Spacewarp (toy) Spacewarp is line of build-it-yourself, marble run toy "roller coasters" first made in the 1980s by Bandai. Users cut lengths of track to the correct size from a single roll of thick plastic tubing, forming curves and loops held in place by plastic track rail holders which attach to metal rods held vertical in a black plastic base. Steel balls roll around the track and on to a battery-powered Screw conveyor that takes them to the top to start all over again.
