I started to laugh at his outburst but I could still see him showing concern with his expression.
"Dude! I'm serious here! I have no idea where to start with this improvised bulletproof thing! I'm gonna use the best materials here and just pile it all several inches thick if that's what it takes! It won't go through as long as it's thick enough, right?! Why did I even volunteer?! Shit!" he exclaimed.
"Hah! Come with me then. I'm not too sure either but we have a place we could start with. We already know the materials he used before and we pretty much have everything here to experiment. We'd need to build on his idea first and proceed with trial and error. If we make something really good we could use it for future projects." I replied.
"Shit dude, I thought we'd go into this blind. Hah! Where are we going?" he asked.
"In my room it's better to show you a few videos so you'd have a general idea." I replied.
