Be warned—the Spacewarp 5000 isn’t for the faint of heart. You actually have to cut the tracks and create a perfect fit or your ball will go flying into oblivion (or at least across the room.) On the website it also says that the instructions are in Japanese but don’t worry as the kit comes with step-by-step picture instructions that, in my opinion, usually end up being easier to understand than the written ones anyway.

“The classic Spacewarp toy from the 80’s has been recreated in Japan and imported by ThinkGeek for your rolling pleasure. What is it that fascinates us about rolling steel balls on a roller coaster style track? Perhaps it’s the mesmerizing perpetual motion as the balls zoom around loops and curves, only to be cranked corkscrew style up to the top for another go-round. Or maybe it’s the hours of assembly time spent tweaking each section of track to get the perfect run without the balls flying across the room. Either way, the Spacewarp 5000’s appeal is half geek based construction project and half satisfaction of watching your intricate marble coaster in action. Of course you can build the exact structure shown here, or design your own crazy track with only the laws of physics as your limitation.”
