Sometimes, common items have intriguing properties
.................................................................................................................................
In this project you will use a simple round plastic ball which can act like a lens. This effect can be
used with an image conduit to produce a fiber optic product that will magnify images.

3 mm diameter × 2.5 cm (1/8 × 1 inch) image conduit (glass-like rod)
12 mm(1/2 inch) diameter clear plastic ball
Hot glue gun and glue (or clear silicone)*
Isopropyl alcohol*
Cotton swabs*
* Not contained in this kit.

• If using a hot glue gun, turn it on now. Clean one end of the image conduit with a cotton swab
and alcohol.
• Place a small ball of hot
glue (or clear silicone )
on the cleaned end of the
conduit. Quickly place
the plastic ball onto the
glue and glass rod so it
looks as shown here. Set
the ball/conduit aside for
the adhesive to cool (or
wait several hours for
silicone to harden).
• Once the adhesive has
hardened, place the flat
end of the image conduit
over the printed text on
this page. Move the end
of the guide over the
surface of the page while
observing the image
which appears through
the glass ball. How is the
image different than the
one you saw in Experiment 13, using the image guide without the ball attached?
• If you have a very clear marble, you may also be able to use it as a lens. Remove the ball and
adhesive and repeat the steps above, using the marble. (Hot glue and silicone are not
permanent.)
R R R R EEEE SSSS UU U U LLLL TTTT SSSS ::::
When the ball is on the viewing end (top) of the image
conduit, the image will appear larger than when using only the
image conduit itself.

The glass ball in this experiment acts as a lens. Attached to the image conduit, it acted as an
enlarging lens. This effect is illustrated in the figure to the right.
