We have had a goal for a while to build a tall Marble Run with our Marble Genius Marble Run Toys and we decided to do just that a couple weeks ago. After establishing a solid base with 10 bases, we started inter-locking the Marble Run pieces. Building the first 6 feet of the Marble Run went relatively quickly because a ladder wasn't necessary. The base and the first several feet of the Marble Run were the most important because the strong foundation we established allowed the Marble Run to climb over 2 stories. In addition to the large number of bases at the bottom, 4 "poles" were established that would extend from the bases to the very top of the Marble Run. You can see these 4 "poles" that are a combination of Marble Run Tubes and Marble Run Action Pieces in the main picture.
Once we got above 6 feet, a ladder was necessary to complete the build. This is the part of the Marble Run that took the most time (over 3.5 hours). All told, it took over 5 hours to build this 2-Story marble Run and took over 20 Marble Genius Marble Run Toys (Starter Set, Super Set, & Extreme Set). As we were finishing, the wind started to pick-up so it became necessary to secure the Marble Run to the ladder with a couple of bungee cords and we secured the ladder to the roof with a bungee cord as well. This allowed us to keep the Marble Run up for about a week so that we could produce the video below.
We occasionally see feedback on Amazon that indicates our Marble Run Toys are not very stable. We hope this 2-story Marble Run provides encouragement to those that struggle to create a stable structure. It absolutely can be done if you establish a solid foundation and interlock the structure. Please enjoy this Marble Run and we would love it if you would send the tallest Marble Run structures that you have created!
