Space Exploration Merit Badge session, plus high-power demonstrations of a flying saucer (artapplewhite.com) on a 38mm "G" Skidmark motor. The purple rockets are Estes Firestreak SST kits (snap-together since we only had 2 hours to do 100 launches!) from multiple educator packs. Saucer kit build, motors and launch provided by Jim Scarpine. Flying Saucer kit courtesy of Art Applewhite (artapplewhite.com)
