How to make a Flash Bang (Flash grenade)

this instructable will teach you how to make a quick and easy Flash Bang.
this was not my idea, i found it on youtube.
WARNING: while using a Flash Grenade, it is a very good idea to wear non-flammable gloves, and sunglasses.
DISCLAIMER: If you end up hurting yourself or others or setting something on fire, then I take no responsibility for it.

Step 1: Materials

What you need:
Two cigarette lighters, (a small bic one is fine)
the other one is to heat the flint up.
Pliers
Gloves (optional)
Sunglasses (optional)

Comments

[redman88]

only thing i have to say about this is Gloves and Sunglasses are not optional.

To download Go to the last page and click the ''flash video.wmv''

[Needler123]

not sure

[frikkie]

I am gonna try this.But im going to take an empty can,then fit a pull-pin detenator with fuse.Then at the one section a ping pong ball,thats gona make a hot flame,that should ignite the flint.

[dkim10]

How can I download that video??

[SFXguy]

hey dude you know that you can buy bout 20 flint in flint packs to refill zippos
and you can buy springs anywhere.

and also coat the flint in the lighter fuel to give it a quicker heating time

try tossing them on top of coals they heat up, glow, then explode

[MrMadmonkey4]

this is cool and not as dangerous as everybody says

[kevl3]

Hey just wondering if you did hold it in your hand or threw it late would you get burnt. Does it burn at a high temp or does it just burn bright?

[BOXHARD]

 Mg and compounds containing it can easily reach temperatures of over 2,000 - 2,500 degrees F... 

Yeah, it's hot. 

I DO NOT RECOMEND THIS AT ALL. This is very dangerous in that as the Mg deflagralates there is a great potential for extremely hot particles (or sparks) to destroy your eyes... even with glasses, it may manage to fall behind them and it will stick to and burn flesh on contact...

If you are interested in building Flash Bangs, please use a safer alternative where a control distance may be maintained. 

Mg and Potassium Perchlorate for instance makes a terrific flash bang, dangerous? - YES, but it can be initiated from a safe distance.

NEVER IGNITE EXPERIMENTAL EXPLOSIVES / FIRE WORKS / ETC in your hand, under handed toss or not. DON'T DO IT.

Incidently, the mixture I reffered to above is similar to what I was playing with in my profile picture, and that was only a couple grams.

BOXHARD

[Raydoom]

boxhard, how did you get your hands on KClO4 , its the only chemical i cant get in australia ,ive got every dam chemical for adding colour to compositions but i dont have the all important pottassium perchlorate only KNO3 which is useless for colour .... great store for chemicals http://www.americanpyrosupply.com/

[~Aeronous~]

its very hot so you would burn yourself, but the flash is not timed, say you held it on the spring for a while, it would just cool down and go grey, it explodes on impact.

[Needler123]

really? never knew that

[Lateral Thinker]

What is with all these NEW people commenting here? Where's the long term members? What if it explodes? As well as burns bright? Email me when your first instructable is uploaded. (can not subscribe left right and centre) Question, anybody turned out an Instructable on building an Atomic Bomb yet? Anybody working on such an instructable? Even in their dreams? Think about this, the brainier and smarter the people on this planet get, the more ways we find to destroy all life on this planet, and also each idea is faster than yesterdays idea. And the USA Defence Department want such ideas to be cost effective too. Imagine the aliens sitting back, watching us, and laughing their heads off at our stupidity. They got nothing too worry about, we will destroy ourselves, long before we ever become any threat to them.

[uberzombiebob]

If you are so clever then you do it seeing as you appear to think that you know everything even though you quite obviously don't. Atomic bombs are a thing of the past. all you need now is a knowledge of computer programming/hacking, internet access and the correct codes to make all hell break loose by turning your enemies' technology against them. you can even turn missiles back towards their launchers by interfering with guidance systems. in short , we need instructables on how to hack into networks rather than how to build nuclear weapons

[_Scratch_]

GRAVITY BOMBS!!!!!

[~Aeronous~]

what?

[_Scratch_]

Actually, I  was  thinking of a miniature black hole.... =P

--Future of cars is in nuclear power!-- Elec.Nub

[Lateral Thinker]

Visper,

Is that all you can say? Seems you are a man of VERY few words. Just ONE

Gravity Bombs as I know them, come down that fast, they go deep into the ground, and destroy underground bunkers. Like in the last Irga war.

