What should we do for a fundraiser?

My best friend and I have a relay for life team and we're looking for ideas for our big fundraiser. We've talked to our princepal and she said we could use the school. The only thing she said we can't do is have a dance because the school has had too many this year. Another teacher at our school who has a team is doing a talent show so we can't do that.

Any ideas on what we can do?
