For a family gift exchange game, I am giving a gift of the form: "25 dollars will be donated to a charity of you choice from this list"

Please help me form that list. My goal is to make the list feel as diverse as possible, so it feels like there is a meaningful decision, without sacrificing very much effectiveness.

My current plan is to take the 8 charities on givewell's top charities list, and remove a couple that have the same missions as other charities on the list. Maybe adding MIRI or other Xrisk charities (give me ideas) that are very difficult to compare effectiveness with the givewell charities.

What would you put on the list?
