What’s special about this coke-dispenser?

1.

• The "Coca-Cola Space Dispenser" (Fluids Generic BioprocessingApparatus-1, or FGBA-1) was designed to provide astronauts the opportunity to enjoy Coca-Cola and Diet Coke in the weightless environment of space, and to "provide baseline data on changes in astronauts' taste perception of beverages consumed in microgravity." It held 1.65 liters each of Coca-Cola and Diet Coke. An astronaut would dispense the carbonated drink of choice into a "Fluids Transfer Unit" or sealed drinking cup through a quick connect on the dispenser. To save power, the dispenser would chill the liquid on demand via cooling coils between the storage container and the quick connect fitting. The FGBA-1 and 18 of the "Fluid Transfer Units" flew aboard the Space Shuttle Discovery in 1995.
