This DIY kit allows you to construct viewing glasses using various optical lenses and mirrors, with which you can simulate the vision of different animals: insects (kaleidoscopic vision), animals with eyes on top of their heads such as stingrays (upward vision), birds such as eagles (downward vision) and fish (vision from two sides simultaneously). The set contains all necessary optical components and parts for constructing functional viewing glasses. The high-quality lenses and precisely manufactured mirrors enable a clear and distortion-free representation of the different visual perspectives. Through practical application, you learn how optical systems work and can experience firsthand how the visual field of various animal species feels. A fascinating experiment that combines biology and optics in a vivid way. Dimensions (L × W × H): 20.0 × 40.0 × 5.0 cm Age recommendation: 12 years and up

This creative wooden kaleidoscope DIY kit with four different object chambers invites playful exploration of the seasons. The high-quality wood design combines crafting fun with fascinating optics and offers ever-new visual surprises through the interchangeable chambers. A perfect DIY project that promotes manual skills while awakening fascination for optical phenomena. The natural wood surface feels pleasant in hand and gives the self-built kaleidoscope a special charm. Each of the four object chambers is thematically dedicated to a season and contains appropriately selected materials that are combined through multiple reflections into ever-new kaleidoscopic patterns when turned and moved. Assembly is achieved through a well-thought-out plug system that requires no complicated tools. After completion, a functional kaleidoscope emerges that offers four different optical experiences through changing the object chambers, providing variety and discovery joy for a long time. Dimensions (L × W): 17.0 × 8.5 cm Age recommendation: 5 years and up
