matandch,
If you're interested to know in the way the competition is setup for each display in Montreal, then you can visit this link on this site. It's in the "Information" section of this site. I'll put the link:
http://www.montreal-fireworks.com/setup.html
Very detailed and great for understanding the "behind the scenes." You might also want to read about the other sub-topics in that section, especially the "projects" area. This gives an analysis of how a rocket is done and considering that you have an interest in rockets. Of course, rockets are used in our competition and in a great variety, too.
You'll be surprised at what goes on in our competition! Enjoy!
Regards,
Trav.
