I am looking for footage of the explosive charge of a hand grenade going off without the fragmentation shell. I am interested in seeing what the raw concussive explosive blast looks like WITHOUT the shrapnel generated by the shell of the grenade. This footage is not easy to find, does it even exist? I don't know. I would appreciate any assistance that anybody could offer in uncovering or perhaps even producing such footage, if one happens to have a grenade just lying around that they could take apart

FYI I do not have a background in the military but I am interested in some of the hardware. I am making a website about the weapons in star wars and this is part of my research.
