What were some of the devices used in concentration camps?
If you're asking what kind of devices were used to KILL people
in the concentration camps (in Germany during WWII)... Gas chambers
were a big thing. The Nazis would make the prisoners take off all
their clothes and anything that had value. They told them they were
going to take showers, so they put them in a huge room, but when
the showers turned on, water did not come out. Gas did. Eventually
they all died. Another way they used to kill the prisoners was to
make them dig wholes in the ground then they would shoot so they
would fall straight back into the whole that they dug ... they were
basically forced to dig their own graves.
