Ammonal
From Academic Kids
Ammonal is an explosive mixture of ammonium nitrate, aluminium dust and stearic acid. It's misused since it uses ammonium nitrate as oxidizer and aluminium as fuel, but ammonium nitrate is a high explosive itself (though it's hard to detonate). It also has the problem of ammonium nitrate being highly hygroscopic. It burns when open, and detonates when confined.
