Handleiding

Rotate the model 90 degrees. Attach the

pendulum with the angled pivot post to pegs

and

as shown.

Rotate the model 180 degrees. Attach the

centripetal force funnel to pegs

and

Hang the collection cup on the edge of the

base, under the centripetal force funnel.

Adjust all the tracks and stunts so that, in

your best estimation, a gumball will travel

all the way from the dispenser down to

the collection cup. Place a gumball in the

momentum trap. It is optional to start with

a gumball or two in the tip-over tube. The

assembly is finished!

Now it’s time to test the setup!

Follow steps 8 through 11 on page 14 like

you did for the first setup. You will need to

adjust the angle of the variable-slope track

to get the gumballs to roll out of it.

After a run, return the gumball to the globe

each time by taking the collection cup and

dumping it into the globe funnel.

WHAT’S HAPPENING

In a perfect run, the machine works like this: The

tracks and stunts function similar to how they

did in the previous setups. The new elements in

this setup are the friction track and the

pendulum. The friction track slows the gumball

down. You might notice the gumball makes

more sound when it goes down the friction

track. The pendulum swings over and drops a

gumball into the centripetal force funnel. As in

the previous setup, the tip-over tube might need

a little nudge to tip over. On its lowest setting,

the gumballs don’t roll out of the variable-

slope track after being dumped there from the

tip-over tube. Try increasing the slope of the

track and observing what happens.

Design your own!

Now that you know how all the

parts of the gumball machine system work, you can

design, build, and test your own configurations.

As a challenge, can you make a gumball machine in

which the gumballs make it to the bottom every single

time they are dispensed?

Done!
