Supergirl Birthday Party Ideas?

you'll need several toy cars.
choose two teams.
this is like a relay race, the first person in line on each team takes a toy car and holds it between her knees and has to "carry" it that way down to a small box or basket (that you could stand over with something between your knees) and the car has to be dropped in the container. if the car is dropped or misses the container that person has to go to the end of the line and try again.
the team with the most cars at the end (time depends on how much fun they are having) wins!
only super girls could carry cars between their knees!
