<p>An inexpensive dummy bomb to be used in military maneuvers for preventing environmental damages to a maneuver ground otherwise caused by the use of bombs. The bomb has a shell (10) made from biodegradable gluten plastic. When a powder (30) explodes upon impact against the ground, the shell (10) is broken to fragments, which are degraded by underground bacteria. It is also possible to make targets from biodegradable gluten plastic.</p> |
