folks the durga puja is just coming and this time we cant use crackers which causes sound pollution so its better to use something else, a whole new kind of cracker which does not causes any sound pollution.actually we wont find it in any stalls but we can make it! Its easy and fun, try it out....
You can make an effective smoke bomb quite easily. There are even colorants you can add if you want to make colored smoke. Let's start out with instructions for the easiest/safest type of smoke bomb you can make:
Smoke Bomb Materials
* sugar (sucrose or table sugar)
* potassium nitrate, KNO3, also known as saltpeter
* skillet or pan
* aluminum foil
Once you've gathered your smoke bomb materials, it's easy to make the smoke bomb.
1. Pour about 3 parts potassium nitrate to 2 parts sugar into the skillet (5:3 ratio is also good). Measurements don't need to be exact, but you want more KNO3 than sugar. For example, you can use 1-1/2 cups KNO3 and 1 cup sugar. If you use equal amounts of KNO3 and sugar, your smoke bomb will be harder to light and will burn more slowly. As you approach the 5:3 KNO3:sugar ratio, you get a smoke bomb that burns more quickly.
2. Apply low heat to the pan. Stir the mixture with a spoon using long strokes. If you see the grains of sugar starting to melt along the edges where you are stirring, remove the pan from the heat and reduce the temperature before continuing.
3. Basically you are carmelizing sugar. The mixture will melt and become a caramel or chocolate color. Continue heating/stirring until the ingredients are liquefied. Remove from heat.
4. Pour the liquid onto a piece of foil. You can pour a smaller amount onto a separate piece, to test the batch. You can pour the smoke bomb into any shape, onto an object, or into a mold. The shape and size will affect the burning pattern.
5. If you aren't going to clean your skillet immediately, pour hot water into the pan to dissolve the sugar (or else it will be harder to clean). Clean up any residue you may have spilled out of the pan, unless you want mini-smoke bombs on your stovetop.
6. Allow the smoke bomb to cool, then you can peel it off the foil.
Now that you've made your smoke bomb, it's time to light it.
The solid smoke bomb material is flammable and can be lit directly. You can light your smoke bomb using a lighter. Only light your smoke bomb in a well-ventilated area, on a surface that won't catch fire. The smoke bomb will burn vigorously (more slowly with a higher percentage of sugar) with a purple flame.
Alternatively, you could place a short length of fuse into the smoke bomb when you pour it, and then light the fuse.
