Yes, science is also funny!
What you see in the videos below is not exactly a scientific experiment.
It’s more like a moment of relaxation, a fun time between the daily activities on International Space Station.
The astronaut Terry Virts inserts an effervescent tablet into a ball of water while crewmates filmed the reaction with the Red Epic Dragon, a camera capable of recording four times the resolution of normal high-definition cameras.
In the second video, Scott Kelly release the water from a container and colors it of blue, red and green.
Then insert the effervescent tablet that makes it vibrant and observes how the gases are released outside.
The images are captured with the same HD camera.
The RED Epic Dragon Camera
The Epic Dragon camera by RED, a digital cinema company, is capable of shooting at resolutions ranging from conventional HDTV up to 6K, specifically 6144 x 3160 pixels.
By comparison, the average HD consumer television displays up to 1920 x 1080 pixels of resolution, and digital cinemas typically project 2,000 to 4,000.
The RED camera used on ISS is the same model used to record theatrical releases such as The Hobbit trilogy and television programs.
