Creative prank ideas?

Question

I'm a freshman girl and recently I've been playing some pranks in my art class. These pranks (things like taping a piece of paper of paper to the ceiling saying "What the h**l are you looking up here for?" and such stuff like that. Its been getting blamed on these three senior guys (I'm friends with them, and they know I'm doing it and the teacher will not believe them because I am a perfect angel in class, its first period and I'm always tired). So any ideas for our friends to get blamed for? Nothing that will be drastic enough for detentions please! (No one got detentions for anything I've done) Thank you!
