I don't have much experience with either, but I would add that scanning is more like taking the bus from Wall Street to Washington Heights at rush hour with lots of wheel chair people getting on and off. That may make you want to set off a bomb though.
Cristian,
I once had a smoke bomb go off in my kitchen. I stole about a kilo of Potassium Nitrate from my high school chemistry class so figure I'm perhaps 16-17 years old. My first bomb was the size of a 6 ounce juice can and when I lit it off in a park. It made a surprising amount of thick dense smoke. It really impressed some of my friends.
If I remember the formula correctly it was five parts sugar to one part Potassium Nitrate (a strong oxidizer). The idea was to use a strong oxidizer to make all the sugar kinda burn all at once, but the bomb had to be "cooked" by heating it on a stove slowly until it congealed into a pudding that would turn solid upon cooling.
A few match heads sprinkled on top was all that was needed on top to ignite the smoke bomb and work as a fuse, and all that was needed for rapid ignition was a flame. It was recommended that a double boiler be used, but I was clever and able to make that small prototype without one.
Well things didn't go so good with my second improved large version. My plan was to make a scaled up production model that would fill a 3 pound coffee can. I turned on the stove and before I could get a chop stick from a drawer to stir the mix and prevent any burning the concoction became like Mount Saint Helens in my kitchen at home.
The idea of mixing sugar with an oxidizer is to have rapid burning of a solid, but since I had a granulated mix I had a combination of a flame thrower and a volcanic eruption that included hot flowing lava that set the ceiling on fire, covered the stove in thick black crust, and burned the linolium floor.
Might I say the house became filled with thick choking smoke. You should of heard my father, a poor illiterate Chinese immigrant, shouting and cursing in Chinese. I went in the basement and got a fan to blow the smoke out of the house with our small Cape Cod in the Long Island suburbs with the front door chocked open. Then our neighbor called the fire department. This is one of the reasons why I was my father's favorite. LOL.
Anyways you got to understand the culture back then. It was the early 1970's and I was a hell raiser.
A funny thing happened to my friend Bobby Mac shortly thereafter. Bobby had witnessed my prototype in the park, he too stole some Potassium Nitrate from chemistry class, and he too had an eruption in his kitchen at home with similar results.
My old boss at Grumman had a business doing real fireworks shows in southern New Jersey. The finally was timed by a long fuse that set off "shells" from launch tubes that were four, five, six, eight and even twelve inches in diameter; but the body of the show involved a two teams of two loaders along with a guy with a road flare who manually lit off four and five inch motor rounds as fast as they could. I was one of those loaders. Keeping low while running while shielding the quick light fuse on the shell I was carrying with my body as hot burning embers descended all around me.
BTW there's a lot of smoky ash descending and the "magazine" that stored all the shells for the show were held in nothing more than a plywood box the size of a storage trunk. Every once in a while a dude would not launch, and it was standard procedure to just place the next shell on top of the dude laying in the mortar with the hope that the top shell would ignite the dude to clear the mortar.
Anyways, because of my personality, and because I'm an artist, there are a lot of things I experienced. Guns are another story.

EDIT: I said I was perhaps 16-17 years old, but the fact is that I was perhaps 15-16 because I was in 10th grade.
