How It Is Used
Looking through the eyepiece while turning the end-cap moves the coloured pieces, and the angled mirrors reflect them again and again into a symmetrical pattern that changes with every turn. It gives young students a hands-on way to explore multiple reflection, symmetry and colour.
Frequently Asked Questions
How does the Kaleidoscope make its patterns?
Three or more mirrors, typically set at 60° to form a triangle, reflect the loose coloured pieces many times over. The result is a symmetrical hexagonal or circular pattern that changes as the end-cap is turned.
