Mini Business Ideas 10 POINTS!!!?

Hi! I really need some help. In school we were asked to create a product to sell to our school. Sounded easy, Right? Wrong! I went completely blank and now neither me or my friends can think of any ideas. We are allowed to to the work in groups, like 3 maximum, and im really stuck! I would like to do something in the beauty department or something like a pamper hamper but any ideas are welcome! Ten points to whoever gives the best answer! Please help!!! Thanks!
