We worked with some kids in Nevada on a water filtration project, to try and clean up our used dishwater so it can be used again. They sent us a video of one of their solutions that worked for them, and we replicated it here on Mars*. We made a video of our work on it, and sent it back to the kids. Check out our video here:
Thanks to Neil for the recording, and Sophie for putting it all together. We of course took it a step further and built our own “spectrophotometer”, as Sophie was calling it, to measure the opacity of the filtered water.
