When astronauts visit schools, they are inevitably asked about the bathrooms in space. So, when I did an hour-long Zoom with Woody Hoberg up in the ISS, as we explored the station, we had to make a pit stop — you can jump to that part of the full video.
The Russian toilet they all use is even more insane than I imagined. I knew about the “technique” required, but I did not appreciate the stockpile of waste-filled metal canisters filling up one of the Russian modules awaiting disposal by Cygnus. It’s like having a metal diaper genie and throwing the whole heavy unit away when it fills.


Those filled metal canisters for as far as the eye can see are awaiting disposal by this Cygnus "trash can" that burns up on reentry.
