Somewhere in this marble run is a 5-marble tower launcher. The marbles are numbered 1 through 5. Before you watch the marble run, submit a guess in the comments below about the order you think they will be launched, and then watch to see if you were correct! The launch order could be 42351, 52134, 12345, or 117 other possibilities!

This marble run took 16 days to create, including several full days of troubleshooting and redesigning. After around 80 attempts at filming the track, I had to stop. I had become so utterly frustrated with the poor fit of the pieces and the inconsistent operation of GraviTrax action tiles that I considered giving up the GraviTrax hobby entirely. I had to use wall mounting putty in many places to stick pieces solidly together so that an action tile's momentum would be transferred to the marble rather than into unwanted movement of the tile. Given the high price of GraviTrax sets, the parts should click nicely together like Lego bricks. Ravensburger needs to improve its engineering design and production, because this frustration takes the the fun out of building large GraviTrax marble runs. The challenge should be about solving physics challenges, not challenges resulting from inconsistent fit and operation. In the end, the marble run would not run completely from beginning to end, and so this is NOT a GraviTrax world record for the longest lasting marble run. The longest segment I was able to film lasted less than 11 minutes.

Thank you to everyone who submitted their great track ideas for this marble run build. These tracks were modified for greater reliability and longer runtime, so they do not appear exactly as submitted. If your track was not included, it was either because I ran out of space, or because the track didn't work well in real life.
