Push the press switch (S2) to hear the
horn (W1).
Project 6
Horn
Project 7
Lamp
Use the circuit from project 7, but look at the lamp
(L4) through the prismatic film. Prismatic film is the
approximately 1.5” x 1” plastic sheet that is included
in this kit. Next, view different light sources in and
around your home through the prismatic film.
This circuit is the one shown on the box cover, use
that as a guide in building it. Push the press switch
(S2) to light the lamp (L4), sound the horn (W1), and
spin the motor (M1). When you release the switch, the
glow fan may rise into the air if it is spinning fast
enough. If the fan does not fly when released at full
speed then replace your batteries. If you do not want
the fan to fly off then reverse the position of the motor.
Project 9
Light, Sound, & Motion
Push the press switch (S2) to light
the lamp (L4), sound the horn
(W1), and spin the motor (M1).
The fan probably will not rise into
the air as it did in project 9,
because the motor isn’t spinning it
as fast now.
Now swap the locations of the motor
(M1) and lamp (L4); the motor can
be oriented in either direction.
Compare the performance.
Project 5
Strobe the House Lights
You need an old fluorescent light for this project. Use the circuit from
project #4. Using a blank cutout, draw several straight lines from the
edges through the center, evenly spaced like spokes on a bicycle wheel.
Place the cutout on the fan and place atop the motor.
Place the circuit under a fluorescent light in your home and spin the disc
slowly. As the speed changes, you may notice the lines first seem to move
in one direction, then they start moving in another direction. This effect is
because the lights are blinking 120 times a second and the changing
speed of the motor is acting like a strobe light to catch the motion at
certain speeds. This project won’t work with most new fluorescent lights,
because they use an electronic ballast that produces a constant light.
Project 8
Spectrum of Light
Project 10
Combination
Prismatic film
Push the switch (S2) to light the lamp (L4).
Prismatic
film
separates light into
different colors,
and can make
interesting light
effects. White light
is a combination of
all colors.
Here the motor, horn, and lamp
are connected in parallel; if one or
two of them burn out, the other(s)
will still work. The switch is
connected in series with all of
them; if it breaks, nothing will
work. Electricity flows out of the
batteries, through either the
motor, horn, or lamp, then back to
the batteries through the switch.
WARNING:
Moving parts.
Do not touch the motor or
fan during operation. Do not
lean over the motor. Fan may not
rise until switch is released. Do not
launch fan at people, animals, or
objects. Eye protection is
recommended.

This circuit is similar to project 9, except here all the electricity
from the batteries flows through the lamp, then the motor and
horn, then back to the batteries through the switch. The
battery voltage is split between the lamp, motor, and horn,
making the motor slower, the horn quieter, and the lamp
dimmer. The batteries will last longer now, because electricity
isn’t flowing out of them as fast as in project 9.
A light bulb, such as in this
lamp, contains a special
then high-resistance wire.
When a lot of electricity
flows through, this wire
gets gets so hot it glows
bright. Voltages above the
bulb’s rating can burn out
the wire.
The horn converts elec-
tricity into sound by
making mechanical vibra-
tions. These vibrations
create variations in air
pressure which travel
across the room. You
“hear” when your ears
feel these air pressure
variations.
