How to Make a Smoke Grenade

Editor’s Note: This article is an update of the original – posted one year ago.

Using a Smoke Grenade

These smoke grenades are used by the Military for creation of smoke screens in case of a retreat or flanking maneuvers in order to provide a wall of visual distraction that reduces the accuracy of enemy fire or to signal a position for air supported attacks (or SOS signaling).

Color Meaning:

Each unit designates the meaning and purpose for each color (white tends to be used to mask movement/confuse enemy, etc. only). Sometimes each mission may dictate different color signals for different meanings (lift & shift fire, phase line reached, extract, etc.). In other situations, different colors are meant to mark positions to aircraft to verify that the force on the ground popping smoke is who they say they are.

In peacetime red typically meant that there is an injury and all training is to be halted until the injury is addressed. ( Source )

How to Make a Real Smoke Grenade – the one hour method

One of the best methods to create a smoke grenade is basically a mixture of potassium nitrate and sugar. The former ingredient is also known as saltpeter and usually it’s not available for purchase. But you may use Spectracide Stump Remover which consists mostly of saltpeter. It works just fine!

You’ll need:

The mix will be placed in a soda can that you have to cut in half. In order to create a good mix for this smoke grenade, add two parts of sugar to three parts of saltpeter. Cook these two ingredients and mix them constantly until they create a golden paste that is rather gooey. Stop the fire now as if you keep the mix on fire any longer, you risk igniting it and you don’t want a smoke grenade in your kitchen.

While the mix is still warm and malleable, pour it into the soda can that you cut earlier. You will have half of a soda can filled with a gooey substance that will soon solidify. This is the moment when you need to put a fuse into the mix. Place a thick string about an inch inside the mix and leave at least two inches outside. Then, you can either refrigerate or freeze the soda can or wait for it to cool down and harden naturally. It will take about 20 minutes for the mixture to be solid and then, you will be able to light it on fire.

However: this is a much more powerful smoke grenade than the next one and you should ignite it only in open environments. Also, try to avoid lighting it near your neighbor’s house as he or she might not be eager to be surrounded by a thick layer of smoke. This smoke grenade is unlikely to put something on fire, because it is contained in a soda can, but you should not leave it unattended, either.

How to upgrade your smoke grenade?

1. Add a pull ring fuse:

2. Add more colors: if you want to upgrade your smoke grenade you can also add more colors. This is not something that can be done with the second type of smoke bomb, as you cannot add color into that solid mix of elements. In order to do this, you can simply use organic food color. Note that you’ll have the best (coloring) results using other formulas (point 3):

3. Use other recipes: some chemicals may not be readily available unless you have access to a chemistry lab, but it’s worth knowing how it’s done. The ingredients are sifted together and ignited to produce the smoke.

Here are a few efficient and unconventional fast-tips about protecting your home in time of war or social chaos from a well-known army officer vet Steve Walker.

How to Make a Smoke Bomb – the 10 minutes method (to entertain your kids)

These smoke grenades, also known as smoke bombs, are probably something you did as a child. If not, at least you had a friend who did them.

Depending on the size of the smoke bomb, you might want to add any amount of ping pong balls you want.

This is all you need

However, a medium sized smoke grenade is perfect with about 5 balls. Cut all the ping pong balls. This will take you about 10 minutes. Each piece of the ball should have about half-inch in order to be packed with ease into the tinfoil later. Large shards will not burn properly and they might also puncture the tinfoil too. The alternative is to smash the balls and then rip them apart by hand, but this is much more tedious and you could also get a cut, as plastic can also be quite sharp.

Now you can either place them in another ping pong ball that was previously pierced in order for the shards to be placed inside, or you can directly wrap all of the small bits into tinfoil. If you want a single exit point for the smoke, use a pencil as you wrap the shards. Place it in the tinfoil and wrap the foil around it. Then, take the pencil out and you will have a miniature chimney from which the smoke will come out. The final step that you need to perform during this process is to light up the smoke grenade. Light the part with the ping pong ball shards until you see smoke coming out of the “chimney” and then step back.

How to make a grenade

grenades will have to have one texture when its pinned and unpinned.
And to make it the easiest way we’ll need to create a spritemap. Spritemaps are used to have multiple frames or pictures in one image.

To begin we will create a template for the frames we’ll need.
an easy way of doing this is drawing a line in the centre.
now that we got the template done we’ll start to draw it.
(sorry for the simple design im not very good at drawing)
when you’re done with that you can remove the line and push them together in as small size as possible.
the left one is frame 0 (pin) and the right one is frame 1 (no pin).

Now that were done with the texture we can start coding, but first we’ll need to create the grenade class.

now add the following code to turn it into a grenade.

