5. Close the viewing end. Cover one end of your tube with a disc of cardboard with a viewing hole cut in the center. Secure this with glue. Slip the mirror tunnel inside your tube. Gently pack it in place with foam rubber or something like it. Make a long, equilateral triangular tunnel of the mirror strips---mirror surface facing the INSIDE of the tunnel. Secure the mirror tunnel by wrapping duct tape (or something similar) around the outside.

6. Fill and close the object chamber. Find some colorful beads, bits of colored glass, costume jewelry "gems", marbles or whatever. These should be small, brightly colored and transparent. Put them in the cup (object chamber) but don't overfill.. There should be room for the objects to tumble around and form changing patterns. Glue the other transparent disk on top to close the chamber. Now make your object chamber. Cut two disks of transparent material (glass, Lucite, Lexan, etc) to match the diameter of your tube. Next, cut a one-inch strip of lightweight cardboard a little longer than the circumference of your tube and curl it around, gluing the ends, to make a circle that matches the diameter of your tube.Let the glue set up. Now glue this to one of the transparent circles to make a little cup. Let that glue set up.
