A simple glass sphere becomes a fascinating introduction to the science of light with the Kraul Glass Sphere.
This hollow glass ball can be partially or completely filled with water, transforming it into a lens through which children can explore magnification, refraction and the way light changes direction as it passes through different materials.
Hold it in front of an object and watch the image change. Fill it with different amounts of water and compare the results. Used underwater, with air trapped inside, the effect changes again and images can appear smaller rather than larger.
Children can experiment with distance and position, discover how a magnifying lens has a focal point and even observe images appearing upside down. What begins as an extraordinarily simple object opens up a whole world of optical discovery.
This is Kraul at its best: no complicated electronics and no unnecessary gimmicks, just a beautifully simple scientific experiment that encourages children to observe carefully, ask questions and discover how light really behaves.
Particularly lovely for home education, classroom science, STEM learning or simply for curious children who enjoy finding out how the world works.

Kraul Toys & Experiment Kits
Kraul is a family run German toy maker creating wonderfully inventive toys and experiment kits that help children discover how nature and technology really work.
Inspired by the elements of Earth, Water, Air and Fire, Kraul toys encourage children to build, observe, experiment and find things out for themselves. From working cable cars, pulleys and water wheels to optics, magnetism and outdoor experiments, each design makes scientific ideas tangible through hands on discovery.
Kraul's approach is beautifully simple: children understand scientific ideas more deeply when they can experience them for themselves. The company continues to use quality materials and manufactures and packages almost all of its range in Germany.