This is where we start to do some of our own customisation, to start off we’ll make it appear in the editor list.
To do so we’ll just add a Attribute to our class called editorgroup.
just place the code «[editorgroup(«MyMod»)]»

When thats done you’ll add your name and texture.
The spriteMap is a extension of the normal sprite that will cut your image into smaller pieces and then you can select what part you want to show (frame).

the 8,8 is the height and width of each frame and in this case its in a 7 by 7 (fixed it in the next picture).

the _timer is the amout of frames it takes before it explodes (def: 1.2)

Now we can start up duckgame, but when you try to place your item you’ll notice that its not placed correctly in the editor

This will look really bad when you throw it as it spins around the center.
But to fix this all we need to to is add a center value.

the center value is supposed to placed in the center of the collisionbox for it to rotate nicely.
i recommend making it half the collisionsize.

as you can see the grenade is centered in the collisionbox.

Now to change the sprite we need to find some way to check if the grenade has been activated yet,
luckely theres already a value for it. its the bool _pin.
First of all we need to create the update function just like this:
public override void Update()<
base.Update();>
the Update function is called every frame the grenade is in a level.

And now we have to change our sprites frame to 1 if the pin is gone.
This can be done in multiple ways, one is testing if the pin is false and then changing
if(!_pin)<
sprite.frame = 1;>

Your update function should look something like this now:

if you test it out now it should change color.

Now were going to make the grenade somthing more than a regular grenade, we’ll make it explode when it hits a duck.

To do so we’re going to use the OnSoftImpact() function and then check if it hits a duck.

first we need to add the function, its an override just like the Update function and it should looke something like this:
public override void OnSoftImpact(MaterialThing with, ImpactedFrom from)
<
base.OnSoftImpact(with, from);
>
as you can see theres 2 variables in this the MaterialThing with (the object it hits) and ImpactedFrom from (what side it hit the object on).
first we’ll check if the grenade doesnt have a pin with this if statement:

then we need to check if the thing it hit is a duck, this can be done using the as operator that converts it into another type and then we can check if its null.

now all we have to do is set the _timer value to 0.

now your onsoftImpact should look like this:

You should increase the origional _timer value in the begining now so that it takes longer time for it to explode on its own.

Another useful function is OnRemoved() <> which is called when the grenade gets removed from the level or when it explodes.

[EditorGroup(«myMod»)]
class tutorialGrenade : Grenade
<
public SpriteMap sprite;
public tutorialGrenade(float x,float y) : base(x,y)
<
sprite = new SpriteMap(GetPath(«grenade»),7,7);

How to Make a Match Grenade

Introduction: How to Make a Match Grenade

Please don’t judge this Instructable harshly, for this is my first Instructable.

This match grenade is a like a ground impact grenade. When you throw it at a wall or up into the air, it will blow up. This Instructable takes about 10 min. to make. I’m not responsible for any damage it does to you.

(Sorry about the blurry pics)

Warning:

This is dangerous if you aren’t careful. This CAN blow your face off or start a fire if you don’t use it right.

Please be careful. Thank you!

Step 1: Materials

Electrical Tape
About 6 match books (use more for a bigger one)

Careful Hands
Scissors
Gloves (optional)
Safety Glasses

Step 2: Removing

Put on your safety glasses just to be safe. Take the match books off of the matches without ripping the match book. Do NOT dispose of the matchbooks OR the matches. You will be needing them.

Step 3: Cut Match Heads

Cut the match heads off. Try not to have the cardboard on match heads when you cut it. Dispose of the cardboard from the match heads.

Step 4: Cutting Slips

Cut the slips from the matchbooks. Keeping the slips as straight and as big as possible, try to keep the match book colors out of the slips. (The slips are the igniter on the back of the matchbooks). Once slips are cut, dispose match books.

Step 5: Taping It Together

Cut electrical tape at a length of about 3-4 inches. Then cut another piece of tape at the same length. Place the pieces on top of each other on the long side. One should be about one forth of the way to the other end. (See in pictures). Lay slips side by side on the tape. Try to have no gaps in between the slips. Turn the tape over and cut excess slip. Keep excess slip.

Step 6: Rolling It Up

Roll up the tape and wrap excess tape on the tape to where it make a hexagon shaped opening on both ends. Cut a 3 inch piece of tape and place 2 or 3 excess slips you saved in the middle of the tape. Then put it around one end of the hexagon tightly.

Step 7: Filling It Up (Dangerous Part)

Fill up the hexagon and set it down. Put on your gloves. Take a few more match heads and push it in slowly and carefully. Then take more until you can’t do that anymore. Drop a few match heads on top of the hexagon and set it down. Take 2-3 more excess slip and take a 3 in. tape. Put the slips on the middle and tightly wrap the tape on the open end of the hexagon. This is where you start to wrap as tightly as you can with the tape and seal any holes as tight as possible. Using too much tape may result in fire, so don’t use too much.

Step 8: Throw It

Throw it at something hard, but remember, it won’t work if it isn’t tight enough. Enjoy! 🙂

How to Make a Nerf Grenade Launcher and Grenades With NO Frisbee.

Introduction: How to Make a Nerf Grenade Launcher and Grenades With NO Frisbee.

