Awesome, bet the girls had fun. My dad and I did a tag team 2 night event with my niece's girl scout group (this was several years ago and there wasn't an opportunity to work flying in). My dad did a telescope / stargazing night. I came in and talked about rockets and space travel. I spent days trying to come up with a fun and effective way of demonstrating how hard it is to get to the moon. Finally I came up with having one girl be earth, and spin around, and have a second girl run around the earth girl. I gave earth a soft ball (spaceship) and told her she had to hit the moon with it. I thought no way she'll get it on the first try. But I was wrong, still illustrated the point fairly well though.
