My mate lives right next to a Aluminum plant and every once in a while they have explosions because the Aluminum powder is explosive. So I was thinking in my head that if this was the apocalypse, that would be a good trap. It made me want to find a way to make a Aluminum cloud from far away. I thought about using a fire extinguisher to push out the cloud and I could hide the extinguisher under a car to remote activate it. The car would act as cover for the enemy but that would be their downfall. The theory is that if I activate the extinguisher, it will make a cloud of Aluminum and with the next shot they use from their guns, It would activate the aluminum in a giant fireball taking them out.
Moral of the story, I have no idea how to make this but if it could be made and was compact, it would be a helpful explosive that could maybe stop a gun fight in it's tracks.
Anyone understand what I mean cause I don't know if I said it to everyone's understanding.
