Once they learned and practiced the routine, we blasted the Darth Vadar music and I rushed the kids to a hiding place. Then, Darth Vadar (aka Dad) marched out and challenged all the kids. He wanted them to join the dark side and they all screamed "never!" We had each kid go through the routine they had learned and 'fight' Darth Vadar. They all got their own mini light sabers that glowed and we played a game where we dropped meteors from the 2nd floor and they had to pop a 'meteror.'
