How can I keep the fire dep't from bringing negative energy into my party with &gross code violation& talk?
I can't recommend other than don't get water - if you add to a chip pan fire, for example, it will go whoosh. You are supposed to put a special blanket over kitchen fires.
Sure do. At the speeds that those things run even a small piece of stem could cause serious eye damage. Long pants, glove, hearing and eye protection. Saves a lot of heart ache in the long run.
I don't know what you can use to filter your spectrum, but I do know that Mylar is the best material to reflect light(95% reflective).
