Oobleck, A Magical Bullet Stopping Liquid??

This experiment tests the bullet-stopping capabilities of Oobleck, a non-Newtonian fluid, against various calibers. While Oobleck successfully stopped .22 LR and .380 ACP rounds, it was penetrated by .45 ACP and .223 Rem. A .50 BMG round completely destroyed the setup, including the Oobleck container and table, and passed through the mannequin.

This video tests the bulletproof capabilities of Oobleck, a non-Newtonian fluid, against various firearm calibers. While Oobleck successfully stopped .22 LR, .380 ACP, and .223 rounds, it was penetrated by .45 ACP and catastrophically failed against a .50 BMG. The experiment also demonstrated Oobleck's effectiveness against blunt force but its vulnerability to sustained pressure.

This video tests the effect of a .50 BMG round on a non-Newtonian fluid. The high-velocity impact causes the fluid to momentarily solidify, resulting in a dramatic explosion. Analysis shows the extreme energy transfer effectively 'squeezes' moisture from the fluid upon impact.

This video rigorously tests the self-defense capabilities of various airguns against a realistic human head ballistic target. The expert instructor demonstrates that low-power BB guns like the Daisy Red Rider offer minimal threat, while even full-auto CO2 BB guns fail to penetrate the skull. However, a high-velocity Gamo pellet rifle proves capable of causing significant damage, cracking the skull. The instructor concludes that BB guns are unsuitable for self-defense, and while pellet rifles are dangerous, they lack the immediate stopping power of conventional firearms.

This video tests the BulletSafe VP3 Level IIIA vest against various calibers up to .44 Magnum using a realistic human torso dummy. While the vest stopped all tested rounds, including a .44 Magnum and 12-gauge buckshot, significant backface deformation and blunt force trauma were evident, especially with higher-energy rounds. The dummy's shoulder blade was broken by buckshot, and severe bruising was indicated by the .44 Magnum impact.

This review of the Crosman DPMS SBR full-auto BB gun highlights its realistic AR-15 SBR aesthetics and select-fire capability. The host demonstrates its operation, including loading with a speedloader and the dual CO2 power system. Performance metrics like 1400 RPM and 430 FPS are discussed, along with its accuracy and destructive potential on targets like watermelons. The device is recommended for realistic training or plinking where live firearms are impractical.

This video tests the effectiveness and dangers of using a flare gun for self-defense. While a flare gun can ignite materials and cause internal damage to a ballistic torso, its single-shot capacity, slow reload, and high risk of starting fires make it an irresponsible and dangerous choice for defense. The test highlights the unpredictable nature and significant fire hazard associated with using flare guns in a defensive scenario.
