Nothing is more dangerous than sparklers and fireworks, sparklers are extremely sensitive and even the smallest sparklers can blow up whole cities.

Why did you said this,sir, you know, in fact it's not dangerous like your said, the real dangerous thing is that somebody used it unappropriately and get fireworks a wrong impression.

They are dangerous, I was a fireworks expert. The gun powder on the sparkler is very sensitive, it can be detonated if you even drop the sparkler firework. What do you knwo about fire works? NOTHING! Because you have not been in any pyrotechnics experience.

Ticky, we all read your highly uninformed post on explosives, and its very easy to see that you know almost nothing about explosives. Please top posting BS under the guise of being an "expert." I admit I am not an expert (this does not mean I know nothing, it means I don't have professional training/experience - there is a difference), but even with my limited knowledge of explosives, I can quite clearly tell you have no idea what you're talking about.

Lets explore some of your utterly uninformed spam from this thread as well as your comments here:

"Match heads are also as unstable as gunpowder, it can even ignite under it's own weight."
Ever shaken a box of matches?

"Molotov cocktails are often used in the army"
What army is this?

"Black powder is a high explosive and can be detonated with a slight impact of a feather."
It seems that as a fireworks expert, you'd know the definition of high explosives and detonation. Gunpowder is not a high explosive and does not detonate.

"Gasoline is a high EXPLOSIVE, it just takes a spark to detonate"
Again with the high explosive and detonation crap. It would seem an expert would know what these words mean.

"Thermite can detonate"
Yet again. *sigh*

"even the smallest sparklers can blow up whole cities"
Where do I get these sparklers that have the power of a nuclear bomb?

Quit spamming the forum with your BS. Even with my limited knowledge, I know your complete idiot when it comes to explosives knowledge

tickytickytackytac, I am not sure if you are a real fireworks expert. The Sparkling Wheel fireworks can be used on the stage, it's one of stage/smokeless fireworks and almost hasn't any harm. That's true. Please see the below URL:

You sir, are a dumbass. Sparklers do NOT have gunpowder. Gunpowder can be a variety of powders. Sparklers nor Gunpowder does not detonate. Sparklers are relatively safe. Those are all FACTS! NOT BS.

Is this a joke? This is so stupid, if you seriously think that sparkler can blow up whole cities, why do you think they sell them to childreen? If sparklers were WMDs, dont you think that we would have replaced the huge nuclear bombs with tiny, portable,light sparklers? This has to be a joke, I've seen many stupid people before, but not this stupid.

except that they're not. Black powder/gunpowder is an incendiary, not explosive substance. It can only create an explosion when it burns quickly in a compressed, enclosed space with no room to expand. In a sparkler, the powder is either contained within a paper tube-hardly resistant to expansion- or adhered to a wooden or metal rod. Neither method creates the containment necessary to cause a detonation. If sparkler's/gunpowder were potent enough to blow up a city, they would be used by military forces, which, last I checked, they aren't. The only device that can destroy an entire city is a nuclear bomb, which requires a critical mass of at least 50 kg of U-235 or 10 kg of Pu-239. They are not particularly sensitive, either, or I would not be able to slit them open to extract the powder. You, my dear friend, appear to be as much of an ignoramus regarding explosives as the fictional Luchesi is regarding spirits. Please cease your posting of incorrect, misconceived, and utterly pointless comments.

I'll second erichimmler on that, gunpowder doesn't detonate, it deflagrates. Check Wikipedia to back me up. One might gander that someone who "was a fireworks expert" would know the terminology.

Wikipedia is not always right--it's a free encyclopedia. People can post any crap they want. But i agree with the statement.

It's a video of a Catherine wheel, why did you post this? I like these, so I suppose it may be a popular effect...
