What are the 10 weirdest things ever sent into space, you ask? Ranker has the list ... and coming in at number 7 is something quite scary:
In September 2006, a space shuttle blasted off from NASA’s Kennedy Space Center with tubes containing Salmonella typhimurium to see how space travel affected germs.
Upon return, after feeding the space germs to mice, scientists found that the microbes turned into super-bugs and became stronger and more deadly than ever. The mice were more likely to get sick and died quicker than others that were fed the identical germs that remained on Earth. They discovered that the genetic behavior had altered and became three times more potent. They were also more virulent and resistant to high temperatures, acidic conditions and white blood cells.
