IC 418 spans 0.3 light-years across. IC 418 IC 418, also known as Spirograph Nebula, is a planetary nebula in the Milky Way Galaxy. The name derives from the intricate pattern of the nebula, which resembles a pattern which can be created using the Spirograph, a toy that produces geometric patterns (specifically, hypotrochoids and epitrochoids) on paper. Only a few million years ago, IC 418 was probably a common red giant star. Since running out of nuclear fuel, though, the outer envelope has begun expanding outward leaving a hot remnant core destined to become a white dwarf star. IC 418 lies about
Spacewarp (toy) 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. Production of Spacewarp toys ended around 1988. Replacement parts were sold until 1995. A redesigned Spacewarp
