the surprising resilience of the natural formation.

This YouTube Short features the action of shooting a large diamond crystal. While the video title explicitly mentions shooting, the description is minimal. Without a transcript or further details, the primary focus appears to be on the destructive act performed on the crystal, likely for visual impact and engagement within the platform's short-form content format. The use of a firearm is implied by the term "shooting."

This video tests the durability of a 12-inch solid obsidian ball against various firearms, from .22 LR to .50 BMG. While smaller calibers caused chipping and fracturing, a 12-gauge slug created significant internal damage. The .50 BMG round completely obliterated the ball, highlighting obsidian's brittle nature under extreme ballistic force.

This video provides a review of the National Geographic Hobby Edition Rock Tumbler kit. The content focuses on the features and performance of this specific rock tumbling product, likely aimed at hobbyists interested in geology and rock collecting. The reviewer will assess the kit's components, ease of use, and the results achieved in tumbling rough stones.

This experiment tests the penetration depth of a .50 BMG round into a mountain. Despite using armor-piercing incendiary and tracer rounds fired from a semi-automatic rifle, the bullets only penetrated approximately 12 inches into the rocky soil. The recovered cores suggest that even powerful .50 caliber rounds offer significant cover against mountain terrain.
