Fluid magic: What happens when you mix water, effervescence and paint in space? (VIDEO)
The experiments carried out aboard the International Space Station (ISS) were not strictly scientific, however, but also a bit of entertainment. The latest footage – one of the first of its kind – has recently been released by NASA’s Johnson Center, and shows how peculiar merely coloring water turns out to be aboard the ISS.
It was shot with a RED 4K camera that NASA engineers at the Marshall Space Flight Center in Huntsville, Alabama are evaluating for use in capturing science data and footage of vehicle operations.
In zero gravity, NASA astronaut Scott Kelly made floating blobs of water and then turned them various colors – blue, red or green – by injecting dye into them. Once colored, the levitating balls of liquid also got to swallow effervescent tablets, causing them to burble and spit.
