What type of substance could this be?? (details)?

Question

I found about a pound or 2 of powder in a tupperware box with a coiled metal in the center kinda buried.

The powder was VERY fine, grey with a a greenish tint to it. It was very chalky and i accidentally touched it and it smeared all over my skin (like chalk) i dumped it out and the substance went EVERYWHERE. Oh and when i found it, there was a threat written on the box so I'm assuming that that substance could potentially be dangerous. I'm just wondering what it could possibly be???

Answer 1

it could possibly be an explosive- to test this, go to a secure, fire-proof area, and run a sparking fuse (electrical ignition) through a small sample of the powder and run a current through the wire. (JOKING) take it to the proper authorities and see what they say. If it was/ is an explosive, the metal coil could have been a remote detonator. Hope this helped
