Tess and RobyThe two friends share a spooky camping adventure.

Around the world, people play nearly 500 different types of sport. But one of them is a huge favorite: soccer. Our ancestors in China were kicking balls around as early as 4,000 years ago. Those ones were made from sewn-up bits of leather and filled with animal hairs and feathers.

However, England was the origin of the soccer match as we know it today. There, the first rules were established about 150 years ago.

In TÜVtel, you‘ll discover how soccer was transformed from a massive brawl over a ball made from fabric pieces into an orderly match, as well as plenty of other special facts about the popular ball game.

Hey, TÜV kids!

Ticks are little vampires. With their spine-like mouth parts, they prick the skin to suck out blood. They like biting legs best. While it doesn't hurt, you can get sick from a tick bite.

The tiny creatures usually sit on blades of grass or among the leaves and wait for their next victim. Are you often in the garden, in parks, in meadows or near the forest in the summer? TÜV Rheinland

has some tips on how you can protect yourself from tick bites: • Wear light-colored clothing: It helps you to

spot ticks straight away. • Cover up: Protect your arms and legs with long-sleeved shirts and long pants.

• Keep your feet safe: Wear socks and closed shoes.

• Look closely: Get your parents to check you all over after outdoor adventures.If a tick does get hold of you, it should

carefully be removed immediately with a pair of tick tweezers or a tick card.

"I am in high demand. People run after me wherever I roll or fly. Everything on the field

revolves around me. I am the round thing that has to go into the rectangular hole. I am a soccer ball. I bet you are thinking: "Ha ha, he is so full of hot air!" But honestly, would you want to play with me if I was all floppy? Probably not. And I want to play! I want to be passed, dribbled and slammed into the nearest goal with plenty of oomph - at least as well as my famous relative Brazuca, the 2014 World Cup ball from Brazil. He is a real star right now and he looks great with his unmistakable colored loops. But when it comes to being kicked into the opponent's goal, we are all just the same.

Soccer is the most popular sport on our planet.

Stadium Seats Under Scrutiny Stadium seats have a lot to cope with:

Elated fans leap up cheering and then

plonk themselves back down again.

They slide nervously back and forth and

shake the backrests wildly. Despite that,

of course all spectators still want to

sit safely and comfortably. That is why

at the furniture testing institute, TÜV

Rheinland examines whether stadium

seats can withstand the heavy strain.

A Quick WaveA Mexican wave speeds through the stadium at a rate of about 12 meters a second. That makes 20 seats per second, a fact that was established by physicists from the TU Dresden university using video footage.

In comparison, the world's fastest runner, Usain Bolt, covers

100 meters in 9.58 seconds. At that pace, he would not stand a chance of

catching up with the speedy wave.

In the hot seat: These chairs are being rocked,

pushed, pulled and shaken for all they're

worth.

An unexplained phenomenon: Mexican waves almost always move in a clockwise direction.

Tsu Chu came firstThe Chinese already played a game similar to soccer more than 4,000 years ago. It was called Tsu Chu and the aim was to get a leather ball into a narrow net that was attached to two bamboo poles. The players could only touch my feather and hair-filled ancestors with their feet, chests, backs and shoulders. To be a great Tsu Chu player, you needed a whole lot of practice and agility, as well as very good body control.

Brawling for the Ball It was a completely different story in medieval England. Brute force was what counted there. I would not have liked to have been in use back then. The balls were made of scraps of cloth that were held together by a net and they were as big as medicine balls. They were not very attractive, I tell you, especially not after they had been trampled on for several hours by countless feet. At the time, it was not just two teams of 11 players competing against each other for 90 minutes, but two entire villages playing for several hours. The town gates were the soccer goals and everyone could join in. There were hardly any rules. People would push, kick and hit each other. They could do anything they liked to get the ball.

What many people dream of: kicking like a pro from the German national team.

Miracle CleatsFor a long time, soccer players slid uncontrollably

over the ground in rough shoes that had leather

cleats nailed to the soles. They missed many

scoring opportunities in the process. Just in time

for the 1954 World Cup in Switzerland, Adi Dassler,

the founder of the company Adidas, equipped

the German team with soccer shoes that had

replaceable screw-on cleats. With those on

their feet, the German team defeated the

very strong Hungarian team 3:2 and took

home the World Cup title. The legendary

match took place in the Swiss capital of

Bern, so many people refer to it as the

"miracle of Bern".

Ende

Rules upon rulesBecause soccer mostly ended up causing a major brawl, the authorities tried to ban it time and time again. They were not successful, which is lucky for me because otherwise I would be totally useless! However, they did gradually introduce more rules to reduce the number of injuries. While things are not quite as rough these days, soccer players still jostle, jump on and push each other, so now there is a referee to keep everything under control. For 124 years, the referee has been the only person in charge, constantly reminding players that along with a flawless technique, a good game also requires fairness, team spirit and self control.

