History <ul><li>Caleidoscope fromm greek (kalos pretty) eidos image scopeo observe. It’s a tube that has a 3 mirro, that forms a tekahedrica prism a with it reflective part inside, in one end it conteins two see thru pads wich have several colors full objects with diferent shapes. Wichs images multiples while your turns the tube and watching the other end. Those mirrors can be put in diferent angles, 45º the images multiples by eigth, 60º multiplies by six and 90º multiplies the images by four even thou the more comun has 3 mirros it can alse be build one with two or more than 3 mirros to get diferents types of effects. The modern caleidoscope was invented in 1816 by the sco9thish expert in fisics David Brewster who was the first to put it on sale. The sales were huge but it’s easy fabrication metjod let other markets copy it’s desing and states selling as imitation in a few days brewste never saw anymora incomes ans it’s one of the most fomaus toys. </li></ul>
<ul><li>Another type of Kaleidoscope it’s Teleidoscope. This is one magnifi que glass in one end this one multipliques images in it’s mirrros come from outside.. </li></ul>
How to Make? <ul><li>Remove both ends of a Pringles potato chips can or find / buy a length of PVC pipe. </li></ul><ul><li>Cut three pieces of mirror almost as long as your tube. The width of each mirror strip should be the same---and must measure LESS than the tube's diameter. Tinker with this---maybe make a cardboard model before you cut the mirror </li></ul>Here is the correct pattern of overlap for mirror strips.
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.
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.
<ul><li>When the glue has dried, attach the object chamber to the end of your tube </li></ul><ul><li>And congratulations! You've made a kaleidoscope aditionality colors.. </li></ul>
Tips <ul><li>The core from a roll of bathroom tissue is prone to collapse, apart from being too short for a good focal length---which is why we suggest alternatives. If you use the Pringles can, be careful to file off any sharp edges. </li></ul><ul><li>The transparent material need not be glass. Plastic works just as well. Plastic shops often have scraps of plastic mirror as well as the see-through stuff you'll need for the object case. Sometimes they'll cut it for you. If you're using glass and do your own cutting BE SURE TO WEAR EYE PROTECTION. Ordinary glasses or shop goggles will do. </li></ul><ul><li>You might want to cover your kaleidoscope's exterior to make it look nice. Try wallpaper, fabric, thin cork tile, paint, wood veneer, ribbon, yarn, heavy string, fold-dyed paper, tie-dyed cloth-whatever looks nice to you. </li></ul>
<ul><li>As you do step 3, tinker with the mirror angles. An equilateral arrangement will give you one set of images, a long isosceles triangle will give you another. Try using 2 mirrors and a piece of black cardboard. This gives you a startlingly different set of images. Or use 4 mirrors for more radically different images. If you omit the object case, you get a crude "teleidoscope"---a viewing instrument with no moving parts. Whatever you point it at will be reflected and multiplied. To do this well, you'll need to add some kind of magnifying lens. </li></ul>
