Thanks for the ideas. I really like the idea of the color coding Hazmat lables. Kids wouldn't have any idea what they meant but the warning would be there for those with a need to know.
As for temperatures, lots of testing has shown that the inside of your nice black car sitting out in the parking lot in the Phoenix sun with the windows rolled up will get up to a little over 175 degrees F inside. That's when it's 116 degrees F outside. :grin:
If we were talking about Smokeless Powder, I would agree with the statememt "Powder needs containment to go "BOOM".
10 lbs. of powder in a pile may sizzle and "swoosh" a good deal, but no boom."
As I understand it though, Black Powder is an Explosive and does not need to be confined to burn at an explosive rate. That, and its 450 degree ignition temperature was one of the main drivers in the creation of Pyrodex.
What is interesting to me so far is this is the First Idea I have come up with that my wife totally agreed with. Based on past history, I expected a major battle with her but she was almost leading the parade saying things like "...or you could put it over there..." :rotf:
Like some of you have pointed out, I am not the only one concerned so keep those ideas coming.