Not only the players had to follow new rules. Nothing was left to chance on the field either - at least not in today's professional soccer. For example, the playing field for the World Cup has to be exactly 105 meters long and 68 meters wide. The distance between the goal posts is 7.32 meters. Each link in the goal netting has a diameter of 12 centimeters. And so on and so forth. Of course, you don't have to worry about all of that if you are just going out for a kick. All you need is some space, two goals, a few friends and one of my colleagues. And a lot more team spirit than people had in the Middle Ages!" ;-)

TÜVtel shows you how the lion knight's Empire

castle was made.

On the PC: First, the plans

are drawn up and models are

built out of cardboard and

foam. The best model is then

reconstructed on

the computer.

Brainwork: Head of Development Bernhard Hane and his employees look at books, exhibitions and films about knights' castles. They also read letters from children about how they think castles should look and what they wish for.

Fits the mold: Using the computer data, an injection mold is created for each part. The Lion Knight's Empire Castle has 290 individual pieces!

The main ingredient: PLAYMOBILis made out of synthetic granules. The beads are melted and poured into the injection molds.

From beads to Castles

11TÜVtel

Piece by piece: At the factory in the Bavarian town of Dietenhofen, there are more than 420 injection molding machines. Each part of the castle is produced by a different one of them.

A quick makeover: Some pieces, like the castle gates, go to the printer for a more detailed design.

Making mini people: All

figures are made at a factory

in Malta, including the castle

inhabitants.

All packed: On the assembly

line, all the castle pieces and

figures go into a box together.

They are weighed to check

that nothing is missing.

Bye bye: The finished castles are delivered to the toy stores.

Luckily for Tess, Roby remembered to pack the fan.

Many people cool their homes with air conditioners. The

appliances have the task of transporting heat from one place

to another and then releasing it there.

Split air conditioning systems are very popular. "They consist

of two parts. The evaporator is located inside the house and

the condenser is outside," explains Stephan Scheuer. The

expert on electrical appliances from TÜV Rheinland describes

how a split air conditioner works.

It goes like this: A refrigerant evaporates inside the indoor

unit, turns into a gas and takes up the heat in the room.

It is transferred to the outdoor unit via a pipe and is then

released into the air as heat. The refrigerant liquefies again

and flows back into the indoor unit through a second pipe.

The cycle continues until the desired room temperature has

been reached.

In ancient Egypt, the rulers made their servants fan them with giant fronds. That must have been exhausting - at least for the servants. An appliance that cooled the air automatically would have been much more practical.

Such a device was invented many thousands of years later by the engineer Willis Haviland Carrier. He spent a long time tinkering away at a machine that could cool down warm air, clean it with filters and then moisten it. It was finally ready for use in 1902, but sadly nobody wanted to buy one. It wasn't until 12 years later that he managed to convinced a cinema owner in New York to install one of his cooling units. The moviegoers loved it. That was the breakthrough for the air conditioner.

Today, air conditioners are in great demand. They cool down huge buildings like airports, production plants and supermarkets, as well as houses and cars.

14TÜVtel

For a picture to be transmitted to a television screen, it has to be broken down into lots of individual dots. These are called pixels. The pixels for each image are transferred electronically and then put themselves back together bit by bit on the screen. This happens extremely fast. The more pixels a television picture has, the sharper the image will appear. At least that is the case for high-quality televisions. TÜV Rheinland checks whether their resolution is good. At the laboratory, it also tests their reception, as well as the colors and contrasts they display.

The Spirit of the Forest

Tess and Roby

A cloud passes in front of the moon and the sky above the forest campsite darkens. Tess yawns. A few bats flutter around the tent looking for tasty insects. Then everything is still. Tess and Roby decide to go back to their tent and cuddle up in their sleeping bags. Suddenly, a loud screech pierces the night. Roby gives a start. “It‘s only an owl,” says Tess reassuringly. But then there is something else. A gentle rustling. “Do you have an explanation for that, too?” whispers Roby.

“And suddenly there was a terrible creaking. The bark sprang off the trunk of the old oak tree and a hideous, scowling face appeared. It was the spirit of the forest. With its flashing yellow eyes, it stared furiously at the children. The oak's branches whipped wildly through the air while the roots shot up out of the ground and tried to grab hold of the children. Nobody knows if they escaped because they were never seen again.” Tess paused dramatically.

“And, are you scared now?” she asks her friend Roby, giggling. No of course Roby isn't scared. After all, there is no such thing as a spirit, let alone a monster tree. But then a good horror story is part of the deal when you go camping.

