How a Grenade Works! 

Next Video: How to Make a Nuclear Reactor at Home

Finally some educational content! Pretty impressive work

Very cool video. As a combat army veteran of the Vietnam Conflict, I have used grenades before. We knew about the timing system after you pulled the pin, but no one ever really explained exactly how it all came together to cause the explosion. The very first thing that surprised me about the hand grenade was how heavy it was.

perfect educational vid, this guy knows how to clearly demonstrate

Seriously one of the coolest videos I’ve come across on here. The other videos that explain this with animations left me with some questions but I really got it with this one. I can’t imagine how long it took to make all these different models, but know it’s appreciated.

This kind of mechanism makes this grenade safer than the German stick grenade. As long as you hold on to the safety lever after pulling the pin, it won't go off.

This video saved my life now I can stop tinkering with real ones trying to figure it out.

So simple yet so genius. Thanks for the video mate

Notching the outside of the grenade body has no effect on fragmentation. Weapon designers learned that long after the fact, and began notching the INSIDE of grenade bodies, or using an inner-notched sleeve or spring. Notched fragmentation works because of the shaped/hollow charge effect, which only occurs if the notching faces the explosive filler.

The way you have explained is simply Phenomenal...

I love the detail you put into showing every part

When I was a kid deactivated hand grenades were readily available with the firing mechanism burned but still complete. They had a spring loaded firing pin that pivoted when the safety handle was released. It struck a primer, much like a centerfire rifle primer. The primer ignited a chemical fuse; no match or hobby shop igniter fuse was involved but the concept is similar.

i love how i saw everything i needed to see at the beginning. that just made me watch yhe entire video respect

That is just incredible! Thank you for the video!

"Ok kids, we're gonna bring a project to class and explain it." *tomorrow* "Ok, who goes first?" Quiet kid: "OH ME ME!" "Come on up" Quiet kid:

Very good quality video on grenades.

Спасибо большое! Очень наглядно и понятно! Браво!

This is one of the best video i have ever seen , short, well made and nice to watch

The most detailed video about hand grenade. Great work

Very cool. Thank you I always wondered how they worked.

This is awesome, thanks man. I can step this up a couple levels.

really cool and visually descriptive way to show how it works, the crafts aspect is also really neat

Just think of all the testing and design experimentation that early engineers must have done before arriving at any grenade design that could reliably work in various conditions. Fascinating

Finally i have seen grenade how works : )

It's impossible not to like and subscribe to such well presented material you work so hard to post. 👍👍

this really amazing ,broken down in the most simple way easy to understand

No words but quite educative than most videos out there

scary stuff, but very instructional, very detailed.

Finally found the video i was looking for, thanks it helped.

Great video. Really amazing cardboard/match grenades. Great Sectioning too!

The best explanation of grenade ever!

Thank you for this..

"Hey" "Look at us" "Who would have thought" "Not me"

Man this is super coollll. Thanks for explaining me how a grenade works with this

Great model making and clear information!

theee best presentation ever!

At the 1:19 mark, the match component was the most surprising part to me. So simple but efficient.

Wow, amazing demonstration of a grenade.

for some reason im becoming supper obsessed with bio warfare and i wanted to now how grenades work, 10/10 understood it quickly and it felt happy and satisfied while watching this video:D

The Best silent explanation on youtube.

Owh~ So that's how you "cook" a grenade.

Thanks bro, now i know how does grenade works

I have always wondered how a grenade works, thank you

Great video ..We had an old one in my Grans house for years,When I was a kid . .All the explosive powder was out of it ..It had a screw cap at the end of it ..

Me: RU-vid's recomendation: Want to see how a grenade works?

Thank you for making my day 😍

Great video often wondered how it worked myself. Found an old hand grenade without the top on it many years ago when I was a child digging in the ground of a neighbor's yard was pretty heavy. Great video nice to see a good one for once

brilliant!!

Nice job

That is a true work of art. Thank you

This will definitely come in handy in my dnd campaign

There is no easier example than this, thank you.

