Immediately after WWII, during the Soviet-era, scientists created astimulant which they believed wouldenable soldiers to not require sleep for two weeks or more. They decided totest their new gas on a few prisoners; promising them their freedom upon completion of the experiment. They locked the men in a hermetically sealedchamber and began pumping in the gas. Within a few days, the men were exhibiting the kind of paranoia and psychosis that is a typical symptom of sleep deprivation. But as time went on,they began to act even more strangely. One of the men even brutally pulls out his own eyes, yet remains alive. Five days into the experiment, when scientists could no longer see the menthrough the thick glass of the chamber,or hear them through the microphones, they fill the room with fresh air and unlock it. There, they discovered that one of the men was dead, and the surviving test subjects were allsporting horrendously violent injuries, some of which appeared to be self-inflicted. It was clear that the deadman had been a victim of cannibalism. The fate of the emaciated survivingtest subjects was death. The experimentwas deemed a success.
