A firecracker, also known as a cracker, bunger, or mise
maker is a small explosive mostly designed to produce a significant amount of
noise (with a loud bang) with a visual effect.
The material has a fuse and a well wrapped heavy paper
casing that contain an explosive compound. It is easy to make and fun as well.
It also offers a way of learning the science behind the firework theory.
Before
making the firecrackers, here are some few ingredients that you need:-
- Black powder
- Charcoal
- Potassium Nitrate
- Sulfur
- Flash paper
- Nitric acid
- Cotton
- Kitty litter
- Fuse
- Tape
- Pencil
Assembling
a homemade firecracker is easy; here is a step by step procedure of making that
light sparkle up.
1. Using one of your fingers measure the length of the
firecracker you need.
2. Place a pencil on a paper and roll a strip of flash
paper or cardboard to make a hollow tube. Using a tape, hold the paper in shape
and remove the pencil to leave a space.
3. Cut the pipe into one or two inches sections.
4. Once cut, tape the bottom of each tube to seal it.
5. Add small amounts of clay and kitty litter to the
tube. Use the pencil to press the clay into the bottom. Using the eraser end of
the pencil, make a plug.
6. Add nitrocellulose or black powder into the tube.
Insert a piece of pipe and continue adding power till you are near the top. Add
a lot of powder to make sure enough is exposed and can light it quickly and get
away from it.
7. When you are done filling the powder, there are many
options you can use to seal the tube. When working with paper, if you plan to
light the firecracker immediately, then, you can firmly twist the paper and
fuse it to seal the cracker. Another great option is to top off the gunpowder
with small amounts of kitty litter. After that, you tape the top of the
cylinder and leave the fuse top-end exposed. Finally, you can tape the top of
the firecracker and blow a fuse exposed. Work with your limits by experimenting
all models and seeing which works best for you.
For
your safety, here is information to keep in mind.
- Working with highly explosive materials can be disastrous. Nitrocellulose and gunpowder are highly flammable if they are under pressure when they burn. (Ensure the materials only explored when ready by keeping them away from flame and heat)
- Keep it out of reach of children. It’s a firecracker! Let an adult handle it.
