I've got a friend that's blind in one eye. Want to guess what he did that blinded him?

Percussion caps and rifle, pistol, or shotgun caps are all too "hard" to use in this application. To get them to blow, you're going to have to hit them with something that's got mass and move that with some force. I do gunsmith work and reloading. A lot of the problems I see are guns with hammers that're not hitting with enough force. You have to have mass striking the primer and mass that forces the primer to stand and be crushed. Mass and mass.

A nail worked for one of you. Where did it go after the explosion?

Wrapping your charge in enough mass that your firing pin meets some resistance is going to put some mass around your charge. Where do you think that mass is going to go when the charge explodes.

Your explosive charge is going to be an unknown to you. If you want to use as little as possible, you're going to have to constrain it. If you constrain it loosely it won't blow at all. If you constrain it "some" it might blow gently and you decide you need more charge. If you constrain it strongly, it might blow strongly. You are not going to develop the right amounts and constraints just by reading a cook book. And you're going to wind up with mass constraining a quantity of explosive. And you're not going to have a clue if it's highly dangerous or just somewhat dangerous. And you're certainly not even considering what might happen if everything didn't go perfectly by plan. What if your bomb happens to fall off the airplane before you planned to drop it? Do you want people stomping around in the fields looking for it? What if it doesn't release at all?
