I'm going to be doing a puppet skit with four volunteers: two kids and two adults. There will be quite a bit of moving. The act calls for some of the puppets to be moving left to right at one point. The height difference may be a bit of an issue for the kids. Any ideas? Recasting the kids with adults is not an option. Part of the reason I'm doing this skit is to help increase involvement. I'm also thinking of building a height-adjustable stage so that the performers can sit down during some of the skits. (Only one skit requires them to move around.) I was thinking to building the stage with some PVC pipes and fittings... but if anyone has any better ideas I'm open to hear them.
