This is the mesmerizing moment astronauts showed how dissolving an effervescent tablet in water in space creates a floating mass of bubbles. Scientists on board the International Space Station carried out the experiment by using an alka seltzer-type tablet, water and some food dye. At first the soluble tablet is inserted into a floating globe of water and astronauts look on as it moves around in the air. Scroll down for video

After watching the tablet start to effervesce, one astronaut fills the bubble with with coloured food dye
An astronaut then adds food dye, turning the clear ball a blue colour before adding a red dye, which turns it bright green. It then continues to expand as the effervescence causes the escaping gas to fire out in all directions.
The mesmerising images were captured on NASA's brand new RED Epic Dragon camera capable of capturing resolutions up to 4K, four times the resolution of normal HD cameras. The camera can also record at up to 300 frames per second, making it ideal for capturing fast moving events.
After adding the dye the ball turns bright blue as it floats around in space, with the images being captured on new Nasa cameras In practice it is likely to be used to film events like vehicle docking and undocking to the station and provide additional data in scientific work on the space station. It can also reveal more information when used to film scientific investigations, giving researchers a valuable new tool aboard the space station. The cameras are currently being evaluated for captuting science data and vehicle operations by engineers at NASA's Marshall Space Flight Center in Huntsville, Alabama.
More food colouring is added turning the floating ball of bubbles a shade of dark green as the tablet continues to disolve
It then continues to expand as the effervescence causes the escaping gas to fire out in all directions Nasa said it also hopes to deliver more ultra-high resolution footage from inside and outside the space station in the future for members of the public with televisions or computer screens capable of viewing them. The camera could provide some of the most detailed images yet of our planet from orbit. However, astronauts don't usually allow liquids to float around the space station to prevent any damage to delicate equipment. Instead they have specially adapted tubes which allows them to drink without liquids floating around.
