Here are a few shots of us helping make the pyro effects. Below is one of the spinning pinwheels. You can see two rockets, and that's a type of fuse called quick match (burns around 60 feet a SECOND) that has the two leaders going into middle where the fuse has been totally exposed so it's just essentially gun powder on a string. As soon as any lighted pyro hits the very middle, it lights the whole thing up and it starts spinning like crazy, making a beautiful round nest of sparks.
With a bunch of happy pyros on the assembly line, it didn't take long to get everything prepared. Now came the hard part - waiting until dark so we could start shooting!
