Overview
A school-age builder snaps together tracks, bridges and base plates, then watches balls roll through curves, junctions, a vortex and a magnetic cannon. Example tracks and instructions are included to start.
Kids who like experiments get a flexible marble run that teaches gravity through trial and error, with room to grow through other lines in the system. The part count is quoted two ways, so buyers should treat it as approximate.
Who it's for
Children, teens and adults who enjoy designing their own marble courses will use the tiles, switches and cannon. Younger children, or anyone expecting a ready-built track, should choose another toy.
Pros and cons

Performance notes
Balls roll by gravity along tracks, and the junctions, switches and vortex change their path. Layouts built on the base plates and levels decide how fast and how far a ball travels. Exploring that rolling behavior is the learning goal the maker describes.
