This video tests the ability of 2-liter soda bottles filled with liquid to stop a 9mm projectile. Multiple bottles were stacked and shot to determine penetration depth. The experiment demonstrates that even multiple layers of liquid-filled containers are insufficient to reliably stop a 9mm round, with the projectile penetrating five layers and only deforming the sixth.

This video explores whether a knife can penetrate Oobleck, a non-Newtonian fluid. The experiment likely involves testing the cutting or stabbing capabilities of a knife against this unique substance, which exhibits properties of both liquids and solids. The title suggests a direct test of the knife's performance in this unusual medium.

This video from Civilian Tactical features an enthusiastic firearms content creator demonstrating the ballistic effects of a .50 BMG round on a gallon of Elmer's School Glue, captured in slow motion. The experiment highlights the projectile's impact and the unique fluid dynamics of the glue upon being struck. The host, wearing an Armored Republic plate carrier, uses a Noreen Firearms Raptor 50 for the test, showcasing safe handling of high-caliber firearms.

This guide details a methodical ballistic gel test for Underwood Extreme Defender .380 ACP ammunition, as demonstrated by Buckeye Ballistics. It covers gel preparation, calibration, barrier setup, and data collection using a chronograph. The test evaluates both standard and +P pressure rounds, focusing on penetration depth, wound cavity creation, and projectile integrity, aiming to meet FBI standards. The expert-level instruction emphasizes objective, data-driven conclusions.

This segment from Gun Talk Radio features Daniel Cox, VP of Product Portfolio at Norma/RUAG, discussing Norma's expanded presence and new ammunition lines in the US market. Cox highlights Norma's commitment to quality control across all manufacturing stages, from brass and powder to primers and bullets. He introduces two new self-defense handgun rounds: the MHP (Monolithic Hollow Point), which is cold-formed to pre-imprint expansion properties, and the NXD (Non-Expanding Defensive), which utilizes fluid dynamics for energy transfer without expansion, offering consistent performance and reduced recoil.

This video from InRangeTV covers Polycase Ammunition, specifically their ARX and RNP lines, showcased at SHOT Show 2017. Experts Ian McCollum and Karl Kasarda analyze the unique fluid dynamics-based design of the ARX projectile and discuss its performance in various calibers, including 9mm and 45 Colt. They also touch upon barrier penetration, pricing, and potential applications for different shooting disciplines.
