In 1985, four cans each of Coke and Pepsi launched into space aboard the shuttle Challenger as the soda rivals tested drinks for microgravity. Both companies designed special 12-ounce cans that astronauts could use in orbit. Coke's space-can technology cost about $250,000, while Pepsi's version also used a 12-ounce can but reportedly cost $14 million.
