A few questions to any explosives specialists or people that otherwise have any experience with hand grenades.
- we have had a few incidents where low level gang members have been paid to throw hand grenades into people’s homes, supposedly through closed glass windows. How hard or easy is this? Is a hand grenade heavy enough - or has an appropriately sharp shape or the likes - to break the glass?
- if one was hit by one of these attacks and one miraculously notices the grenade landing on one’s floor, is there anything that could be done to minimize physical damage to one’s body? Would, say, a piece of furniture shield one from the shards?
- are the shards or the blast wave/pressure the more dangerous, or both?

I always wondered about the approach I’ve seen in a couple movies …. Could you save yourself by tackling the bad guy onto the grenade and being on top of him. Aside from the impossibility of being in a situation where that makes sense, and reacting quickly enough, would the bad guy contain both the shards and the pressure enough to save everyone else?
Good question! And if we’re talking movies, I wonder the viability of for instance kicking or throwing the grenade away, assuming there is enough time left.
I don’t remember the movie but I recently saw one where the protagonist reversed his rifle, swung it like a bat, and sent the grenade back to the original thrower. It was good for a laugh
I’m bringing this with me to the shooting club this fall. I hope they let me try it.
Toss it in a water bucket buried at least 4 ft below ground. My guess is that would actually work pretty well.
Not a direct answer to the question, but relevant; they make a film you can put on your windows that holds them together when shattered. This could theoretically cause a grenade to bounce instead of penetrating. Not an expert, do your research before assuming it will work.
If its the stuff I’m thinking of then the grenage will definitely bounce. That film is called huricane film because it’s designed to stop debris hucked by huricane force winds. If someone can pitch a grenade through that stuff then they have a future in MLB.
first, don’t be there, then don’t be detected, then don’t be hit
wall (brick or concrete, not cardboard) between you and grenade should stop fragments, anything less is heavily dependent on what kind of the thing it is and how lucky you are. ikea chair won’t save you, anything solid enough to be worth it would be so heavy that time spent moving it is just better spent moving away. if you live above ground floor, like on third floor or above, it’s likely that you’ll be fine because throwing grenades up is a really bad idea. grenades are round and roughly as heavy as rocks of similar size, perhaps you can get laminated glass windows that should crack but not let grenade through on impact
also don’t forget to hit the floor, feet facing the grenade - even behind cover. This limits the exposed cross section, and puts enough other matter between the grenade and your vital organs to reduce shrapnel lethality.
Other matter being, you know, your feet and legs. Asscheeks if you’re caked up. And a few months of PT is preferable over dying.
No cardboard derivatives?
Only if reinforced with cellotape, of course.
Just put the grenade outside the environment.
that would make the wall unsafe, i’m thinking more about the other ones. it’s not very typical to have cardboard wall, i’d like to make that point
but it’s even better to make sure that grenade doesn’t know where you are
They were making a “the front fell off,” reference.
So was rain_enjoyer. And then they added a missile meme sprinkles in top, if my meme radar isn’t wrong.
They know. Their first paragraph was a good paraphrase of the following line.
You will know for sure that a hand grenade is going to explode right in the next moment when it becomes slightly bigger and you see a few cracks on the outside.
Only if you have really low latency.
“still no cracks, I think we’re good.”
-
easily will break glass, they’re heavy, dense, and hard
-
hit the deck, the explosion will be up and out
-
shrapnel is how fragmentation grenades kill, not the overpressure wave
You are little bit misguided on point 2.

Fragmentation grenades are designed to throw shrapnel in “all” directions. A majority of them will be up from the point of the floor however there are plenty of fragments that will still be thrown laterally across the floor.
That being said you would have a higher chance of survivability laying on the floor behind something.
Hitting the deck is still useful. Standing, your entire height and width is exposed to the source of shrapnel. Laying down, especially feet towards the grenade, reduces this surface greatly.
Obviously some goes out laterally, but next to the ground is where the lowest flux of shrapnel will be.
Sic! Thanks! :)
Although I did think/image that the explosion would go all directions along the floor in 180 degrees.

