madmandotcom Posted December 3, 2012 Share Posted December 3, 2012 hi, i was at a professional display over the weekend and saw an interesting burst where 3 shells were launched simultaneously and when the burst, they were TT, however, in the overlap of the burst, there was a colour change, and only in the overlap was the colour change, i have been wondering ever since, how the heck did they do that?also, on an unrelated note, do you think that displays should be symmetrical or asymmetrical?

AirCowPeacock Posted December 3, 2012 Share Posted December 3, 2012 I like symmetry. Shimizu goes into great detail about symmetry and other stylistic effects in his F.A.S.T.. Link to comment Share on other sites More sharing options...

Both depending on the shell type and design. I like ball shells to be mostly symmetrical but I rarely see a canister shell that is truly symmetrical and most are heaving inserts in rings which are certainly symmetrical as rings but not as spheres. -dag Link to comment Share on other sites More sharing options...
cogbarry Posted December 3, 2012 Share Posted December 3, 2012 It's art, so it's a bit hard to call different ways of doing things right or wrong. Having said that, I personally get sick of seeing display operators lighting (2) visco fuses when they have no idea what the shells are or how they may look together/on top of each other. I like to pair some shells up, yung feng assortments come in boxes with two of each shell. If you tie these shells together and fan them out, you can put two like shells up with symmetry and IMO it looks like you know what you are doing. There's a good example of how symmetry can be used. Like Dag said, cylinder shells are different, they are multi break and IMO, designed to look good by themselves. Most modern displays are set up with more shells but most are single break ball shells. This changes the set up and the whole game to some degree.

nater Posted December 3, 2012 Share Posted December 3, 2012 Both symmetry and asymmetry have their place in a display. It all depends on the artistic effect you want and both are appropriate. It would be awefully boring if the whole show was mirrored without any variation. Good show design uses the sky from the ground up and from left to right. When you have the space, depth from front to back can be used very effectively as well. Link to comment Share on other sites More sharing options...
Algenco Posted December 4, 2012 Share Posted December 4, 2012 hi, i was at a professional display over the weekend and saw an interesting burst where 3 shells were launched simultaneously and when the burst, they were TT, however, in the overlap of the burst, there was a colour change, and only in the overlap was the colour change, i have been wondering ever since, how the heck did they do that?also, on an unrelated note, do you think that displays should be symmetrical or asymmetrical? I don't see how that could be possible, it would require a very narrow vertical band of color changing stars on the sides.The shell would have to be loaded with those sides facing each other and the shell would somehow need to be prevented from turning/spinning in the air.I just don't see how thats possible is it possible what you saw were Ghost shells? That's the only thing I can think of that might give such an illusion Link to comment Share on other sites More sharing options...
chemtech89 Posted December 5, 2012 Share Posted December 5, 2012 That really sounds amazing! Im glad someone finally posted in regard to the color change. It would be great if you had a video that we could dissect. You don't happen to know the name of the company that put on the show? Or if you don't mind sharing the location, it could be back tracked to find out. If we know where it was, we could search youtube to see if someone else got a video. ie "somewhereville firework show 2012" very interested to see..

mathiasxx94 Posted January 10, 2013 Share Posted January 10, 2013 Amazing video Mumbles, the star rolling have to take time and patience I don't know, but maybe the effect madmandotcom saw was caused by peanut shell, the two shells can at least not turn relative to each other Link to comment Share on other sites More sharing options...
pyroshell Posted January 10, 2013 Share Posted January 10, 2013 By the title I thought you guys were talking about those color burst ( as in the actual burst charge) , but it seems like you guys are talking about something different. Link to comment Share on other sites More sharing options...
NightHawkInLight Posted January 11, 2013 Share Posted January 11, 2013 (edited) Sounds like an inner petal that had a thick coat of dark prime so that it didn't show itself for a while. Edit: Never mind, I misunderstood your description. Edited January 11, 2013 by NightHawkInLight Link to comment Share on other sites More sharing options...
