20 fireworks in the air, slow/fast fuse

I wanted to put something together using the fuse available from pyrodirect.com. This set up uses both the slow and fast fuse. The first 10 shells were slow fuse and the last 10 were fast fuse. This fuse has a lot of fire and worked well for this application. Just trying to give a few ideas for the average backyard pyrotechnician to enhance their displays. . If you want to do this sort of thing you are going to have to purchase a mortar rack.
