Microgravity
The lack of normal convection in microgravity is demonstrated by a carbonated soft drink floating in the middeck of the Space Shuttle. While the droplet is oscillating slightly and starting to assume a spherical shape, it is filled with carbon dioxide bubbles in a range of sizes. On Earth, the bubbles would quickly foat up to form a head. In space, they are suspended. They may drift with time and eventually the surface tension between individual bubbles breaks, allowing larger bubbles to form. This image was taken during STS-51F mission (Spacelab 2) which carried test models of dispensers from two pupular soft drink manufacturers. Photo credit: NASA/Johnson Space Center (JSC)