Wow amazing video and very clear didnt expect to find out how a grenade works within few minutes you solved a life long question and earned a sub! Something more : do all grenades work by lighting a match? Or just the old ones? Doesnt using a match rises the possibility of the grenade to fail?

Couldn't ask for a better explanation

This way of working is very easy to understand, thank you very much

It reminds me trailer of far cry 6 when the kid was holding the grenade to the roof after his father pulled the pin.

Now I’m ready for world war 3

Now it makes perfect sense! Thanks!

At first I was curious & finally I found out, thank you for sharing your knowledge 

I was worried when he was just holding the grenade in his hand watching the fuse burn

alternative title: quiet kid arts and crafts

Great demonstration

Well articulated comrade

Thx man I needed this I'm going to Russia tomorrow and I want to fit in with everyone

What makes them explode though? We've only seen fire with the dissection part, is there some sort of gunpowder too to make it explode and not just burn?

That’s amazing you took the time to make all of that

Nice demonstration

Pherb, I know what we are going to do today

I wonder if the people working making these are told “no texting while working”

Amazed by that mechanism

Action and education, love it

7 months recommended to me Then... See you next 7 years.

Really amazing 😯😎

I needed this.

Fun fact! for you people who didn't know, it's actually the spoon you need to worry about on the grenade not the pin my dad was in the Marines for 10 years he taught me about this stuff but I'm not gonna go into detail

Me watching my death feed after eating the funny looking fruit

A man died trying to find that out once

Excellent work, u hv explained in a such a way that an interest person will know exactly how it works. I have decided to downloads a video for future use

Nice work, man.

According to movies... until the PIN drops to the ground in slow motion...it won't explode..😂😂😂

Now i know that a grenade is filled with match sticks... Awesome!

Verygood demo!!!

This video is very useful for all people.

I was today year’s old when I got to know this :O

Ahh , So that's what I was doing wrong all this time , that middle eastern guy sold me duds

Good video. Thanks for your work.

Badass video, I’ve always wanted to know how they worked

How a grenade works That guy :lemme show ya puts it in the head That guy : forgots to put safety Grenade: Boom! Headshot

Никогда не думал что гранаты делают из спичек!)))

this helps me deal with my fear of grenades

5seconds timer I think. Around 3 seconds in the air after throwing it, you'll have around 2 sec to throw it away or run away. Amazing vid.

Problem w granacie na filmiku jest taki, że ten lont w zapalniku który jest odpalany od góry i spala się powowli w dół aż do ładunku jest luźny tzn. jest wsadzony w luźną rurkę i nawet na filmiku widać, że dym i inne produkty spalania są na dole kontrukcji (w materiale wybuchowym, w tym przypadku zapałach) szybciej, niż ogień lontu. Na filmiku granat jest otwarty i nie ma w nim ciśnienia. W zamkniętym granacie jak ten lont zacznie się palić, to przez górną dziurkę, o ile w ogóle taka tam jest, bo chyba nawet nie ma, spaliny nie mają jak uciekać, powodują wzrost ciśnienia i bardzo, bardzo szybko rozgrzane spaliny powędrują do materiału wybuchowego (no normalnie to jest jeszcze materiał inicjujący bo materiał wybuchowy nie koniecznie zdetonuje od samego ognia czy iskier). Iskry, gorący dym podpalą te zapałki dużo szybciej, niż dojdzie tam lont. Można zostawić z 15cm lontu, a wybuch może być już po 3. taki lont w rurce najlepiej zalać klejem na gorąco. Twórcy komercyjnych pterad uszczelaniją to trocinami z gipsem.

Imagine bringing this to an air soft match

You made it easy to understand. Love from India ♥️

Good work! Awesome

That for the tip ;) 🦧

To the FBI agent assigned to me: I swear to everything holy I'm just watching this for research.

are we ignoring the fact that this man made a lethal grenade at home

wow you put so much time into this imitation granade.
