In 1984, researchers for Coca Cola had an idea about dispensing carbonated beverages in space to give astronauts more choices to drink and also to create a stellar advertising opportunity. The company developed a can that would work in weightlessness to keep the cola fizzy without spewing out of the can. NASA agreed to let the astronauts try the Coke device on a Shuttle flight. When Pepsi learned of this project, it also wanted to participate and developed its own container. Both Coke and Pepsi products were flown on the STS 51-F mission in 1985 so crew members could evaluate the dispensers and do a taste test. Results were mixed and NASA did not add either company's product to the Shuttle food pantry; the mid-1980s "Cola Wars" continued on earth but not in space. NASA gave the Museum this extra Pepsi can that was modified for spaceflight.
