can STYROFOAM stop a bullet?

This video demonstrates bullet penetration through a simulated tile floor and a hardwood floor. The instructor tests various calibers and ammunition types, including .380 ACP, 9mm, .40 S&W, .38 Special, .357 Magnum, .32 ACP, 12 gauge buckshot, 7.62x39mm, and 5.56x45mm. Contrary to expectations, the tile floor, constructed with drywall, joist, subfloor, thin-set, concrete backer board, and tile, showed similar penetration resistance to the hardwood floor. The instructor concludes that standard flooring materials are not bulletproof and recommends ballistic steel or fabric for actual bullet resistance.

This video features Edwin Sarkissian, an experienced firearms instructor, conducting a unique bullet penetration test. He uses 12 Ozark Trail 12-inch cast iron skillets to determine how many rounds from various calibers and firearms, including 9mm, .45 ACP, 500 S&W Magnum, 7.62x39mm, 5.56mm, 5.7x28mm, and 12 Gauge slugs, can penetrate the cookware. The results offer practical insights into the ballistic performance of different ammunition types against a common household item.

This video from Edwin Sarkissian provides an expert-level demonstration of the Serbu BFG-50A rifle's capability against a railroad track. Sarkissian, a high-level firearms enthusiast, showcases the .50 BMG caliber's power with various ammunition types, including the specialized Raufoss Mk 211 Mod 0, highlighting its penetration through thick steel. The content offers valuable insights into terminal ballistics and the performance of heavy caliber rounds.

This video demonstrates a unique application of the X Products Can Cannon, a gas-operated launcher compatible with AR-15/M16 lowers, to launch an M67-style fragmentation grenade using .223 Blanks. Expert experimentalist Edwin Sarkissian showcases the process of loading and firing the device towards a frozen lake, highlighting the launcher's ability to hold the grenade's spoon in place until firing. The demonstration results in a significant explosion and ice shatter upon impact.

This guide details a ballistic test comparing a .50 Cal Spotter round against a 1.25-inch thick bulletproof glass panel using a Serbu BFG-50A rifle. The test, conducted by firearms enthusiast Edwin Sarkissian, demonstrates the significant destructive potential of specialized .50 BMG ammunition, highlighting differences in impact effects between incendiary spotter rounds and standard FMJ rounds. The expert-level demonstration emphasizes the importance of understanding ammunition types and their performance against protective materials.
