Question

Project:make a kaleidoscope and make a presentation in the class about how it works

Answer 1

take three equal sized rectangular mirrors and attach them to edge of another using tape to make a triangle. take a plastic pouch and add in colourful beads and attach it to one end of the triangle. you can cover this with a cardboard tube and decorate it and cover the other end with a cardboard circle. make a hole in middle of circle to see. see through the circle and as you rotate the kaleidoscope you'll see beautiful patterns.

this is because the triangles reflect the images of beads and form a beautiful pattern.
