Build the circuit. Place the merry-go-round
base on the geared motor (GM) shaft; if
desired, insert some of the cardboard
figures into the base or install one of the
colored discs into it. Turn on the slide
switch (S1).
The geared motor spins the merry-go-
round, the light motor (M7) spins and
lights, and the air fountain (AF) blows air.
Place the ball directly in the blowing air
above the air fountain. The blowing air
should balance the ball, so it floats in the
air and “dances”. Occasionally the ball
may become unstable and fall out; just
place it back into the air flow.
NOTE: this circuit may work for a while and
then suddenly shut down. If so, turn off the
slide switch, wait a little while, and then turn
it back on. Snappy explains why in project 66.

Triple Motion
!
WARNING:
Moving parts. Do not
touch the fan during operation.
Project 118
Slow Triple
Motion
Use the preceding circuit but
replace one of the battery
holders (B1) with a 3-snap
wire. Now the merry-go-round
(on the geared motor (GM))
spins slower, the light motor
barely spins & lights (it may
even need a push to get
started), and the air fountain
may not be able to get the ball
into the air. The difference in
performance will be greater if
your batteries are weak.
Build the circuit. If desired, place the merry-go-round base on the
geared motor (GM) shaft and insert some of the cardboard figures
into the base or install one of the colored discs into it. Turn on the
slide switch (S1).
The geared motor shaft may spin, the light motor (M7) may spin,
and the air fountain (AF) may blow air, but probably not all of them.
Project 119
Dominator
!
WARNING:
Moving parts. Do not
touch the fan during operation.

Place
the
spout on top
of the air
fountain and
the ball in the
air flow.
Spout
The geared motor, light motor, and air fountain all
contain motors, used in different ways. Here they are
connected in series, so the one that most resists the
flow of electricity (needing the least electric current
to operate) will dominate the circuit, restricting the
electricity to the others. Often the geared motor will
dominate, with the light motor and air fountain having
electricity flowing through them but not enough to
function properly, but your results may vary.
