Catch a little piece of rainbow with the Kraul Small Acrylic Prism, a beautifully simple introduction to light, colour and the fascinating science of optics.
Place the clear prism in a beam of sunlight and watch as white light is refracted and separated into its spectrum of colours, casting a tiny rainbow across the room. Move the prism, change its angle or follow the sunlight through the day and the rainbow moves with it, turning a simple observation into an invitation to experiment.
Children can also look through the prism and notice delicate bands of colour appearing where light and dark areas meet. It is a wonderfully immediate way to begin exploring refraction, the colour spectrum and how light behaves, without complicated equipment or instructions. Kraul calls its family of prisms A Piece of Rainbow, a name that captures the magic of this deceptively simple experiment beautifully.
Made from clear acrylic, the small prism is light and robust enough for repeated experimenting. Its compact size makes it lovely for a sunny windowsill, nature or science table, home education space or classroom, and it is just as captivating for adults as it is for children.
A little object with a remarkable effect, and a perfect example of Kraul’s philosophy of helping children understand the natural world by observing and discovering it for themselves.

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 roots stretch back to the 1920s. Its toys grew from a combination of Waldorf education, science and a deep connection with the natural world, creating playthings that encourage children to experience ideas rather than simply being told how they work.
