The New England Sci-Tech (NEST) STEM education center , in conjunction with JP Rocketeers and Sci-Tech Rocketeers, will host an Introduction to Model Rocketry and Demo Launch on October 21, 3:30-5:30PM, at 341 School Street in Acton. It’s for those who have had little or no exposure to model rocketry, or those who have some experience but seek guidance and information about how to progress as a model rocketeer. Weather permitting, they will launch rockets in a variety of sizes and designs. They will discuss design, materials for construction, preparations for launch, and safety. Email David at muse3@comcast.net to RSVP or to get more information.
