Have you ever been stuck at home on New Year's Eve night with nothing to do? Here you can learn how to make an artificial fire called Cremora Fireball at home. They are easy to make and exciting to watch.
Steps
Step 1. Make a hole in the bottom of an empty can
You need to take a can with a capacity of 33 to 83 cl. Most soup or coffee cans are fine. You have to make sure that the inside of the can is completely smooth, otherwise the contents will not be properly shot upwards.
The hole should be the diameter of the size of a fuse (usually about 2-3 mm)
Step 2. Insert a 10 cm fuse into the hole made in the bottom of the can
It's fairly easy to find firework fuses at hardware stores or DIY stores. Visco fuses are the most common and recommended for home-made fireworks.
Once the fuse is in place, place the can on the ground
Step 3. Put the black powder or smoky powder inside
You can find them on the market or you can produce them at home. Make sure the black powder is spread evenly across the bottom of the can. It must completely cover the bottom with a layer of at least 1 cm.
- The best way to determine the amount of black powder needed is to consider 1.15g. each cm. square of the base of the can. For example, with a diameter of 5 cm. you need about 22, 55 gr. of dust.
- To make black powder: fir or pine wood, also called "white wood", is considered the best wood for making charcoal, and has the characteristic of maintaining the ability to make sparks for a long time. You need to burn wood in your home fireplace or on a barbecue. Fill a large pot with fir or pine wood and set it on fire. It will take 2 or 2 1/2 hours to turn the wood into charcoal. As you know, the coal is ready when the hot gases no longer come out of the lid. Before shredding it, let the charcoal cool (it is usually left to rest overnight). When you have chopped it, it is ready to use.
Step 4. Cover the hole with a piece of tissue paper cut out in a circular shape
The tissue prevents the flammable powder from mixing with the black powder, otherwise it would significantly decrease the flammability degree of the black powder. The black powder must burn quickly to produce enough force to push the flammable powder into the air.
Step 5. Without pressing too hard, fill the can 1/2 or 2/3 full with the flammable powder
Although this type of fireworks is called as the Cremora milk surrogate, it is actually quite difficult to find nowadays, so a number of substitutes are used. Make sure it is well sieved and without lumps.
- As a substitute for Cremora you can also try to use soluble coffee powder, icing sugar, or even very fine sawdust or wheat flour.
- The more flammable powder is sieved finely the longer it will last. If it has any lumps, sift it through a kitchen wire mesh strainer before using it. It will help you break down the biggest lumps.
Step 6. Light the fuse and quickly move away at least 10-15 meters
The bigger the can, the farther you have to go. You might also want to do a few rehearsals before inviting your friends to the show. This way you will get a better idea of how this type of fireworks works and what steps you must take to avoid any type of accident and to avoid injuring someone.
Be careful not to place fireworks near flammable objects such as dry grass or wood, nor inside your home (or inside your neighbors' house)
Advice
- It is best to build your own firework right before using it, since otherwise the dust could settle causing the can to explode in place of its contents.
- If you are looking for something sparkling without taking all the risks and dangers associated with an artificial fire, take a look at how a rocket is made with matches.