- Should be as easy as throwing a rock.
2&3. Both pressure and shrapnel are deadly. For pressure, imagine a bubble machine blowing bubbles. You could poke them and they pop. A slight breeze could pop them. This is due to a pressure difference. When an explosive creates a pressure difference, the cells of your body are like the bubbles. They pop. Pressure will have a hard time getting around solid objects. A wall or a chair might be sufficient. Shrapnel will be more difficult. If this is truly a concern, I’d suggest having a “decorative” metal pot. If you could cover the grenade with it, that could potentially nullify its effect. Put as much matter and mass between you and the explosive as possible. If you have nothing available, lay on the ground with your head furthest from the grenade and your feet pointing towards it. Basically you would want to be able to draw a straight line from the grenade through your feet and out your head. Because that’s the direction the shrapnel will take.
Edit: some people in the comments with a fundamental misunderstanding of how weapons work. A grenade is a purpose built weapon that was designed. If you took the explosive out of a grenade, put it in a metal pot with the lid welded on, and detonated, you’d just have a mangled pot. Pots won’t break up into shrapnel it’s gonna look like the T1000 after getting shot with the grenade launcher. And any shrapnel that makes it through, will have its kinetic energy severely reduced.
Downvoted for showing wisdom and speaking truth. Fucking hate social media.

this is just adding more metal to be thrown around
Okay, but what if you had a second larger metal pot to put over the first pot? Like a double paned metal pot, if you will.
Thanks! And, interesting! Wouldn’t the metal bucket/pot do some amplification of the pressure wave on its own by locking it in? Anyway, I imagined having such a pot, but I realized, I cannot know for how long the adversary has been releasing the safety grip and thus how long I have until detonation. It could blow up in my face as I am trying to cover it with the pot. I think I’d go with the second option, to hitting the deck with my head pointing away from the grenade.
While the pot would suffer the brunt of the blast, that’s its purpose in this situation. It also has much more structural integrity than your squishy flesh. If the pot is destroyed, that likely means you are still alive.
A few other thoughts came to mind, something like a weighted blanket or sand bags.
Unfortunately, you’re correct that it would likely be impossible to know how long until it detonates. I don’t have any idea if you can tell that or if possible, how.
Your suggestions aren’t just bad, they’re literally the worst things you can do. Surely you thought about this and found the worst ideas possible, then posted them as a troll. Putting a pot on the grenade puts you in so much more danger. And a weighted blanket?!?!!
“Cover the grenade in more shrapnel” is all you keep saying.
With sufficient reading comprehension you (and the five people upvoting your posting) would have noticed that nobody is claiming a grenade in a pot would be harmless. The claim was about removing the explosive from the grenade and detonating that inside the pot.
While I have no evidence to support that claim I have seen someone putting live ammunition in a pot and making it cook off. That experiment clearly showed that cartridges are only really dangerous when used in a firearm. I expect the physics to be very much the same here.
so your solution to defeating a grenade is to dig explosive out of it?

then your expectations aren’t worth shit, because one is high explosive that does not require confinement to detonate, because reaction zone propagates through supersonic mechanical shock, and the other one is low explosive that has burn rate dependent on pressure, because it burns on surface, which forms foam, which slows down heat transfer, then foam collapses with pressure increase which makes heat transfer faster, but it’s all subsonic. some of the smallest fragments might be stopped by a pot wall, if grenade is in the center, but if it’s close to one wall, then the wall itself would just generate more fragments
but you probably won’t have pot on hand, or realize what is going on in time, and you don’t know how much time is left because of manufacturing tolerances, and you probably don’t have grenade sumps in your living room, so better way would be preventing this situation in the first place, for example using laminated windows or not being a probable mafia target in sweden, if it’s practical. not by trying to cover grenade with a pot, because you just spend more time closer to grenade this way
No, my solution would be to vacate the area post haste. I was just referring to meco03211’s posting in which he wrote
If you took the explosive out of a grenade, put it in a metal pot with the lid welded on, and detonated, you’d just have a mangled pot.
Given your theory that the type of explosive used makes all the difference, I would definitely watch a Mythbusters episode about that (if there was one). 😉
🤣🤣🤣is this how you are in the world too?🤣🤣🤣
go fuck your ignorant self, dude
