Patent ID: 7083414

Claim:
An explosion simulation device comprising: an elongated body formed with a hollow chamber, said body being formed with end apertures at opposite ends thereof and a plurality of radially-directed side apertures along an axial length thereof, a bottom of said body being formed with at least one flat surface which serves as a movement stabilizing surface, said end apertures and side apertures being in fluid communication with said hollow chamber, wherein said side apertures are arranged in two or more radially-spaced parallel rows and no said side apertures face downwards when said movement stabilizing surface is placed on a resting surface; a pyrotechnic substance disposed in said hollow chamber; and a detonator disposed in said body for detonating said pyrotechnic substance, wherein said end apertures and side apertures are arranged with respect to one another such that forces of post-combustion gases, formed as a product of detonation of said pyrotechnic substance and which are vented through said end apertures and side apertures, are directed in directions that tend to cancel movement of said body.
