While these astronauts where at the International Space Station, they took the time to shoot a 4K video of an effervescent tablet dissolving in a floating ball of water. Why? Because they can. NASA put up this video as an example of the detail they can capture now, which could lead to amazing astronomical photos.
Hopefully these astronauts don’t get a tummy ache any time soon, because it looks like they’re using all their Alka-Seltzer tablets to make awesome vids in zero gravity.
