Grades one and up. The "sunlight" shines onto the 9 planets as they orbit all around it. The central tower and planetary assist rods are black so that they "vanish" in a darkened room for a stunning result! Exchange the photo voltaic dome with the star dome to develop a stunning planetarium sky full with significant constellation names. In addition, the foundation features a special 1000-hour light bulb and planetary longitude marks so the planets can be set up to their appropriate positions. The Solar Technique model is powered either by four C batteries (not included) or by an optional AC adapter (not included).
