You can use air compression if you can't find fireworks.  Rig something to blow its top and throw some top cover into the air.  Sound effects will add to it.  The container could contain smoke that you've trapped in it to release.

All military electronics are hardened against EMP. It would knock out civilian electronics by inducing a high amplitude current spike into the circuitry. (I used to work on military aircraft electronics)\n\nBasically, in a nuclear war scenario, the first detonation would be a high altitude blast, which would wipe out most electronics - communications being the main target.\n\nNot sure if there is any other method of doing it, like the Bond flick 'Goldeneye'.

Conventional bombs are essentially a very violent chemical reaction, usually a very fast oxidation or a rapid decomposition of a very unstable compound.  In any case, a tremendous amount of heat is generated that causes a very fast expansion.  Aside from the heat generating a potential fireball, the rapid expansion creates shockwaves through the air and whatever other matter is in close proximity to the bomb.  It is this shockwave which does the most damage.\n\nAtomic/Nuclear weapons are a bit more complex, though the principles are essentially the same.  The chemical reaction is replaced by a nuclear chain reaction known as fission.  This produces a truly astronomical amount of heat, resulting in a mammoth shockwave.

Fireworks, which are also known as pyrotechnics, are basically devices that contain burning compounds. The most common type of display firework is the aerial shell, which is fired from a mortar tube. These fireworks typically have four components: a lift charge, a time-delay fuse, a breaking charge and a light/effect generator. The lift charge is generally black powder, a compound that burns rapidly and propels the shell from its tube. The lift charge also ignites the delay fuse when it fires. The delay fuse is usually a black powder fuse with a delay of a few seconds, and it is designed to ignite the break charge when the shell reaches the appropriate height. The purpose of the break charge, which sits at the center of the lofted shell, is to explode, thereby igniting and scattering the shell's contents. This break charge is generally finer-grained black powder than the lift charge and more highly confined, which causes the shell to explode. The payload of the shell usually comprises small spherical pellets of pyrotechnic composition designed to generate light. These capsules burn from the outside inward, and color changes are obtained by layering different compositions on top of one another.

The technique is called LAPES -- Low Altitude Parachute Extraction System -- and is still used (though infrequently) by the U.S. Army Airborne.  It is useful for delivering large loads to a contested landing strip.\n\nThere's a terrific video out on the web that shows the misadventures of some airborne and :APES drops.  If you can find it, it is worth if for the laughs, especially the shot of the cargo vehicle that breaks free from its skid and goes free-wheeling off into the sunset!

Celestine is sometimes used to produce a red color in fireworks. Charcoal (carbon) is also used in pyrotechnics. Charcoal from soft woods, such as grape vine or willow, is good for fast-burning compositions like black powder, whereas charcoal from hard woods like pine are used to create long-lasting spark effects. \n\nIn any laboratory setting proper personal protection equipment should be employed. I recommend using safety glasses, a laboratory coat, full length pants and latex/polyethylene gloves. You shouldn't wear open toed shoes and loose articles of clothing that could snag. In cases were an explosion is possible, proper shielding is required. A fume hood is also required if hazardous fumes are expected.\nAlso, if you are resorting to using an online forum to recieve answers to potentially dangerous reactions, you obviously do not know what you are doing and should gently place down your little pyrotechnics and slowly back away.

A scramjet is a 'supersonic combustion ramjet'. To understand its operation, it's best to look at the evolution of jet engines.\n\nThe least sophisticated, lowest power jet enjines are called pulsejets. They can be built out of metal sheet or tubing in a garage; in fact there is a fellow in New Zealand who has a website describing how to build one, and shows it being used to power cars and even has plans online to build a pulsejet-powered cruise missile guided by GPS. The German V-1 "buzz bomb" cruise missile was powered by a pulsejet, and the pulsejet's distinctive sound resulted in the name.\n\nNext up in sophistication is a turbojet. Unlike a pulsejet, it has a continuous stream of air flowing through, leading to continuous power. It works like this: Air flows in the front of the engine, where compressor blades drive it backward, thereby increasing its temperature and pressure. The fuel is injected into the stream of hot high pressure air and ignited, making it (of course) much hotter and higher pressure still. Those hot expanding gases shoot out the tailpipe of the engine, providing thrust. On the way out the tail end of the pipe, the gases drive another turbine, which is connected by a shaft to the compressor turbine. In this way part of the energy of the engine drives the compressor stage. This is why it's called a turbojet. Turbojets have a hot, fast, dense exhaust which creates turbulence as it mixes with the cool, stationary air around the engine. That is why turbojets are very noisy and not very efficient.\n\nSome of the shortcomings of a turbojet are addressed with turbofan engines. These are similar to a turbojet in construction, but the compressor blades are larger and they are ducted around the turbojet core. This "bypassed" air, which does not have fuel burned in it, is intermediate in temperature, pressure, and speed between the air outside and the air flowing through the core of the engine. This increases the power of the engines and makes them much quieter. Turbofan engines are the most common type of jet engine today.\n\nThe problem with turbojets and turbofans is their complexity, which limits the speeds they can attain because of drag from the turbines. The ramjet was invented to overcome this limitation. It has no turbines; it is basically a hollow tube with a cone in the front which air passes around. The ram pressure of the air entering around the cone acts like the compressor stage in a turbojet. Ramjets have less internal drag than turbojets so they can travel faster. Unfortunately, they do not work at all below high speeds since there is no ram air pressure at low speed. Ramjets require other jets or rockets to speed them up to operational speed.\n\nA scramjet is a ramjet in which the air passing through the engine is at supersonic speed through the entire engine. Normal ramjets have to accelerate the air passing through so they travel through the engine at less than Mach 1 compared to the speed of the plane; otherwise the shockwave inside the engine causes a flameout. Scramjets are designed to work despite the shockwaves, hense "supersonic combustion". Since it can accommodate the highest speed airflow, it can power the fastest aircraft of all these engine types.

Well, it helps to know what the application for the system will be, but the most common is for CGI/rendering in computer games.  Particle systems in this sense are used to model things that don't work with traditional surfaces and textures - Things like fire, sparks, plasma.  It gives them a much higher level of realism.  In a research context, particle systems are created and used to model airflow among other things.
