How do you make a Kaleidoscope
“Kaleidoscope" is derived from Greek words meaning "an instrument with which we can see things of beautiful form." The kaleidoscope was rediscovered in 1817 by Sir David Brewster, who published a treatise on it two years later. These instructions are for its simplest form, which consists of three mirrors taped together to form a hollow triangle. Placing these mirrors inside a hollow tube and rotating lets you see changing patterns.
Step 1
Cut tubing to desired length and smooth any rough edges.
-
Step 2
Trim the mirrors so that their length is the same as that of the tubing and their width is less than its diameter. Make a cardboard model of the mirror before cutting the mirror itself to be sure your mirrors will fit in the tube.
-
Step 3
Arrange the mirrors, reflective sides in, to form an equilateral triangle and wrap duct tape around the outside to hold them together.
-
Step 4
Insert the mirrors into the tubing. Pack them in place with foam rubber or foam peanuts, if necessary.
-
Step 5
Make a cardboard disk the same diameter as the tubing and poke a hole in its center. Glue this to one end of the tubing.
-
Step 1
Cut two lenses of clear plastic the same diameter as the tubing.
-
Step 2
Make a one-inch wide strip of cardboard slightly longer than the circumference of the tubing. Glue the ends together.
-
Step 3
Glue the cardboard ring to one of the lenses.
-
Step 4
Place the objects to be viewed on the lens with the ring attached, enough to cover the bottom, but not enough to prevent them from tumbling around after the other lens is glued to the ring.
-
Step 5
Affix the other lens to the cardboard ring.
-
Step 1
Attach the object chamber to the open end of the tubing.
-
Step 2
Hold the assembled kaleidoscope to the light to view the patterns created by the mirrors.
-
Step 3
Rotate the kaleidoscope to see the patterns change.
