NASA released today more 4K Ultra High-Definition (UHD) video footage captured by the space station's RED Epic Dragon camera — and it looks like the astronauts are having a lot of fun playing with their new expensive toy. A clip posted to the ReelNASA YouTube channel shows Astronaut Terry Virts — who was on the ISS from November 2014 to June of this year — insert an effervescent tablet into a floating ball of water.

The tablet fizzes and dissolves inside the watery orb at a resolution of 3840 x 2160 pixels. Although the RED camera can also record in 6K — capturing a resolution of 6144 x 3160 pixels — YouTube only supports 4K video at the present. (Besides, there aren't that many 6K monitors out there.)

The RED Epic Dragon camera launched to the station aboard a Falcon 9 rocket in January, as part of SpaceX's fifth commercial resupply mission for NASA. In June the space agency announced it would start posting 4K videos from the camera to YouTube, to capitalize on the site's new ability to play UHD videos at 60 frames per second. NASA says it will try to post new videos to its YouTube channel every few weeks.

Watch Virts' zero-G science experiment in the video above, set to a soundtrack that's like the elevator version of EDM.

Correction: The resolution of the video on YouTube is 3840 x 2160 pixels. A previous version of this story said it was 1920 x 1080 pixels.
