Race to the finish line "flying" on a broomstick.
brooms
obstacle course (optional)
Using brooms, guests "fly" (holding them as if they are flying on them) and run down to the finish line.
Another cool one is to have an obstacle course, where they have to hold the broom and actually throw a ball throw a hoop or two� not quite like below, but you can always call this Quidditch practice or something.
