Hey Yelp,

I did the same thing as you and cut a Mag block down to a smaller size with a hacksaw. I then held the shortened magnesium block on my knee and filed the edges smooth, this left a very small pile of magnesium on the top of my pants.

"I wonder if that would light if I struck a spark", D@mn that stuff is hot! I burnt a hole through a good pair of pants and got a 1/2 inch blister on my skin. Not the stupidest thing I have ever done, but getting there.

Mike
