space shuttle Aluminum bulletproof?

This YouTube video title, "Papel Higiênico Molhado é à Prova de Bala?" (Is Wet Toilet Paper Bulletproof?), directly poses a question about the ballistic resistance of a common household item. Given the nature of firearms content, this likely involves testing the ability of wet toilet paper to stop or significantly slow down projectiles from firearms, potentially exploring its effectiveness as improvised ballistic protection.

This experiment tests the bullet-stopping power of Lego baseplates against various calibers. A .22 LR was stopped by 27 sheets, a 9mm by 46, and a .44 Magnum by 77. A .223 round from an AR-15 penetrated 88 sheets, while a .50 BMG round went through all 100 sheets, destroying the target dummy.

This video tests the ballistic resistance of Apple MacBook Pro laptops against various calibers. A .22 LR was stopped by the first laptop, while a 9mm penetrated four. The .50 AE stopped at the eighth laptop, and the .500 Magnum at the seventh. A 5.56 round was stopped by the fourth laptop. The powerful .50 BMG Raufoss and API Tracer rounds were both stopped by the ninth laptop, demonstrating significant penetration capabilities.

This video explores whether Oobleck, a non-Newtonian fluid, can act as effective bulletproof material. It aims to answer this question through a scientific demonstration, likely involving projectile testing against the substance. The content appears to be a science experiment focused on material properties and their potential for protection.

This video investigates the ballistic resistance of a Vietnam War-era military helmet. It likely aims to determine how well this historical piece of headgear can withstand modern firearm threats, potentially comparing it to current standards or various calibers. The content is geared towards firearm enthusiasts interested in ballistics, historical military equipment, and protective gear.

This YouTube video, titled "Fivela do Texas é à prova de balas?", translates to "Is the Texas Buckle Bulletproof?". Based on the title and the lack of a description, the video likely investigates whether a Texas-style buckle can withstand bullet impacts or offers ballistic protection. It may involve testing the durability of such an item against firearms, potentially in a self-defense or novelty context. The content's focus on ballistic resistance suggests a possible review or experimental approach to assess its protective capabilities.

This video tests how many cast iron skillets are needed to stop various bullets, from .22 LR to 500 S&W Magnum. Most common handgun rounds like 9mm and .45 ACP are stopped by two skillets. Rifle rounds like 5.56mm and 7.62x39mm also require two to three skillets, while the powerful 500 S&W Magnum penetrates three and is stopped by the fourth. The .22 LR failed to penetrate even the first skillet.

This video tests the penetration capabilities of a .50 BMG rifle, specifically the Serbu BFG-50A, against a section of railroad track. Various .50 caliber rounds, including Raufoss Mk 211 API and silver tip API, were fired. While the rifle and ammunition demonstrated the ability to penetrate even the thickest parts of the rail (over 1.5 inches), bullet deflection and shifting upon impact with the dense steel were observed.

This video demonstrates launching an M67 fragmentation grenade using an X Products Can Cannon towards a distant frozen lake. The Can Cannon, firing .223 blanks, successfully propels the grenade, which detonates upon impact, creating a visible hole in the ice. The experiment highlights the launcher's capability for extreme projectile delivery in challenging outdoor conditions.

This video tests the destructive power of a .50 caliber spotter round against 1.25-inch thick bulletproof glass, comparing it to a standard FMJ round. The spotter round, designed to spark and flash, created a larger crater and more surface damage than the FMJ round, demonstrating its specialized impact characteristics. The Serbu BFG-50A rifle was used for both tests.
