Don't store them in your car or house. Call EOD asap!
Are you kidding me???? And miss out all the fun in burning it?

Yeah, I am serious, lol. There were ten sixteen-ounce cans of FFF Superfine Black Rifle Powder, and what a time I had. First I poured a small pile into a piece of tissue paper, then set fire to it. You know, to see if it was fresh powder? It was, I guess, since it went POOF and all that was left was a black smoking sheet of tissue paper smoldering on the ground. Then I went into a field and made a trail of powder leading to a can's worth of powder, and lit the end of it. I tell you, I was astonished at how quickly the whole thing lit up, and the amount of smoke generated. I repeated the process with the rest of the powder, and created a mini mushroom cloud. Hide me. :P
