Disney Goes Boom!
BoomZilla writes "Reading Disney's alliteratively titled Practically
Perfect Pyrotechnics introduces the latest in firework launch technology.
Gone are the 'light blue touch paper and retire a safe distance' days. Shells
are now launched using compressed air. No burning black powder means no smoke
drifting over the residential neighborhoods, plus a safer show. Best of all the
new system is more precise and can launch shells higher than black powder,
enabling spectacular new effects. An additional article:
The future of theme park fireworks
covers some of the pros and cons of compressed air launch systems." We mentioned this earlier.
The air in the Los Angeles/San Bernardino area can be pretty awful, which probably has a lot more to do with their efforts to decrease smoke. I visited the Grand Canyon years ago and heard sometimes the visibility, in the summer is so poor you can't see across the canyon, thanks to smog from San Diego and Los Angeles/San Bernardino, hundreds of miles to the west. (Fortunately I was there in winter, which I highly recommend (South Rim open only), with 200+ miles of visibility.)
A word of advice: Try to avoid a down-wind position for fireworks as sulpherous ash may drift down into your eyes and it burns like H2S.

Perhaps Disney would give you some of their leftover black powder pyrotechnics and you could take care of that upper balcony.
If I could, I'd destroy you all.
I just find it amusing that Disney released all this news about their revolutionary, wonderful new launch system and then proceeded to roll out a new pyrotechnic show at Disneyland that, by all accounts, is disappointing at best compared to the one it replaced. Sure, it may be less polluting, but it's also a lot less fun.
Sure, there are other factors that caused the switch in shows, but the timing was unfortunate. They basically managed to associate environmentally friendly fireworks with totally boring fireworks, which, by an inspection of their description of the new launch technique, really isn't the case at all.
When it goes all the way down the street, and rolls under a neighbors car, still on fire...the decision to go get it or run is a tough one.
(don't ask how I know this)
A typical 8" shell weighs about 3 pounds, of which about 1 ounce is the lift charge. Most of the weight comes from the shell casing (pressed glued paper) that holds the burst charge and the stars and keeps them together long enough for the stars to ignite when the timing fuse burns through to the burst charge. Disney is probably using 4" shells for most of their stuff, so figure a pound of shell with a tablespoon of lift charge.
For reference, the largest shell ever fired (the 36" Fat Man) weighed 800 pounds and was lifted 1400 feet in the air by 1/2 pound of black powder.
Life, the Universe, and Everything... in my image.
I imagine someone in a location where fireworks are legal could rig up a poor mans version using something similar to a Potato Cannon (the pneumatic type).
Correct. These are the same people you read about in the Darwin Awards.
Ironically, the word ironically is often used incorrectly.
When I read this article the first time, I emailed it to a friend of mine who works in the Pyrotechnics division at Disney World, and he replied saying that he didn't know what prompted them to write that article when they did -- Disney has been using that technology for several years now. Oh well, I guess old news is still news. Maybe it was just a slow news day the first time /. had that article, and an even slower news day this time...
Now with improved accuracy Tinkerbell becomes a more formidable target.
can't sleep. clowns will eat me.
Who cares about the fireworks. Just think how far one of those compressors could launch a potatoe! This also presents an alternative to traditional guns. Forget plastic bullets, now you can kill/knockout your enemys with enviromentally friendly, biodegradable food staples. Where can I get one?
There is a big difference between what's right, and the results of the US legal system.
Example: Small airports were built all over the country. Decades later, the land around them was made into housing developments. Then people sued to have the noisy airports restricted to the point they were no longer viable, or shut down altogether. They consistently win, because there are 100 irate homeowners vs. 30 people who want to preserve the pre-existing airport. Bye-bye airport. The ultimate irony is when the runway becomes the main street through the new subdivision that's built where the airport was, and all the subdivision streets have names like Blue Sky Place and Lindbergh Drive.
It's similar to developers leveling a beautiful stand of trees to pack as many little vinyl houses as possible into a congested suburban hell, and naming the subdivision Aspen Acres. I guess Fugly Houses Estates doesn't sound very good.
Maybe I'm getting even more cynical in my old age, but there seem to be fewer and fewer instances where Right and Reality coincide.
