Fundraiser Ideas?

Hello to all my Forest Critters viewers!  Hope you’re having a good day today!  I have a favour to ask of you all.  In my high school I'm going to start doing fundraisers soon to help raise money for my local organization that helps to spay/neuter and adopt out feral cats, "Allies for Alley Cats."  You can help me by coming up with some ideas that rowdy high school students might enjoy but are simple and cheap to achieve.  Here are some ideas I have so far and please comment if you think of anything else or have any ideas to add on or to improve my current ones.

Possible School Fundraisers

• Pet photo contest, must donate at least $1 to enter photo.  Photos will be judged, winner gets a gift card (Tim Hortons?).
• Battle of the genders, see if girls or boys can bring in more money.  Winning gender gets jolly ranchers at lunch.
• Beanie bag for a day in class.  Raffle tickets cost a) $0.50 and 5 for $2 or b) $1 each and 5 for $3 (haven't decided which price to use yet).
• Survival game in forest near school on a Friday after school.  To enter you must pay $5 at school (registration fee).  Last survivor gets a gift card (Tim Horton’s?).  After each person is caught (little flags on the belts so no one can cheat and say they weren’t caught?) they must come back and tell us so we can scratch them off the list.  Then they must continue as a predator.
