I need ideas for a HIGH SCHOOL carnival.?

Question

I am in charge of planning our school's carnival to "send off" our senior class. All of the ideas and planning lists that I've seen online have been for a younger demographic. This year we are on a tighter budget for this event, and I need ideas for cheap, easy, and FUN activities for high school students. Thank You!

Answer 1

A dunk tank will bring in LOTS of money especially if you can get a teacher or the principal to sit in it.  You'd have a long line waiting for that.

What do you think of karaoke?  

What about a dance contest?  Winners chosen by applause.

The prize would be a CD of the song they danced to.

Answer 2

DUNK TANK

Their are between $100 and $200 to rent per day. Charge $1 for three balls and you have you money back in no time.

Answer 3

Whipped cream pie throwing.

Water games.
