A topic of interest for the Nazi party was the ability to make sea water drinkable. Due to naval warfare's tendency to leave sailors offshore in ships for long stretches at a time, being able to drink the water around them would allow for lengthier trips at sea. For the sea water desalinization experiment there were 44 subjects, primarily made up of European Gypsies, that were placed into four different testing groups that could only drink one type of water. The groups were made up of sea water, sea water processed by the 'Burka' method, sea water without salt, and no water at all. The horrific experiment was made even worse by the fact that each victim was punctured in their liver or spinal cord for data gathering purposes, and they were not allowed any food or other rations during the testing. Most victims that were made to drink sea water died, following tortuous convulsions and diarrhea, hallucinations and madness.
