You now have 20 different fiber optics experiments to your credit. From this point, we move on
to projects in which you will create lasting fiber optics devices that you can use to impress your fellow
students, parents, grandparents and friends.

Penlight with batteries
Black rubber penlight boot
Multifiber light guide which you constructed in Experiment 17
Single-edge razor blade or sharp knife*
Alcohol lamp, Bunsen burner or propane torch*
* Not contained in this kit.

• With the rubber boot removed from the penlight, insert the multifiber light guide end closest to
the heat shrink through the hole on the rounded side of the boot until the fibers extend 2 cm
(3/4 inch) beyond the flat base of the boot.
• Turn on your heat source and carefully heat the fiber ends extending through the rubber boot
until they melt together just slightly. Turn off the heat source and let the fiber ends cool about 5
minutes.
• Pull the fiber ends back through the hole in the rubber boot until they extend only about 1 cm
(3/8 inch) into the boot.
• Fit the rubber boot over the penlight and turn the light on.
• Dim the room lights and close all window coverings. (You may also go outside if it's nighttime.)
Observe the light going through the fibers and exiting the fiber ends. Shake or move the penlight
about.
• To change the colors of light
coming from the fiber ends,
remove the rubber boot and
cut red, green, or blue plastic
filter material to fit inside the
rubber boot. To make a
multicolor wand, use several
colors and experiment with
different positions.
• After you have completed
Project #4, you can apply
some of the techniques that
you learned in Experiment
#7 to make your light wand
reflect your personal designs.
