The powder is so dry that it risks self-ignition just by looking at it. And not the kind of explosion you can harness to parlay that energy into something useful, but the kind that blows up in your face and ignites your garage into flames, risking losing your house.the powder is so dry, but it does no good if you never use it. This is the big one for me.
At the very least, we could have at least used it to have a fun, yet controlled, explosion in the backyard. That would have been a better idea than inadvertently setting the house ablaze.