WW2, the British One Ton bomb did the same, they could go through metres of concrete and just one or twocould write off one of the U-boat shelters in France, after months of conventional bombing hard dented them. They were designed by the same guy, who did the spinning bombs used by the DAM Busters.

He was more like an accountant/bomb designer, his bombs were cost effective in resources and lives.

Hey, he was a Aspie too.

Maybe one gravity bomb can go so deep, as to split this planet in half, then we find all the people and countries fighting each other, spilt up opposing sides, give each side their own half planet. The few of us left over, can go off to the moon, and watch the two half planets nuke each other to extinction. Problem solved.

We all lived happily ever after.

Remind me if you done any other project yet?

BTY, just welcoming a new Aspie over on the 10 good traits of a Aspie forum topic.

As for me, I keep falling over, a cop I know saw me, stopped to ask why, it looked like I was drunk, he knew I have never boozed in my life. Anyway, saw a neurologist yesterday, he told me to stand at attention (I could only barely) and shut my eyes.

I went to the right, corrected for that, then he caught me before I hit the ground on my left side.

Ergo, going to get another ride thru the CT scanner soon. My head. Only my feet left to scanned after that.

Try that test on yourself. (just in case, make sure you dont hit something on the way down) My GP or MD, tried every test they knew, none made fall as fast as that. in fact, i did not fall.

Anyway, the CT scanner is only the second most relaxing place for me in the THIS world, the best place for relaxing in THIS whole world is my dentists chair. I am very bad at looking after my teeth, yet the dentist says, I got lost less fillings than most people of my age, and there has been no drilling rig inside my mouth for years

Well, that shows one thing works okay still, my teeth.

Peter.

[~Aeronous~]

 oh. I had no idea gravity bombs existed. xD
Matt

[nerfkid427]

i made one and set my hand on fire

[~Aeronous~]

i recommend not holding the burning hot flint in your hand then. only heat it to red hot too, unless your bonkers

[nerfkid427]

thats funny...

Becuase usage of this instructable can maim people for life, and damage property, and similar ideas have already done so, I for one don't think it is appropriate to have here, few people would be brave enough to tell you that, so thats your answer to,

"How come no ones commenting?"

Despite your warnings and disclaimers, when somebody does get hurt by use of your instructable, you will still be morally responsible if not legally responsible.

Could you live with yourself, knowing somebody has been maimed for life?''

I note this is your first attempt, I suggest you can do a lot better, with a more appropriate topic, and I will watch out for it, in case you deserve a lot nicer comment than this one.

Have a great day.

[owenaero]

hummm the hole idea in this is to teach people the fact remains that anything that is in this site can be used to cause harm it like people saying guns kill people don't be dang fool it not the weapon or the thought it is the person that decides to use it in a harmful way. when you try to condemn a idea you also condemn the whole community in the saying that it causes harm well if people were taught how to use things properly and to also drive in to their heads that they are responsible for their actions and stop using the excuse of (well I read it here so it not my fault) jests use you head I hope you have a better life than to sit on the net looking for people to criticize them for ther work or ideas. if all done this we still be in the dark ages.........

[xACIDITYx]

How could he be morally and legally responsible? The question focuses more-so on the latter. You can go anywhere on the internet for information on how to do any number of things, but the reader makes the decision on whether or not to use the information in a positive or negative way.

It seems to me that there is a difference between informing and "putting the gun in the hand, loading, cocking, and aiming it", so to speak.

Furthermore, if the reader is dumb enough to attempt something dangerous with a disclaimer, then why should Visper feel bad if they maim themselves?

[Lateral Thinker]

it depends on if you have a conscience mate, how would you feel in your own mind?

[xACIDITYx]

But that only would go as far as morally responsible.

[Lateral Thinker]

morally responsible >>>>>>>if not legally<<<<<<<<<

[xACIDITYx]

I'm still a bit lost here, or perhaps you are. How could he considered legally responsible for this? I get the morally, and I don't agree with it, but that's moot as of now. In what way could he possibly be legally responsible?

[Insaneisfun]

He said he wasn't legally responsible but most would find themselves morally guilty if someone was harmed.

[~Aeronous~]

... I'm not in NZ now. i probably wont be till near end of the year

[xACIDITYx]

Actually he said morally, if not legally.

[Lateral Thinker]

Actually my English meant, if he was not HELD legally responsible, he would still in his own mind be morally responsible.

