This experiment tests the bullet-stopping capabilities of 250 pounds of Play-Doh against various calibers. Penetration depths ranged from 4 inches for a .22 LR to 24 inches for a .50 BMG, with 9mm penetrating 10 inches and .45 ACP/ .50 AE reaching 22 inches. High-velocity rounds like the .223 AR-15 and 12 gauge slug penetrated 9.5 inches, demonstrating that while Play-Doh offers some resistance, it is not a reliable bullet stop for most common firearm calibers.
This experiment tests Play-Doh's ability to stop a 9mm bullet. Initially, 40 layered Play-Doh disks were easily penetrated by a 9mm FMJ round fired from a Glock 17. Compacting the Play-Doh into a dense block proved more effective, eventually stopping the projectile after reinforcing the setup.
Kentucky Ballistics conducts an interesting experiment testing the density and impact of a .454 Casull round on a large, ten-pound block of Play-Doh. The video details the setup, using thirty containers of Play-Doh molded together, and then showcases the projectile's penetration and fragmentation through the material. The specific firearm used is a Ruger Super Redhawk Alaskan chambered in .454 Casull, with Hornady 300 gr. XTP MAG hollow point ammunition. The results are presented as entertaining and fun.
