AzoMittle Posted August 2, 2014 Share Posted August 2, 2014 All right guys I'm lost, been trying to figure this one out but not really sure how they did it. http://youtu.be/Yo5HTxMYOyw?t=5m20s How did they get this rising effect seen between 5:20 and 5:45? They have a tail that splits several times at what looks to be random angles. Is there a name for this? Oh and please watch the whole video, they have some really pretty shells. Very talented people. Thank you, AzoMittle Link to comment Share on other sites More sharing options...
nater Posted August 2, 2014 Share Posted August 2, 2014 (edited) Splitting Comets. They are tubes with a lift charge and fuse in the center and a star in each end. They are stacked like lincoln logs on the shell with different timings during the shell's ascent. They are mentioned in FAST and there is a tutorial for their construction on Passfire.

dagabu Posted August 2, 2014 Share Posted August 2, 2014 BTW- they are really easy to make too. They make a fun heading on a rocket spewing comets out as it rises. Crossettes are even more fun. I used discarded tubes and extra crossettes from a project. Link to comment Share on other sites More sharing options...
Zumber Posted August 2, 2014 Share Posted August 2, 2014 Yes there is information on this in Shimizu FAST book.see FAST book for reference also see attatched image. 1 Link to comment Share on other sites More sharing options...
pyrokid Posted August 2, 2014 Share Posted August 2, 2014 Is it challenging to seal the tubes in a way that allows the comets out and protects them from the lift? Link to comment Share on other sites More sharing options...
Zumber Posted August 2, 2014 Share Posted August 2, 2014 (edited) No.just press cardboard disk like you press while making cakes.and close end with kraft paper and glue.zoom on attached image I added in previous reply.

AzoMittle Posted August 2, 2014 Author Share Posted August 2, 2014 Huh, very cool. For those interested it is section 20.3 in FAST, also called Kyoku-Do. So do you load it in the mortar with the comets down? I imagine that breaking down on the lift. Or would you top fuse it with QM? Link to comment Share on other sites More sharing options...
nater Posted August 2, 2014 Share Posted August 2, 2014 Rising effects are on top of the shell, the lift is on the bottom. The shell is loaded properly. The rising effects light from the hot gasses at lift. Link to comment Share on other sites More sharing options...
Mumbles Posted August 2, 2014 Share Posted August 2, 2014 A member here has made some really nice ones too. You can see the whole shell, lift included, here. Also, Kyoko-Do just means rising effects. It's not specific to these splitting comets, despite some people's usage of it. http://www.amateurpyro.com/forums/gallery/image/1060-12-shells-with-rising-effects/ 1 Link to comment Share on other sites More sharing options...
