What makes a rocket work? How can it go so fast? We’ll build and launch our own rockets to help us answer these questions. (To keep it safe, the rockets will be powered by compressed air and run along a special rocket track set up indoors.) We’ll talk about thrust, inertia and drag, and then choose a rocket sled plan we think will go the fastest. A high-speed camera will record the results. Hosted by Val Germann and cosponsored by the Central Missouri Astronomical Association. Ages 9-12. Registration begins Tuesday, July 15.
