This unique device allows you to demonstrate how the Sun shines on the Earth at different angles during the year. Simply place any globe up to 35 cm in diameter on the rotating base. A vertical arm with adjustable holder supports the flashlight provided at the correct angle. The base is marked in 365 day increments to permit an accurate representation of the winter and summer solstices and the vernal and autumnal equinoxes. (Please note: A globe is not included.)
