After you have conducted the experiments on
pages 5–11, you can try out these more challenging
setups. Use what you have learned from the previous
experiments to adjust the setups until they work
properly. Can you get a gumball to make it all the way
to the bottom, landing every stunt?
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 10), 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.

Rotate the model
180 degrees
so the knob is
facing forward
again. Attach the
centripetal force
funnel to peg
4
on the side of the
tower under the
knob, and peg
4
on the side to the
left of that, as
shown.
