The KidzLabs Solar System Planetarium is a complete build-and-paint kit that lets children assemble a glow-in-the-dark model of the solar system. Plastic planets snap together without glue, attaching to a stand with rotating arms embossed with the distance from the sun for each planet. Once assembled, the 11.8-inch model can be painted with the included paint strip and glow paint, creating highlights that glow in the dark after being charged under light.
