I just was watching an episode of MythBusters on DVD (1st season). These Mythbuster guys are a hard group to get by and the episode tried to bust the myth of the toilet flush contaminating toothbrushes, etc. They couldn't bust the myth. Conclusion is that there is a "spray" that leaves the toilet bowl spreading fecal matter and germs everywhere. The contamination even settles on things outside the bathroom.
Now I'm sold on this invention selling big time. I'm first in line.
