Nah, that's gross. BUT..I did create a spit ball ceiling-scape in 9th grade algebra class.
They used to give us yellow paper, and if you wrote on it with a blue pen it'd create some really snotty greenish spitballs. Good start.
Now let's work on size (yup, it does matter!)
There were a hundred spitballs on the ceiling above my desk,
all various sizes and snotty looking colors.
..also some matches I'd split them down the middle and chewed just the end and threw them up there..and those looked like whirly bird thingies...or maybe some kind of monster with long legs walking. I dont know. It was like a city scape after heaving a half dozen up there every day for a whole semester.
BUT MY MASTER PIECE, which capped my spit-ball ceiling scapist career off nicely
was a golf ball size spit ball
that took two entire pieces of math paper
and an entire 40 minutes of chewing it, to make.
I threw it up with both hands, and it made such a thud, the teacher became alarmed...but she couldn't figure it out. I was sputtering to not laugh pretty bad though. MAN! I thought that was funny at the time.
I'm still proud of it even now.
But the janitor had the total lack of appreciation to just scrape it off over summer break,
rather than take the tiles down and put them in a glass display, to show off my proud school achievement to future generations.
