How did she stick the pages of the burn book up??

[AloeVeraLynn]

I don't know why it popped into my head today but I'm wondering...
In Mean Girls when she prints the pages of the burn book and posts them around the school, how did they stick?! It was just a pile of paper and she slapped them around the place.
Indulge me.

Sticky notice boards? We have one at work.

I always wondered this! Also always wondered how Cady got blamed for most of it when she was a new student and would have no way of knowing some of the stuff (let alone the people) in the book and the handwriting would have all been different.
