Elenco Snap Circuits Motion - Manual (Page 44)

Project 67 Not Too Much at Once
Use the preceding circuit, but remove the air fountain
(AF) and reinstall it with the switcher (S6) and a 2-snap
wire, as shown in the upper-right of the drawing. Note
that S6 and the 2-snap overhang without support, but
they should still be stable.
Turn on the slide switch (S1) to turn on the main circuit,
and set the switcher to the top position to turn on the
air fountain. The ball will wiggle and dance around on
top of the spout, but will not rise into the air. The rest of
the circuit works the same as in the preceding project.
!
WARNING: Moving parts. Do not
touch the fan during operation.
This circuit runs the air fountain (AF) at 3V
instead of 6V. Now the air fountain doesn’t
operate at full power, but it uses less
current from the batteries. The lower
current here will rarely (or never) activate
the fuse like it could in the preceding
project, and if the fuse does activate it
would only be after a much longer
operating time.

Mount the medium-small green gear on the geared motor, the
medium-large gear and the on the “+” shaped bar, place the bar in
the pivot stand and align the gears, place a colored disc or figures
on the merry-go-round base and mount it on the “+” bar. If gear slides
down shaft during use then add a rubber ring to keep it in place.
Place the spout
on top of the air
fountain and the
ball in the air flow.
