Project 67 Prismatic Film Project 68
Look at the
Lights
View different light sources in and around
your home through the prismatic film.
This is the same circuit as project 1, but you will view it
differently. Turn on the switch (S1), and view the LED
through the prismatic film (the clear slide). Prismatic film
makes interesting light effects.
Replace the color LED (D8) with the white LED (D6)
and red LED (D1); view them through the prismatic film.
Project 70
Color Fiber Light
Prismatic film separates light
into different colors. White
light is a combination of all
colors.
Use the project 67 circuit, but view
the color LED through various semi-
transparent liquids, glassware, and
plastics. Juices, jello, and cloudy
glass or plastic work well.
Replace the color LED with the
white LED (D6). The white LED is
brighter, but does not change color.
Semi-transparent materials
scatter the light without
completely blocking it, so a
wide area of the liquid or
material is lit up by the light.
This happens in the egg and
tower LED attachments.
Use the circuit from project 67, but place the clear cable
holder on the color LED (D8), then place the fiber optic
cable into the holder as far as it will go. Turn on the
switch, then take the circuit into a dimly lit room and see
the light coming out the open end of the cable. The light
travels through the cable even as you bend it around.
