Not all NASA gigs involve rockets and spacesuits. Zero-G motion sickness is a common problem for astronauts, and someone has to test the bags o' biliousness. Meet those intrepid scientists who make NASA's fake vomit.

Here's the description of the video from NASA's Youtube channel:

After answering the question of how the space potty works, astronaut Mike Massimino now visits the Advanced Water Recovery Systems Development Facility at NASA's Johnson Space Center. Chemists have been working hard to develop a next-generation trash bag for future exploration, including testing different forms of trash...and fake vomit.

And in case you missed it, here's the video of Massimino investigating the space toilet:

Mike Massimino helps answer the one question he and other astronauts get asked most often: "How do you 'go' in space?" Mike catches up with STS-132 Mission Specialists Steve Bowen and Piers Sellers as they get some "refreshers" on the use of shuttle Atlantis' "Space Potty." (Training includes an "alignment camera.")
