The student paper linked to seems to mainly be supported by the work of Charles Gerba. The student paper references
this story, where Gerba is quoted as saying:
Quote:

Toilets have an aerosol effect that remains widely unrecognized. "Droplets are going all over the place -- it's like the Fourth of July. One way to see this is to put a dye in the toilet, flush it, and then hold a piece of paper over it. You'll get what we call a commode-o-graph. Every toilet has a characteristic ... well, that's a whole other story."

Well, I went to Wal-Mart tonight and bought a $1 bottle of red food coloring. After putting much much more than was neccessary in my toilet, I held a blank piece of printer paper directly over the toilet (about 1/2 inch above the seat). After flushing the toilet, the paper turned out to be completely blank.
So, it did not work for me.
(edit:
I forgot to mention -- I stirred the toilet water up with an unused drinking straw, so as to mix and distribute the red dye evenly)
