Abstract
Abstract A method and composition for enhancing the visual effect of a combustion explosion without substantially increasing the explosive force is the subject matter of this invention. A solid explosive compound is combined with a ground combustible particulate material that is characterized by a wide distribution of particle sizes. Preferably the surface area of the particles will vary by a factor of at least 500 percent and no more than 10 percent of the total number of particles will be represented by any one particle size.
