Optiko allows children to play with light colors, color blends and shadows by means of light experiments. The experiment box contains 23 interesting experiments, from the mixing of light colors or the propagation of light beams up to the creation of moving pictures in a trick film.
However, we perceive the light very well when it comes into contact with shadows. The interplay of light and shadow holds a strong fascination in itself, since it exerts a special charm on us. Shadows occur everywhere in our environment or in everyday life. Not only the sun, but also the moon or the lightning of a thunderstorm can produce a visible shadow. Also artificial light sources, such as candles or electric incandescent lamps project well visible shadows.
