Efficiency of tennis ball grenade?
i'm preparing for the inevitable day mankind goes primal and I've been messing with tennis ball grenades lately, I've tried "pumping it up" with the addition of black powder and screws. i came to ask if /k/ had any good ways to alter the design of the tennis ball grenade to apply to things such as anti vehicle and anti crowd
>>
>>38526165
Shrapnel?
>>
>>38526173
like i said, i added screws, metal balls, and small pieces of metal.
>>
>>38526165
It's fucking shit. Stick with learning how to make molotov cocktails, tannerite, and simple but stable compounds like ANNM and ANFO unless you want to take chemistry seriously and pursue an education in it (which is overkill for prepping and you should really only do if you're already interested in the field for occupational reasons)
>>
>>38526165
its probably more likely to kill you by accident senpai, stick to guns and avoid confrontation if possible, if it comes to the point you feel like you need a grenade you've already fucked up but you may as well stick to flashbangs or smoke greandes as theyre the only 2 you'll be able to reliably (and safely) make off the shelf.
>>
>>38526351
This.

Im afraid of carrying those things around because of that reason.

>hitting a tree with your bag just a little too hard.
>tripping on something and one of those things landing the wrong way
>something hits them while youre holding or carrying it, also setting it off.

Theyre unstable and unpredictable. Kinda spooky
>>
>>38526165

you should never resort to violence op, if anything happens that you need to prepare for, you definitely shouldn't go out of your way to harm others.
stick to non-lethal methods of survival such as flares and smoke grenades, violence should only be a last resort, and should never be used to kill or maim someone, only as a way to escape.

>>38526165
The container itself being the shrapnel is the best way imo. I'd suggest coating the tennis ball with some kind of metal. Something that has a low melting point. Though I think the ball might catch fire if you cover it in molten metal. Maybe covering it in aluminum foil first?

Second, don't bother with screws and shit like that. Just buy shotgun shells and use the pellets. More effective and they use the space better, so you can fill it with more gunpowder.
>>
>>38526694
Thinking about it you could just use the tennis ball as a mold to make aluminum grenades or something like that. Then just cut away a small part to make a hole, use some scissors and pliers to remove the tennis ball from inside, then fill up even more.

Idk if it'd work but what if you did this:
>M80 or any other firework with enough powder
>4 or 5 cans of flammable hairspray or similar

Make a circle of cans surrounding the m80 duct tape together spray cans with glue sprinkle BBS

Maybe we a chopper broom hand or whatever. Idk how this would turn out though be cool if I loved in the country to test it

Dear anon. You have social anxiety. You have, well a sense of doom. You may even have panic attacks and social phobia. That's not nice. Hugs.
The thing is when you feel axiety (for no reason) you then rush off and look at insane material that makes you think you have a rational reason to feel anxious. When you actually don't.

>>38526165

-Used steel casings for 7.62x39. These are generally more efficient seeing as how they're steel. They're also very cheap and plentiful.
-Black Cat fireworks. You only need to extract the fuses from these.
-Sparklers, yes the little fizzly kinds you play with as a child.
-Birdshot, you can buy this in bulk and it makes a great shrapnel.
-Toilet Paper, a good way to wad it all in, increasing compression and also maintaining fuse position within charge.

Let's break it down Barney style.

Take your sparkler and remove all of the paper. Roll all of the nice blue flash powder out on to a piece of paper with the center folded, pour this into the empty neck of the 7.62x39 cartrige. Repeat this step for your buckshot. don't add too much.
Now, place your black cat fuse into the charge, make sure it's going to contact powder, this isn't a precise science though.
Take enough toilet paper to plug your damn nostrils with and shove it down around the fuse, compressing the shot and flash powder.
Take a pair of sturdy pliers and carefully crimp the neck of the cartridge down around the fuse, not cutting the fuse, but allowing the charge to compress behind your crimp fold and subsequently exploding on ignition.

I don't need to tell you that black cat fuses are incredibly volatile and unpredictable. These little things are comparable to a quarter of a hand grenade and should not be played around with. The concussion in an enclosed space alone would be enough to kill you. Be safe and have fun, /k/.
>>
>>38536993
Wrong. This will make an incredibly inefficient compound. 75% saltpeter 15% charcoal 10% sulfur (by weight)

Yeah you go ahead with the annoyingly painful experiment, and I'll outfit a ton of people with a ton of these things. Fatalities are an inevitability, acciracy by volume.

T. I've found that their failure rate is around one in ten. When crimped and loaded properly, they will produce good effect on target. It's the perfect insurgent hand grenade. Easy to produce, cheap as fuck and has an overwhelming explosion. Try one. It's violent as fuck.
>>
>>38542528
it is dangerous. See those matches in Ops pic? That's an Armstrong mixture which is essentially the same mix they use in ammo primers but not shielded by metal so any friction will cause them to ignite.

I've made explosive arrows with the powder available in sparklers as well. They are amazing things.

Dude an M80 is a "violent explosion". Doesn't mean it's gonna kill somebody.

>>38546057
Yeah, I agree. That is a stupid friction/impact system that is both difficult and dangerous to carry efficiently. See my bullet case sparkler bombs for a much safer, possibly more lethal alternative. I have tested these extensively in many formats.

>>38537062

You're joking right? Those things have almost no explosive power, its just a fireball when they go off.
