Ahh yes Windy the W7 MessFind...That was an ultra top secret design for disposal of "waste materials" in the International Space Stations toilet system, unfortunately it turned out to be a load of unworkable crap after "waste" ended up being shot out and sticking onto the ISS ceiling!! ..
NASA pleaded with me to come up with one of my own trusted and tested devices, iam already working on it..
Now, that was just that the W7 MessFind wasn't ready for weightlessness....And NASA never quite forgave me that stain.
Neither did the technician whom was using the facilities at the time....Butt, that's another matter entirely. (cough)
How's that TF approved Alien Proof Aluminium Plunger coming along?
