WORLD'S BEST MARBLE RUN!!! (70,000 Pieces) - Marble World

This could be the BIGGEST and BEST Marble Run in the WORLD! Enjoy a tour through this INCREDIBLE creation. It took over 1 year to build and consists of around 70,000 pieces. We have never seen anything like this before. Built by Formula H67, a very talented regular viewer of my KZbin channel. I was first told about this marble run long before its release, and have been excitedly waiting to make a video to showcase it ever since. Prepare to have your mind blown!
I hope you all enjoy the video :)

This Marble run is extremely demanding, even on powerful computers. It may also take a long time to load up initially... 8m 26s for me. However if you can handle it, download it and check it out with the link above. You won't be disappointed!
