This week's LEGO Build Lab features a special Tactical Tech Challenge. Coordinate, plan, and construct a complex, weight-bearing (books, obviously) bridge within the time limit and gain a practical feel for the logistical and structural engineering feats military personnel accomplish in the field. We invite local veteran engineers, mechanics, and technicians to speak about how their military training translated into incredible engineering careers, and have them judge the teen builds. This class is part of the 2026 Maryland STEM Festival. Click here for the full schedule of classes and events for all ages.
