You will need: Disc (die-cut cardboard), short string
Here’s how: Separate the disc from the cardboard
and find the shorter string in the box. Guide its ends
through the small holes in the disc and carefully knot
them. Slide the disc to the middle of the length of cord
and slide the cord into the slit so the disc stays straight.
Holding the string tight with your
fingers, rotate the disc again and
again, like a jump rope, until the
string is really wound up. About
30 to 40 times should do it.
Now, pull the ends of the string apart with a lot of force and then immediately relax the tension
again! Be sure that the disc stays straight. Don’t give up right away — you’ll soon get the hang
of it. The disc will go faster and faster,
and you will hear a whizzing sound.
What’s happening? Why does the
disc make a noise when it spins fast? The spinning disc works by the same principle
as a top, except it is suspended from a string and gets its rotational momentum
from the turning of the string. The turbulence of the disc makes the air
around it vibrate. Depending on its rotational speed, you will hear
a whizzing or a sort of howling sound with a higher
or deeper pitch.

4. Spin, prey top!
You will need: Top disc (die-cut cardboard), top
Here’s how: Separate the colorful disc from the die-
cut cardboard and place it on the upper surface of
the top. Clear everything out of the box, which will
serve as your spinning surface. Now try to get the
top spinning!
What’s happening? Why does the top spin? Think about what hap-
pens when a train or car goes into a curve. There’s a force that
pushes your body outward. This force is called “centrifugal force.”
Any moving body persists in its direction of motion. This goes
for a car, too — and if it goes too fast, it can even fly out of the
curve and lose control.
But what does all that have to do with your top? When it
spins, the centrifugal force is greater than the force of grav-
ity pulling it downward. As it spins more slowly, the force
of gravity starts to take over, until it eventually topples.
You will need: Binoculars
Here’s how: Take the folding binoculars
out of the box and take a look at the
landscape…
What’s happening? The forward lens collects the incoming light, focuses it, and uses it to produce an
enlarged image of objects farther away. This lens is also called the “objective” lens. The other lens is
smaller, and enlarges the image a second time close to the eye. Unlike with a telescope, a pair of binoculars
lets you see the object in three dimensions, and with the proper width-to-height ratio.
3. Measuring weights with the scale
You will need: Scale (die-cut cardboard), a packet clip,
5 paper clips, 1 suction cup, a quarter and a dime
Here’s how: Assemble the scale as shown in the illustra-
tion. For the scale to read the correct weight, you need
to use one quarter and one dime as counterweights.
Carefully clip them to the scale as shown with two
paperclips.
Aach each of your
test objects in turn
to the paper clips and
read their weights on
the scale. Be sure that
the scale is set to “0”
before each weighing.
What’s happening?
All objects are pulled to the
center of Earth by gravity. The
greater the mass of an object, the
greater its weight and the more
strongly it’s pulled down.
You will need: Top, map sheet
Here’s how: In this game, try to get your top to
travel from one state to another on your map.
Clear everything out of the kit box so you can
have just the map lying inside it. Spin the top on
the map. By tilting the box, can you get the top to
travel along the roads and get it to stay in a specific
state?
2. Whoosh! The whizzing
sound of the spinning disc
Dear Parents,
This experiment kit will make long drives pass in
the blink of an eye. And at the same time, your
kids will learn playfully simple concepts from
the world of science. They will be able to study
the landscape with the binoculars, or try fun
games with the top and the spinning disc. They
can construct a miniature cable car or a simple
scale. And we haven’t forgotten about the fun
when you get where you’re going: In the box,
they will find a “multifaceted” postcard that they
can assemble themselves and a boomerang for
flight experiments. So here’s wishing you a safe
trip, and lots of fun with these experiments!
CAUTION!
Not suitable for children under 3 years of age.
There is a risk of suffocation due to small parts
that can be swallowed or inhaled. There is a risk
of strangulation if strings or cords are wrapped
around the neck. Save the packaging and instruc-
tions, as they contain important information.

binoculars work?
5. Tricky top game
Warning note: Caution! Never look
directly into the sun, either through
the binoculars or with your naked
eye. You could seriously damage
your eyes. Never leave the binocu-
lars lying in the sun – fire risk!

Tip
Insert a suction cup through the
hole in this instruction sheet and
stick it to the window. That way,
you will have the instructions
right in front of you while you
perform the experiments.
