WARNING: SHOCK HAZARD
-
Never connect Snap Circuits
®
to the electrical outlets in your
home in any way!
WARNING:
Always check your wiring before
turning on a circuit. Never leave a circuit
unattended while the batteries are installed.
Never connect additional batteries or any other
power sources to your circuits.

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.
Snap Circuits
®
uses electronic blocks that snap onto a base grid to build different circuits. These blocks
have different colors and numbers on them so that you can easily identify them. Build the circuit shown
by placing all the parts with a black
1
next to them on the clear base grid first. Then, assemble parts
marked with a
2
. Install three (3) “AA” batteries (not included) into the battery holder (B3). Place the
glow fan on the motor (M1).
When you press the press switch (S2), the motor will slowly increase in speed. When the motor has
reached maximum rotation, release the press switch. The fan should rise and float through the air like
a flying saucer. Be careful not to look directly down on the fan while it is spinning.
The glow fan will glow in the dark. It will glow best after absorbing sunlight for a while. The glow fan is
made of plastic, so be careful not to let it get hot enough to melt. The glow looks best in a dimly lit room.
Rebuild the circuit from project #1, but reverse the polarity on the motor so
the positive (+) on the motor goes to the positive (+) on the battery holder
(B3). Place the fan on the motor and press the press switch (S2). Current
flows from the batteries through the motor (M1), making it spin the fan. The
fan blows air up and away from the motor, just like an electric fan in your
home. The fan will not fly off.
Use the circuit from project #3. Using the fan as a guide, draw a circle on a
piece of cardboard or paper. Cut the circle out with scissors and tape it to
the fan blade so it can be easily removed later (you may remove the red
spiral pattern first). Obtain some thin and thick marking pens to use as
drawing tools.
Spin the paper by pressing and holding the press switch (S2) down. Gently
press the marker on the paper to form rings. To make spiral drawings,
release the press switch and as the motor approaches a slow speed, move
the marker from the inside outward quickly.
Change the colors often and avoid using too much black to get hypnotic
effects. Another method is to make colorful shapes on the disc then spin the
disc and watch them blend into each other.
Rebuild the circuit from project #1, but reverse the polarity on the motor (M1)
so the positive (+) on the motor goes to the positive (+) on the battery holder
(B3).
Cut out the printed pattern from the cardboard along the dotted line with
scissors and tape it to the fan blade. Spin the pattern by briefly pressing the
press switch (S2). You will see the most interesting effects when the pattern
is spinning slowly.
Project 1
Flying Saucer
Placement
Level Numbers
In this project, the air is being blown down through the blade and the motor rotation
locks the fan on the shaft. When the motor is turned off, the blade unlocks from the
shaft and is free to act as a propeller and fly through the air. If the speed of rotation
is too slow, the fan will remain on the motor shaft because it does not have enough
lift to propel it. The motor will spin faster when the batteries are new.
The motor converts elecricity into mechanical motion. Electricity is closely related to
magnetism, and an electric current flowing in a wire has a magnetic field similar to
that of a very, very tiny magnet. Inside the motor is are three coils of wire with many
loops. If a large electric current flows through the loops, the magnetic effects become
concentrated enough to move the coils. The motor has a magnet inside so, as the
electricity moves the coils to align them with the permanent magnet, the shaft spins.
The battery voltage is like electrical pressure, pushing electricity through the circuit.
