Alanna has an art project. With a little inspiration from Uncle Norm, she decides to make a kaleidoscope using mirrors and angles. A scientist pays a visit to the workshop to help the Rads understand just how cool kaleidoscopes really are – and how mirrors can make some really rad reflections.
The Gist: This episode is about rotational symmetry and the principles of reflection and explains why kaleidoscopes are typically constructed with 3 mirrors configured as an equilateral triangular prism to create an image that repeats one triangular pattern continuously, filling the field of view.
