Textbooks in Backpack BULLETPROOF? (And A Better Alternative)
This video tests the ballistic resistance of a backpack filled with textbooks (simulated by 1,200 sheets of paper) against various calibers. While paper offered some protection against smaller rounds like .22 LR and .380 Auto, it was ineffective against a 9mm and completely penetrated by a .223 rifle round. The host concludes that passive protection like textbooks is insufficient for school safety, advocating for active deterrents.
