any of you people who are AMAZED by this project could build the same thing very easily if you had the same parts. i guarantee it. bending the bendable tracks and connecting them together with the little plastic connectors is not rocket science. lazily using a million booster stations to keep the momentum going does not require a high school physics class.

or maybe one day you'll discover the far more interesting rube goldberg machines on youtube, etc. here's hoping you manage it, anyway... :)
