I've seen the show twice and they didn't throw snowballs at the audience either time, so perhaps the video was from opening night or some other occasion. However, there are two scenes in the show when Phil interacts with other characters and they throw snowballs at unseen people offstage (to stage right). The "snow" sprinkles from overhead onto a specific area of the stage and they get down on the ground and pack it into balls and throw it. It appears to be a synthetic substance than wafts down lightly and packs well.
