Follow these steps to build the first configuration of
the gumball machine. Beforehand, assemble the tower
according to the steps on pages 2 and 3. Refer to the
descriptions of the tracks and stunts on pages 4–7 for
important background information.
HERE’S HOW
1
With the rubber bands wrapped around the
trampoline ring, and the trampoline attached to the
straight pivot post (as described on page 6), attach
the trampoline with the pivot post to the tower.
Attach it to the side of the tower under the dispenser
knob, on the second and third pegs from the top;
that is, pegs
2
and
3
.
2
Rotate the model 180 degrees so the knob is facing
backward. Attach the pendulum with the angled
pivot post to pegs
3
and
4
on the side of the tower
opposite the knob.
