School sccavenger hunt???

Question

What can I do for a school scavenger hunt at lunchtime. I want it to be funny, a little embarrassing and cheeky! We r in yr 8 at an all girls school.

Answer 1

A follow-on to the previous poster's idea in making it cheeky, embarrassing and still fun, use condoms rather than balloons.  I hope that isn't too cheeky.  

You could also hide small trinkets to be found in the food, but might want to be careful with that one.

Don't limit the search to just the cafeteria.  

Answer 2

hide water balloons tied to candy

(but some water into the balloons tho. doesnt have to be much)