Stop flogging a dead horse Skate, in my mind, Visper has more common sense than you because he understood what I meant first go.

He is from Auz, I am from NZ, and its you jokers whom bombed Japan with the first A-bomb, when Japan were goners already, in affect, your people PLAYED with the biggest most destructive bomb ever, just to see what it could do. All that was needed to end the war, was to blockade Japan until they decided to surrender, no invasion was needed at all.

The USA itself decided it was legal to drop the bomb on civil ins, babies, 5-years olds, 10-year olds, but still a lot of your citizens decided they (The USA) were morally responsible, and more than one nuclear scientist felt so bad about the number of civilians babies and kids killed, that they killed themselves in remorse, holding themselves morally responsibly, if not legally responsible.

[~Aeronous~]

hey, I'm not australian, i just live here. I'm actually from London.

[Lateral Thinker]

No wonder our kids are going into bomb making, YOU are over here. Locally, school teachers no longer want to monitor school yards at lunch times, too dangerous, the government is thinking about calling in the Army, and fitting the only half dozen APC we have, with water cannon. Its going to be the end of the world, as us oldies knew, and loved it. You kids got too much power, but a warning to the wise, wait till you grow up, and you have to deal with YOUR OWN kids. That will teach you.

[~Aeronous~]

Oh and I'm not 15, I am 11, but to have an account you need to be over 14.

[uberzombiebob]

good for you i'm 12 and from gloucester which unless you have a brain you will never have heard of. but since you do have a brain why don't we fight this control freak together.

[~Aeronous~]

Haha, Gloucester in England, I AM from england, and I do have a brain, and that was one year ago, and I am 12, and he has aspergers syndrome, and I made friends with him, and we settled on the argument, and he managed to persuade me to post a christmas tree.

[Lateral Thinker]

I am also the Instructables Robot, you just in effect, pleaded guilty. The process now is that you kindly resign. Its kids like you, trying to sign up for the Army, at the beginning of WW2 by understating your age, that got the world into the mess it is today. Come over to the Aspie forum, we are discussing dust explosions.

[~Aeronous~]

I don't want to be in the army though

[Lateral Thinker]

No way will they have you, if you tell them you enjoy making bombs, the Army is all about peace keeping now. But, the Army just said this morning, if they have to keep the peace in school play grounds, then the Air Force had better reactivate our Skyhawk squadron in case the Army has to withdraw and RUN for their sanity. :-) NZ, due to normal wear and tear, (training crashes) NZ bought up all the Auz Skyhawks when Auz got rid of their one Aircraft carrier Sydney, luckily they were the same model and era. Now NZ is trying to sell them, but the USA has to approve the buyer of '60s technology.

[munkymoose]

Dude, what's your problem? It's just a project and the reader should know that when there's a disclaimer, you could possibly get hurt . Why should the author have moral responsibility? And most people do know what a conscience is. Fewer people, though, have what is called common sense. Common sense is necessary when starting any sort of project, as it alerts you to the obvious dangers of said project.

[Lateral Thinker]

Hey Mate, its an old topic, Visper and me became mates. But it does a pear that you go around looking for ways to make trouble. Over and out

[Capt. Kidd]

not to bring up an old topic, but it's spelled appear, not a pear.

[Lateral Thinker]

Thanks for your help Insaneisfun.

I am beginning to think a lot of people dont know what a "conscience" is.

And just for those who dont know, its that little voice in your head, that tells you that you are partly at least, responsible when bad things happen.

While not naming famous people that dont have a conscience, I will just say that such people are responsible for a lot of pain caused to people on this planet.

One of the milder examples, is the businessman out for a quick profit, who dumps toxic waste on the road side, rather than pay for proper disposal.

True, it is possible he could end up legally responsible (if legal proof was found) but it was his lack of a conscience that caused him to contaminate the environment in the first place.

Visper and myself had a on-going discussion, wide ranging, I found him okay albeit maybe a bit young to understand such things on his own accord, but he fully understands now.

For doubters,

Here is what moral responsibility means.

If you create a small bomb, and publish the plans, with every legal disclaimer you can think of, and a 5-year old kid loses his hand FOR LIFE, its that little voice in your head, named Conscience that will for ever and ever, point your OWN finger at you, and say "You are responsible"

That is the difference between Moral and Legally responsible.

There is one other important difference.

