- There explosion takes place in two stages. The first is an ammonium nitrate
- explosion that disperses the aluminum and polystyrene. I believe that the
- polystyrene also acts as a reducing agent with respect to the aluminum at
- this point, reducing any oxides. In the second stage the finely-dispersed
- aluminum spontaneously combusts with atmospheric oxygen. Ergo, fuel-air.
