Unique lighting?

I am looking to shoot some UW portraits. I have seen a lot of people using simalar lighting setups. I am looking to try out some "UnOrthodox" lighting. Has anyone ever used a flare, sparklers, bright glow sticks, or fireworks? Any thing that burns bright, and still works underwater? Is this a bad idea? Sure these things get hot, but if used in a way that the model does not actually touch them, it may look cool.
