The document provides instructions to make a kaleidoscope using mirrors, cardboard, transparent paper, tape, and colorful paper. The first step is to tape mirrors together to form a triangular prism. The second step is to bend cardboard into a tube to hold the prism. The third step is to tape transparent paper to the bottom of the tube. Colorful paper pieces are added to the prism inside the tube to create images through reflection when shaken.
