Help with Streaming For Cancer Research

Hey guys, Our fraternity at Drexel University raises money every year for the St. Baldrick's foundation which funds children's cancer research. A fundraising idea we had was to do a 24 hour stream to raise money. This would include mystery skin giveaways, donations for team comps/matchups, a 3v3 tournament, and some other potential ideas. What would you guys suggest or like to see in a stream like this? We're trying to raise a couple hundred dollars for the foundation and all feedback is welcome and appreciated.
