Were it not for Reddit – and the tendency of its visitors to repost ancient video in search of sweet, sweet karma points – many of the Internet's better moments would be lost to time and the ever-shrinking collective memory of humanity. Fortunately, today brought us a bit of a Flashback Friday in the form of a gif from a 2015 video featuring astronaut Scott Kelly – who later invented water bubble space ping-pong – dissolving an effervescent tablet in a floating bubble of water on the International Space Station. Suffice it to say, it's mesmerizing... and a little disturbing, if cool. Naturally, we thought we'd give you the full video here.




A comment thoughtfully added by Redditor "ryuurhal," links to an archived NASA page intended for science educators and their students that explains some of the science of carbonation in space.


"The bubbles of carbon dioxide in carbonated beverages aren't buoyant in a weightless environment," the article states, "so they remain randomly distributed throughout the fluid, even after swallowing. This means that carbonated beverages including soft drinks and beer may become a foamy mess during space travel."


No beer aboard the ISS? That's probably for the best, though it does open the door to the utility hard liquor.
