The German Pandora weapon was a development of Dr. Zippermayr's coal-dust research in Lofer, Austria during the war. Having worked on the Wind Cannon, Vortex Projector, and even a small turbojet aircraft with a unique wing called the Pfeil, Pandora emerged as a coal-dust firing artillery piece adapted by the SS for use in the Warsaw Ghetto. It was used against the resistance fighters hiding in the rubble and in intact buildings. Pandora was a 50mm weapon with a delayed charge that when detonated caused massive damage and ungodly sound. It pulverized and collapsed buldings and human beings caught in its fire were crushed to death in an instant. This weapon seems to be a single prototype as none were found anywhere else. The SS also sealed the Jews in the sewers and then pumped toxic gases into them to kill them as well.
