How were the Jews killed in the concentration camps?

They were hung, shot, put in gas chambers, baked in ovens and starved to death.

It was horrible what they did to these poor innocent Jews. In gas chambers they were told that they were to be given showers....but instead of water coming out of the spouts gas came out and it took about 10-20 minutes for them to die. They also did labor until they died and some scientists did different "projects" on them to test their results. Usually the "patients" died a painful death.
