Answer 1

Smoke bombs are a firework designed to produce colored smoke upon ignition. While there are smoke generating devices that are dropped from airplanes, the term "smoke bomb" is typically used to describe the three varieties of smoke devices:

Smoke balls - hollow, cherry-sized spheres of brightly-colored clay filled with a smoke composition. They produce a forceful jet of colored smoke for 10-15 seconds.
Smoke candles - (also called a smoke generator or smoke canister) cylindrical cardboard tubes with a fuse, usually 1½ inch (37 mm) in diameter and several inches long and looking like a giant firecracker. Such devices create a thick cloud of smoke for up to several minutes. Uses include providing smoke for smoke testing and creating a smoke-screen for paintball and airsoft games.
Smoke canister - A metal can that releases smoke when a pin is pulled. Used for signalling by military personnel.
Colored smoke devices use a formula that consists of an oxidizer (typically potassium chlorate, KClO3), a fuel (generally sugar), a moderant (such as sodium bicarbonate) to stop the reaction from getting too hot, and a powdered organic dye. The burning of this mixture evaporates the dye and forces it out of the device, where it condenses in the atmosphere to form a "smoke" of finely dispersed particles.

A simple smoke powder can be made by gently heating potassium nitrate and sugar in roughly a ratio of 60% KNO3(saltpeter/potassium nitrate) and 40% sugar. The more finely ground the saltpeter and sucrose, the better the smoke bomb. Care should be taken not to let the mixture (which, when ready, will look like sticky lumps) get too hot when heating. This formula has another very similar variant in which the ingredients are left in powder form and the granulated sugar is replaced with Icing sugar.

Difficulty can be encountered in igniting the saltpeter/carmelized sugar mixture, and "cooking" the smoke bomb can also present a hassle. More success could potentially be enjoyed when one adds another flammable substance to the mixture without "cooking" it.

Devices or cartridges containing only the dye are used with an external heat source in a smoke machine.

In the military, smoke bombs are one of the means for creating smoke-screens.

The most ingenious method is this: Use a large upside-down glass. Fashion a holder for your "tobacco" from a screen from the inside of a waterfaucet that is proped up by a large paperclip _under_ the glass in such a way that you can reach under there with a long match and light the material. There are special matches available at some hardware stores for lighting older stoves and furnaces that work well for this project. Have a soda straw ready. This requires some skill, but can be done without smelling up your house if done properly. Have your soda straw ready! Light the material under the glass, with the upside-down glass slightly raised above a FLAT tabletop to let in just enough air to support combustion. When the glass is filled with smoke, and not yet pouring out from under the upside down glass suck it out quickly with the straw and then close the glass down on the tabletop. We did this in college, and it worked extremely well - it works best however with resinous mixtures such as kiefe or guess what else. If you have a leafy blend, clean it carefully, then pack it in the screen before you set it up under the glass for ignition. Get it?
