The Kraul Triangular Glass Prism is a beautifully crafted optical prism which invites children to discover the science of light. As sunlight passes through the glass, white light bends and separates into a glorious rainbow spectrum — a simple, hands-on moment that brings the wonders of optics and colour to life. Hold it up to the light or rest it on a sunny windowsill and let the colours appear. Whether used for homeschooling, science projects, or simply to satisfy a curious young mind, this prism is a gently captivating STEM learning tool that inspires genuine scientific curiosity through open-ended exploration. Why We Love It Made from high-quality glass, this is a prism that feels substantial and special — a world away from plastic alternatives, and something a child might treasure for years to come. It comes with a small wooden display stand, making it easy to position on a windowsill and let the rainbow do the work — no hands required. The way science and beauty meet here is really something. Watching white light split into a full spectrum is the kind of moment that makes a child stop and ask "but how?" — and that curiosity is everything.
