What the... these ammo boxes weigh like 5kg. Who goes around throwing them around? Wth?
Also, he caught the box with his hands, even if it was particularly volatile, how'd that cause an explosion? It's really no kind of impact, and ammo, even old ammo, particularly any ammo a military would use, is designed to take quite a beating and still only go off when properly fired. Soldiers won't be handling magazines with silk gloves after all.
Also, this creepy cousin not only installed this expensive AF virtual reality machine in his room, but also apparently carried him in his arms inside the machine?
Still, I'll be bookmarking this.