Step 1: Materials Needed for Grenade Launcher and Grenade

Tools:
Dremel with a drill bit slightly larger than a paperclip’s diameter
Use a knife to make a hole is you do not have a dremel
Optional: A friend (makes things a lot easier or it can make you feel like you want to blow their face off. )

Materials:
Film canister (with lid ), I got a bunch from a local pharmacy that processes film for free 🙂
Spring; not too strong but not too week, you should be able to compress it with you fingers with only a small amount of effort
Big paper clip (we want length, not strength, but you don’t want it too bendy)
Party popper (Spring type), look at more of my instructables to see how to reset them so you can use them again or again (HINT click on my user name HINT)
Strong paper card that you need to cut up into circles (two or three) that fit inside you film can
Small bits of cut-up nerf darts (I just used some 1/2 inch FBR (Foam backer rod) from home-depot) or you could use airsoft BB’s

Step 2: Drilling Holes for Pin and Modding Spring

I used a dremel and drilled holes a cm down from the top.
I marked with a sharpy where the prongs of my paper clip would enter and exit and DRILLED PNEWWWWWWWWUPPP (sound my dremel makes)

Step 3:

Step 4: Ready to Fire

Insert the grenade into the launcher with the pin still IN. when you are ready to fire pull the pin of the grenade, DON’T THROW IT IF THE GRENADE IS IN THE LAUNCHER, TO FIRE THE GRENADE LAUNCHER WITH THE GRENADE IN IT PROCEED TO STEP 5 or just take the grenade out the launcher and throw the grenade (without the pin smart one!)

Step 5: FIRE.

If you have decided to keep the grenade still in the launcher (and not throw it) nothing should be happening. To fire the launcher aim the launcher, twist the bottom handle and BOOM the grenade should fly at the aimed area and explode, if not your enemy will grab the grenade and trow it right back at you so DO STEP 4 PROPERLY.

If you want to shoot the launcher with a gun mount (so you don’t have to hold it, it is just mounted to your gun) click here (it’s basically a AXE deodorant lid attached to a nerf rail mount)

How to Make a Cheap But Effective Airsoft Grenade

Introduction: How to Make a Cheap But Effective Airsoft Grenade

this is how to make a cheap but effective airsof grenade. Small than the waterballoon grenade, egg grenade, baking soda grenade, or anything you could go buy and just as effective

Step 1: Grocery List

alright part of these you can only get at new years or the fourth of july in america.

You will need some mighty crackers/ little dinamites about 1$ for 100

also some hot glue

and of course airsoft bb’s

Step 2: Starting Out

put some hot glue in a strait row down the mighty cracker
start a row of six on the mighty cracker place them quickly but as straight as possible
your going to do three of thes rows spaced evenly apart

Step 3: Now the to Fill in the Spaces

put some hot glue in one of the empty spaces and quickly put 7 bb’s in it alternating with the rows of 6 to maximize bb capacity without jeprodizing the strength of the grenade

Step 4: Last Step

now on the end without the fuse we are going to add 5 bb’s to the bottom
four corners and one in the middle (like the 5 on a die)

Step 5: All Finished

now we are done. we have a very effective airsoft grenade that is very small, whill also very cheap.

to light these i recomend you carry around a bic lighter or you can use two matches tapped to the fuse and a quick strike lighter

remeber that these may not be legal to use in your city limits since, they are infact firework

Can i use super glue and stone instead of bbs

Reply 6 years ago

You trying to kill someone?

This is a lot better then the pathetic vinegar and baking soda things. Finally something that explodes like a real grenade. You should make a pull pinn on the fuse by putting matches around the fuse and making a circle with the striker pad. Then put that over the matches and pull.

y dont u just use normal glue or super glue?

Reply 10 years ago on Introduction

The bbs stick together too much and shoot in only one direction.

Reply 11 years ago on Introduction

i have tried both but they both let the bb’s drop off while in your pocket or vest or watever, plus and this may sound a little weird, the firecrackers exsplosion helps the hotglue let go of the bb’s so it works better that way too

I’ve never seen grenades like this before but its a really neat idea!

um hot glue on a fire cracker? sounds dagerous.

Reply 11 years ago on Introduction

don’t worry it’s not as dangerous as it sounds although it has good range and shoots the bb’s pretty well, it won’t seriosly injure. i have been using this method for years

11 years ago on Step 5

sure i’ll try and get one done within the next week

11 years ago on Step 5

Could you add a video? I want to see the spread and effectiveness.

meh not enough bb to scatter

Reply 11 years ago on Introduction

hey you can add as many bb’s as you want this is just my version.

also i would like to tell everyone that these are much better when made with black cats cut of the strand. since black cats actually have a bigger explosion. this can be fixed by adding another mighty cracker or minimizing the amount of hot glue you put on them. and if you use a black cat cut off of a strand then add some longer fuse to it other wise it will blow up in your hand
