The .45 goes through a hole made prior. The gummy bear definitely has issues once it starts taking more then a couple shots, but so does ceramic. Using it as a first layer of defense is what I was thinking about, just to diffuse the energy from the bullet if not completely stop it, then use a different sublayer to do the work. Something like making it thick enough to stop pistol rounds and let the other armor do the work. I know this seems like armchair captain territory, but I can't imagine the army considering using gummy bears.
Keep in mind this isn't military grade gummy bears... this is something bought from vet not intended to stop bullets. All I was talking about was the possibility of using something like this. I'm sure weight, thickness could be toned down. Taking into account sublayers or even blending it.
I actually got to these videos from a .22 vs cornstarch video. I don't think this functions the same was as non-newtonian fluids do (cornstarch). Those tighten up when force is applied, this is just more like rubber where it diffuses the energy and grips the bullet (although rubber doesn't do that). Kevlar is similar, but I don't think it's the same thing.
if the weight wasn't an issue, everyone would use steel body armor which can usually stop large caliber rifle rounds.
Once powered exoskeletons become a reality, they can have some pretty hefty armor on them.
Once combat robots become a reality, there won't be humans with body armor anyway, just armored robots.
Yeah then they explode to the kid piloting 00.
