Aim
To Prepare a Smoke Bomb
...
Smoke bombs are useful to military
units, self-defense and pranks
...

Colored smoke devices use a formula that consists of an
oxidizer (typically potassium chlorate, KClO3), a fuel
(generally sugar), a moderate (such as sodium
bicarbonate) to keep the reaction from getting too
hot, and a powdered organic dye for color
...


Material Requirement
• Sugar
• Potassium nitrate, KNO3, also known as saltpeter
• Skillet or pan
• Aluminum foil or a used tissue paper roll
• Fuse for easy ignition (from fireworks)
• Cotton and tape
• Burner

Procedure
1
...

Measurements don't need to be exact, but you want
more KNO3 than sugar
...
If you use equal amounts
of KNO3 and sugar, your smoke bomb will be harder
to light and will burn more slowly
...

2
...
Stir the mixture with
a spoon using long strokes
...


3
...
The mixture
will melt and become a caramel or chocolate color
...
Remove from heat
...
Pour the liquid onto a piece of foil or into the
cardboard roll
...
You can pour
the smoke bomb into any shape, onto an object, or
into a mold
...

5
...
Clean up
any residue you may have spilled out of the pan, unless
you want mini-smoke bombs on your stovetop
...
While the mix is still hot, push a pen lightly down
the mold and don’t remove it
...
(About an hour) Now, remove the pen and
insert the fuse
...
Secure the fuse with cotton
...
Smoke screens are usually used by infantry to conceal
their movement in areas of exposure to enemy fire and to
conceal a withdrawal
...
Another application is in smoke grenades:
Smoke grenades are canister-type grenades used as groundto-ground or ground-to-air signaling devices, target or landing
zone marking devices, or as screening devices for unit
movements