A legal punishment, for such things, is rarely more than a year or two, manslaughter might be 6-7 years, but your conscience will punish you for life, EVEN AFTER you finish your legal punishment.

A conscience can be so punishing, that some people wish that execution was still on the law books, I am thinking of some people imprisoned for life, every day, being reminded why they are no longer free.

[~Aeronous~]

I did warn people though, so if they decide to go and F up their own lives, I don't thnk I would care that much.

[~Aeronous~]

but still, if someone did do that then i would take this instructable offline.

[Lateral Thinker]

Visper, no need to take it off line, but I am sure you will know better in future, its all part and parcel of growing up. Our discussions since, on-list, and off-list, I found you lots more mature that I expected. I guess you were in a hurry to publish something for your first Instructable. Some time ago, in NZ, a 15-year old kid, stole a car, and decided to see how fast it would go. When he finally stopped, the police told him that he had just run over and killed an elderly lady. (it was night) He went into shock, began crying, his whole future disintegrated that second, he had just become a criminal, and no matter how hard he wished, he could not ever turn the clock back to before he got into that car, and decide instead to continue walking. But Visper, I still complement you for having the brains to UNDERSTAND right back at the beginning, unlike some other people whom are continuing to flog the dead horse, after you and me both agreed, the horse was dead, no more more discussion needed and we then both moved on to new and better things. I guess some people got nothing better to do in life than flog dead horses.

[~Aeronous~]

okay... but it WAS actually a school science project, I just chose to put it on instructables

[Lateral Thinker]

Hey Vister, I note your removed your "How come no ones commenting?" of Aug 6, 2009. 1:01 AM which I mentioned in my Aug 6, 2009. 4:16 AM as above. :-)

I suppose I have to be honest, at 15, I was making match stick rockets.

I suppose people grow out of such things, have you got your next project under way yet?

Some years ago, a young kid in Australia, maybe 14-15, spotted a spider in his parents house, and quickly built a flame-thrower to exterminate it. But that was over-kill as he also managed to exterminate his parents half million dollar house.

Oops! (Insurance company refused to pay out)

[~Aeronous~]

lolz, I had a lot of supervision

[Lateral Thinker]

Visper

I would have thought you had better judgement than the teachers at your school. But then, I left school maybe 150-years ago, (That is what it feels like at age 53) and today, I suppose teachers care even less about safety, as long as they themselves don't have to take responsibility.

Would you agree that your school should have steered you towards a safer project?

"Just choosing" to put it on instructables, still does not remove your moral responsibly, how would you feel in yourself if somebody younger than you, with less brains and common sense than you, permanently maimed themselves? (I have worked with such people, burns, can ruin the rest of your life, and some are blinded, or have lost hands, experimenting with such ideas)

Anyway, I am sure you will think twice now.

So what ideas have you got for your next Instructable ?

Look here for some free books, for ideas, its okay to turn some of these projects into Instructables, the books are copyleft (out of copyright), and the rules here allow for use of books like this.
http://www.archive.org/search.php?query=boy%20mechanic%20AND%20mediatype%3Atexts

I learnt heaps from those kinds of books. (BTW, the links are for anybody, not just Visper) and email me if you need some advice. I do not bear grudges.

I just set up a group http://www.instructables.com/group/aspies/ and I will be posting more such links there.

Look after yourself, sorry for my delay in replying, I just had a particularly bad day, was preparing for bed, then I recalled seeing your reply to my comment which was emailed to me, and I had forgotten to reply. I did it ASAP, I did not want you feeling too hurt, and I can see you know better now, so I put you out of your misery by replying this instant.

[Lateral Thinker]

Ps, if you create an instructable from the books on that link, I have interpreted the rules here, as saying you need to credit the source of your idea, so copy and paste the above link into your Instructable. And it is CHEATING if anybody copies and pastes ANY PART of these books into an Instructable, you MUST actually build for yourself the project from the books, and take all your pictures etc, from your OWN project. Otherwise, how will you know what to say about building it, let alone know it works?

[GoCrazy]

Riiiiigghht...

[Lateral Thinker]

Right what? GoCrazy?

You try those links too
http://www.archive.org/search.php?query=boy%20mechanic%20AND%20mediatype%3Atexts

I will be watching for your next instructable (I just subscribed to you)

:-) Peter.

[~Aeronous~]

:O sry that was my other acount i'm Visper123, that wasn't meant to be related to anything which was spoken about here.

