I'm not really a roller coaster rider. Why? Because of this thing. Or, rather, because of the full-scale real roller coaster this model is based on. Sometime in the mid 1980s, (I'm not exactly sure when, because neither he or I fully remember) I talked my father into taking me on the Screamroller, a corkscrew roller coaster at Worlds of Fun in Kansas City. I do not know how old I was at the time, except, to say, far too young. (This roller coaster was disassembled and replaced with a different ride when I was 7, so I know it was before that.) I don't remember the ride itself—just standing in line being excited beforehand, and crying unconsolably afterwards.
But now, thanks to the artistry and skill of the model builder behind ModelCoasters.com, I can relive the experience, in a far less terrifying and far more enjoyably geeky way. I kind of adore model trains, and the model roller coasters built by modelcoasters.com scratch that itch well, using K'nex motors to haul the trains uphill and letting gravity do its job the rest of the way through the ride. This person has a full set of coaster models—called Project 31—showcasing all the roller coasters that were at Worlds of Fun in 1980. It's a nifty project and great work!
There's more photos and videos on the Model Coasters website. Below is a photo I took of the Model Coaster's version of the Orient Express (which I always loved to watch, even though I never had an interest in riding it). The entire series is on display in Kansas City's Union Station through August 11.
