Review on Marble Genius Pipes Sphere Attachment by Jamonte Hamilton
Poor Design Best in Marble Runs
This toy has a set of balls and tubes. The tubes must connect the balls. However, the pipes do not sit correctly in all areas. Only the yellow "end" balls have the correct size holes for tubing. In all other areas there are two design flaws: 1) The holes are too small to fit the tube, forcing a bend at the end of the tube. 2) Insufficient clearance within the ball to prevent the tube from being inserted far enough to engage. The combination of these two problems results in loose connections and ball sticking.