[Lateral Thinker]

Will the real Visper stand up please, of cause you are Visper, thats your ID, should not GoCrazy be saying he is Visper?

Whatever, I am going crazy myself with that apparent paradox. . See you later.

[~Aeronous~]

gocrazy is my other account.

[Lateral Thinker]

Multiple personalities then? :-) What next? Should I look up your projects under GoCrazy?

Is there a 3rd personality? Could it be its just you and me on Instructables?

[~Aeronous~]

no i frgot my password once so i made a different account. gocrazy is my other 1 but i don't use it anymore

[Lateral Thinker]

Creative thinking. how about a Instructable for that?

:-)

[~Aeronous~]

for making a eco friendly lighter? (which dont use gas), I need a broken old computer to make it. (sry, no more details, I'm trying to keep it secret so I can get credit.)

[Lateral Thinker]

No way will you ever get credit for something nobody knows about.

But delay too long, somebody will beat you to it, and take the credit.

Seeing you just put the basic idea into the public domain, there are now at least 50 people racing to beat you.

Try this test

http://www.instructables.com/community/test/ is my new forum, I bet if you do it honestly, the picture will have a peak on compulsion, pointing left or right, question is which. My should weight towards the right.

[~Aeronous~]

Damn it, but mine is a certain type which I think it might take a while to figure out

[Lateral Thinker]

http://www.trashpalace.co.nz/

Try where I get stuff from. My friends work there, we call the place affectionately "Trash" but its high up above the city which is at sea level, so gets very cold in winter. The apparent mural to the right of the picture is the truck that collects materials, each household gets 2 per year, but me and friends living near each other share pick ups. People also drop off materials.

About 100 Km north of here, at Palmerston North, their recycling gives everything to local charity shops to on-sell, but apparently, they have a large warehouse just to on-sell recycled computer parts.

So, when will you be arriving in NZ then? PS we are 12 hours ahead of GMT/UTC here, bedtime for me shortly.

[~Aeronous~]

you are in NZ? I might be going there in a few weeks.

[Lateral Thinker]

By now, you will be persona non gratis or whatever, very likely our SIS is already gearing up, and no doubt they got a whole file on you by now. NO Flash Bangs please. (We got enough as our kids have already built thousands since you published your instructable.)

[~Aeronous~]

you r jokin yeah?

[Lateral Thinker]

Anybody with an interest in explosives bears watching. And our kids did not need your instructable to built Flash Bangs, they had a whole industry building them here, before you were even born. Suggest on your profile Orangeboard to delete that welcome message. If in the future you forget what it says, just go find another beginner, that forgot to delete hers, and read that one.

[~Aeronous~]

what welcome message?

[Lateral Thinker]

On your profile, the following has a delete button, mine had, before I deleted it. And I am unable to delete yours for you obviously, BTW, the following I copied from your profile, and pasted here. (sorry for any delay in answering) Jun 2, 2009. 5:44 AMInstructables Robot says: Hello! Welcome to Instructables! I am the Instructables Robot. My job is to alert you whenever someone leaves you a comment or sends you a private message. I spend most of my day sending email. I like sending email. You probably want to upload an image to your profile. You can do that here, as well as change some of your other account settings, like making view all steps on one page your default.

[Lateral Thinker]

Visper, Not sure what the update was, but how about also having 2 fire trucks present, and all the volunteer fire trucks in the area on standby? Have a great day. and hurry up with your next project please, so we can forget this one. Peter Lateral Thinker

[~Aeronous~]

my, next one (or at least the one which I am planning) won't be here until I manage to find a broken computer. it is a cigarette lighter, which is eco friendly. I need to get inspired by something first. Oh and why don't you ever submit instructables? I looked at your profile and you haven't done any?

[Lateral Thinker]

Oh, also your Rescue Helicopter (The USA Medivac helicopter) :-)

[instructors]

I cant imagine this being the safest thing, and it has a low amount of uses, but cool none the less! I think it would be a lot easier is it didn't require a lot of prep time, but if your low on budget and need a good flash this is one of the cheaper flash bangs. Good instructable, informative and relitivly good pictures(hey not every one can have a 10 megapixle 12x zoom camera :) ).

[~Aeronous~]

lolz thanks xD

[~Aeronous~]

oh yeah, but most of the pictures where digitally enhanced.
