Picture of 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

Picture of 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)

Step 2: Destruction!

Picture of Destruction!
Pic 1: take the bic lighter and the pliers, then push the plier into the hole where the flame comes out, then pull of the metal covering.
It should look like the second picture.

Step 3: The barrel

Picture of the barrel
once again using the pliers, slowly pull the barrel off. there is a flint with a spring under it and the flint will shoot out, so be careful, because the flint is the most important part.

Step 4: The Flash itself

Now the flint and the spring will be revealed.
Strech the spring so its relatively long, then wrap it around the flint.
CAUTION: make sure that the flint is very secure in the spring so that when you pull your arm back to throw it you don't end up setting your pants on fire.

hi there thanks for the info but this one is not so useful as one you shoot out a pellet or one like grenade that you throw but i was thinking of using magnisium lint or similar

That's simple, all right, but it works more like a firecracker. I was looking for something more explosive. Lame in my way, cool in others. Nice firecracker, bro.

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

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?
~Aeronous~ (author)  kevl36 years ago
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.
really? never knew that

 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, 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/

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.
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
GRAVITY BOMBS!!!!!
~Aeronous~ (author)  _Scratch_5 years ago
what?
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.

 oh. I had no idea gravity bombs existed. xD

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

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.

How can I download that video??

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
this is cool and not as dangerous as everybody says
nerfkid4275 years ago
i made one and set my hand on fire
~Aeronous~ (author)  nerfkid4275 years ago
i recommend not holding the burning hot flint in your hand then. only heat it to red hot too, unless your bonkers
thats funny...

Right what? GoCrazy?

You try those links too

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

:-) Peter.
~Aeronous~ (author)  Lateral Thinker6 years ago
:O sry that was my other acount i'm Visper123, that wasn't meant to be related to anything which was spoken about here.
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~ (author)  Lateral Thinker6 years ago
gocrazy is my other account.
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~ (author)  Lateral Thinker6 years ago
no i frgot my password once so i made a different account. gocrazy is my other 1 but i don't use it anymore
Creative thinking. how about a Instructable for that?

:-)
~Aeronous~ (author)  Lateral Thinker6 years ago
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.)

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~ (author)  Lateral Thinker6 years ago
you are in NZ? I might be going there in a few weeks.
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~ (author)  Lateral Thinker6 years ago
you r jokin yeah?
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~ (author)  Lateral Thinker5 years ago
what welcome message?
