Shades of "The Anarchist's Cookbook." Half the stuff in there wouldn't work even if you made it spherical and in a vacuum. The other half was designed to blow up in your face. Or lap.
Probably one of the "match head" variants.
The original Anarchist Cookbook didn't have crap like that, it had stuff like recipes for making HMTD from hexamine tablets, citric acid, and hydrogen peroxide. I saw a copy back in the early 80's.
