Additional details

From the desk of the product designer:

Behind the design

The downward slope leading up to the loop in the Loop-the-Loop build was inspired by the Brachistochrone Curve – meaning that the marble picks up more speed faster to complete the loop and continue on the track!

    This was fun to build. My grandson built 95% of it by himself.

    Great for all ages learning engineering/physics/robotics/“Rube Goldberg” concepts and to engage students who crave hands-on activities.

    He absolutely loved it and so did him mom. The plastic tracks and the noise the marble makes are very soothing to millennial ears. It brings back memories!

    I saw a picture of one of grandsons looking at it. Their father seems happy
