how many safety glasses does it take to stop a bullet?
This experiment tests the ballistic resistance of DeWalt safety glasses against various firearm calibers. It was found that two pairs stopped a .22 LR, six pairs stopped a .380 ACP, and seven pairs stopped both 9mm and 5.7x28mm rounds. A .357 Magnum round, however, penetrated twelve pairs of glasses, highlighting significant differences in projectile energy.
