Making Fireworks
<---- Lighting the Lances
This weekend I've made fireworks with the chemicals I bought during Skylighter's half off sale last week. I made a couple fountains, or as fireworks makers often call them, gerbes, with pretty good results. But the great appeal to me is to make "set pieces." This is an old time fireworks display where glowing and moving things are set down on the ground or against a wall instead of shooting them in the air. I feel they have this old, Victorian feel and I like that.
First and foremost among set piece fireworks are chemical lances which are a lot like railroad flares. The lances burn brightly for a minute or more. They're very bright and cheerful.
