    A group of 18 students between ages 8-11 built bridges made of K’Nex rods and connectors Saturday at the Mountlake Terrace Library.

    The class was part of “Science Saturday with the Pacific Science Center,” which is held twice a month at the library.

    The budding engineers were asked to design and build bridges, keeping structure and aesthetics in mind. A spring-loaded tool then stress-tested the bridges for strength. Inevitably, the bridges would collapse under the heavy load.

    It was then up to the students to rebuild the bridges, using greater reinforcement.

    The Friends of the Mountlake Terrace Library and Sno-Isle Library Foundation sponsored the class.

    Future Science Saturday classes are:
    The Sciences of Art, Dec 12, 1:30-3:30 p.m.
    Unravel the Mysteries of Light, Dec 19, 1:30 p.m.
