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
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.
Whats 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.
Contents
1 pair of binoculars 3 suction cups
5 paper clips 1 packet clip
2 lengths of string 1 top
1 die-cut cardboard 1 map
4. Spin, prey 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 theobjective” 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
Heres 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.
Aach 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!

At your vacation destination:
A boomerang for
cool flight tests
You will need: Boomerang (die-cut cardboard)
Here’s How: The boomerang can function as
both hunting weapon and sporting equipment.
The Australian Aborigines are expert boomerang
makers and throwers. They know how to design
this flying instrument so it always comes back to
the person who throws it. The boomerang in the
die-cut cardboard is admiedly not perfect, but
with a lile bit of skill and patience you can try
different throwing angles to see which one works
best to make it come back to you.
Tip: When you
throw it, a quick
flick of the wrist will
help your boomerang
get off to a great start.
A lile practice makes
perfect…
If it doesn’t work, trying
throwing the boomerang
like a Frisbee.
What’s happening? How does a boomerang fly
and why does it return to its thrower? As a boo-
merang spins through the air, it rotates around
an axis passing vertically through its center. As it
does this, it follows a parabolic path that ideally
leads back to the starting point.
The “multifaceted”
postcard
You will need: Postcard (die-cut cardboard)
Heres how: Fold the strips with the orange-
colored picture of the pyramids facing up, as
shown in the drawing. You will see a different
picture depending on which side you look at the
postcard from.
7. Fun travel route calculations
You will need: String, experiment ruler (die-cut
cardboard), large driving map or driving atlas
How far is my travel route (in miles)?
Here’s how: Use your experiment ruler and string to
measure the approximate length of the travel route on
the driving map (or driving atlas). Take a look at the
scale used for the map and then convert your travel
distance from inches into miles. Map scales are usually
represented as ratios, such as 1 inch to 63,360 inches,
which can be wrien as 1:63,360, or one inch to one mile.
How fast am I traveling?
Here’s how: Would you like to calculate your average driving speed (v, for velocity)? If so, you will need:
d = Distance: The length of the driving route in miles. For this, you can ask your parents, the train
conductor, or the flight aendant. Or measure it on your map or in your atlas.
t = Time: The travel time in hours, not including stops or breaks.
Now, if you use the formula you will get the answer.v = d ÷ t
Example:
6. The “window-suction cup cable car”
You will need: Gondola (die-cut cardboard), long string, 2 suction cups
Here’s how: First, separate the gondola piece from the die-cut cardboard and carefully fold
it together. Take the longer string, thread its ends through the gondola eyelets, and knot it
in place there. Now hang the string over the two suction cups. You will be able to move the
cable car from left to right by pulling the string. What sorts of things can you transport in it?

Fun Questions
1. How far do animals travel?
A lot of animals move between summer and winter homes every
year. Arctic Terns migrate from the Arctic to Antarctica and back
again each year, about 12,000 miles each way. They live up to 25
years and cover as much as 1.5 million miles in a lifetime! Take a
look in your world atlas to see how great the distance is between
the Arctic and Antarctica.
European storks cover up to 250 miles a day as they travel back
to South Africa. They take advantage of updrafts and soar like
gliders in order to save energy.
Ask your travel companions to think of other animals
that take long trips — in the ocean, in the air, or on
land. The winner is whoever can name the most
animals in 10 minutes.
2. How fast does Earth travel in its orbit?
Our planet circles around the sun. Take turns guessing
how fast Earth might be moving as it does this. Who
can get the closest to the right answer?
As our Earth follows its orbit around the sun, it
reaches an average speed of 29,800 meters per second
– or 66,660 miles per hour!
Common map scales What it means in reality
1 : 24,000 1 inch on the map corresponds to 24,000 inches, or 2,000 feet, in reality
1 : 63,360 1 inch on the map corresponds to 63,360 inches, or 1 mile, in reality
1 : 500,000
1 inch on the map corresponds to 500,000 inches, or about 8 miles, in reality
Driving route from New York, NY to Los Angeles, CA
d about 2,450 miles
t about 44 hours
v 2,450 miles ÷ 44 hours = 56 miles per hour (mi/h)
