With different light experiments the Optiko Box allows children to get a playful access to light, colour mixtures and shadows. The Optiko Box contains 23 interesting experiments, including the mixing of light colours, the dispersion of light beams and generating moving pictures for an animation. In combination with shadows we better notice the existence of light. Especially the interplay of light and shadow offers a strong fascination. Measures 53cmL x 27cmD x 12cmH. Ages 4yrs +.
