An 80lb bag of dry Quikrete concrete mix was tested against several high-powered rifle and handgun rounds. While it successfully stopped .44 Magnum, .223, .450 Bushmaster, and .30-06 rounds, it was penetrated by a .50 Caliber round. The concrete bag exploded with most impacts but contained the projectiles, except for the .50 Cal.
This video demonstrates the construction of a DIY 'Christmas Body Armor' using a cookie tin filled with river pebbles and duct tape. The host, from 704 Tactical, conducts ballistic tests against 9mm and 5.56 rounds, showing surprising effectiveness in stopping projectiles. The analysis highlights how loose pebbles fragment bullets and provide a 'self-healing' effect with built-in spall protection, though this is strictly for entertainment and not real-world protection.
