In this video we'll try to break these records:
🌎 The longest GraviTrax track ever built
🌎 The longest (distance) marble run on a GraviTrax track

📅 The GraviTrax Building Event:
On May 7, 2022, a group of over 40 people assembled a continuous GraviTrax track that was 1/8th of a mile long, over 200 meters! The track was built of 100% genuine Ravensburger GraviTrax pieces. This broke the previous record of longest GraviTrax-compatible track (50m) held by Eric M. GraviTrax (https://youtu.be/m4RuVlJcGJI). Compounding the difficulty of our task, our record-breaking GraviTrax track was built outdoors on a sidewalk. The marbles had to contend with headwinds, trees dropping their spring blooms on the track, and a sideways-sloping and sometimes uneven sidewalk.

🟢 The Marble Run:
Once complete, we ran marbles on the track in an attempt to achieve the world's longest run on a GraviTrax track. Though we didn't get a run of 1/8th of a mile, we did set the world record. See how far we got!

🙏🏻 Thanks:
A hearty thanks to everyone who participated in this epic GraviTrax marble run build! I have tried to list everyone in the video credits, but if I missed your name, please forgive me.

🏘️ LACR HOA:
Thanks to the Lakes at Castle Rock Homeowner's Association for providing their permission and traffic cones for the event.

⚙️ How it Works:
GraviTrax marble runs are powered by gravity. The marbles gain speed from the tilt of the GraviTrax track relative to the earth's gravitational field, and from GraviTrax action tiles like the Scoop, the Hammer, and the Magnetic Cannon. It is ultimately the angle of the surfaces on which the marbles roll that powers GraviTrax marble runs. Height tiles are combined with baseplates to set the final height adjustment, giving the track an angle, making the marbles roll.

🔗 Here are some links to the designs we used in the track, and the planning to make it to 1/8th of a mile. Most of the designs were based on the limits of my GraviTrax inventory. For example, we had to build using curves in the first part of the track, because I didn't have enough junction tiles and 3-way-merge tiles.
