Bring the rainbow into your house!

This extra large prism made of high-quality crown glass projects exhilaratingly beautiful spectral colours into the room.

Hang the prism in front of a window preferably facing southeast or southwest. When the low-lying sun shines through the prism, large lateral spots of spectral colours appear, which you can see particularly well when they fall into shady areas of the room. A slight rotation of the prism makes them dance in an enchanting way.

The English mathematician, physicist and philosopher Isaac Newton (1643-1727) is one of the founders of modern color theory. Prisms like these were quite common at his time as a toy, but he carried out as one of the first experiments with them which then led him to his famous and not uncontroversial theory of colours and white light.
