Ideas to keep kids busy

unknown

I love pinterest and doing things outside with my kids. I have a 10 year old, 4 year old (not mine but have custody), and a recently 2 year old. My best friend is having a baby Friday morning and has to stay in the hospital for four days/ three nights and I'll have her 5 and 3 year old the whole time. I need your favorite random out of the box activities to keep these kids busy!
