If you have a teacher who is up for anything…
Choose three to five outrageous colors and find a favorite teacher willing to dye his/her hair. Have students and faculty pay to vote to change the teacher’s hair color ($1/vote). The color with the most votes is the winner and means the teacher will come to school with the new hair color! You could also consider enlisting a teacher to shave off his mustache or his/her hair altogether for a set amount (i.e. Mr. Smith will go completely bald for $500!). Partnering with a charity that accepts hair donations might be another avenue to pursue.