Bread on a Stick

For this tasty campfire treat, you need 500 grams of flour, 1 sachet of dry yeast, 2 tablespoons of salt, 2 tablespoons of oil, 250 milliliters of warm water and some sticks that are as thick as your finger.

This is how it goes: Knead the ingredients into a dough and let it stand for one hour (preferably in a warm place). Roll the dough into sausages two centimeters thick and wrap each one around a stick. Hold them over the embers and turn them slowly until the bread is golden brown.

Tess and Roby are looking forward to camping out in the tent. Then the witching hour strikes.

Tess listens. Something makes an ominous cracking sound in the bushes. A rabbit, perhaps? The friends peer apprehensively into the darkness. Tess shines her torch around. And then something unbelievable happens: Someone is staring right back at them! Two enormous yellow eyes are glaring at them. Frozen with fear, they hold their breath as the eyes come closer. And closer. Then Roby can't stand it any longer. He cries out “Aaaaaaaah, the spirit of the forest! It's coming to get us!”

The TÜV Rheinland fire safety experts have some

tips for you:

• Always only build a campfire in a permitted area

• Light it together with an adult • Make sure it is a safe distance from things that can

burn, like tents, bushes or trees • Pay attention to the wind. It can create dangerous

flying sparks• Keep a bucket of water nearby for emergencies

• After you have extinguished the flames, scatter sand

Tess and Roby

Tess tries to jump up but Roby is clinging desperately to her leg. They tumble over each other. Startled by the commotion, the owl screeches loudly from its tree. Tess crawls frantically into the shelter of the tent. Roby stumbles in behind her. “Shut the tent! Quick!” cries Tess. Roby tugs wildly at the zipper. Zzzzipp! Made it! Inside, they cower in their sleeping bags in complete silence. Tess can feel her heart racing. Roby the little robot is trembling so badly that his steel joints are rattling.

“Go away, go away, go away,” he whispers, screwing up his eyes. Then he tugs his sleeping bag over his head with a jerk. His plan is to see nothing, hear nothing and simply wait until the spirit disappears. Tess notices a shadow creeping along the tent canvas. She watches as it stops, pauses for a moment and then grows further away again. Her heartbeat calms down. Tess takes a deep breath. “I think it is gone. Should we go home and sleep there instead?” she murmers in Roby's direction. The robot pops out from inside his sleeping bag. “I'm not moving a single centimeter from this tent until morning,” he says, burrowing back into his sleeping bag.

While Tess is still desperately trying to work out what just happened, she is overcome with tiredness and falls into a restless sleep. “Meow.” Tess opens her eyes. Phew, luckily the spooky feeling has gone. She still feels exhausted though. “Meow, meow.” The sun shines on the tent, bathing the interior in a soft golden light. “Meeooooowww.” What on earth is that? Tess creeps out of her sleeping bag, opens the tent and peers out cautiously. A little cat is sitting there, watching her with big eyes. Tess pauses. Those eyes, hmmm, somehow they seem familiar to her. Suddenly she realizes.

night Vision

Some animals can see very well in the dark, including owls, deer, foxes and cats. They have particularly large pupils that can detect even the tiniest spark of light. It lands on the retina, where there are many cells that respond to light and dark impulses. These cells are called rods. We humans also have rod cells in our eyes but we have far fewer of them. That is why we can‘t see at all well at night. But then we don‘t need to. After all, we are asleep.

Behind the Scenes

20TÜVtel

What are you

Testing there?

Water slides!

?

Hans Küpper Tests water slides for TÜV Rheinland and also likes sliding himself.

Inspectors in Flip-Flops

Hans Küpper is on an important mission. Today he wants to find out whether the water slide at the Aquapark in Majorca is in good shape. He doesn't have any tools with him. Instead, he has brought one of his colleagues. After all, two pairs of expert eyes see more than one.

First, the inspectors look at the construction. The base and attachments have to be stable and must not have any rusty areas. That happens fast at indoor swimming pools because the air contains high levels of moisture and chlorine that damage the steel.

Next, they check the surface of the slide, paying particular attention to the areas where the individual sections are joined together. If they are not connected properly, they have to be sealed with silicon. Otherwise people will get bruises when they slide.

The water on the slide is drawn up from the swimming pool and the suction mechanisms have to be inspected as well. If they suck too hard, a swimmer could be pulled into them. That has already caused serious accidents in the past.

Finally, Hans Küpper also slides down himself. That way, he can test the speed and get a better idea of the danger spots. His verdict today: Everything is in top condition.

SpeedY SlidingChampion sliders swear by the three point technique.

That involves lying on your back, folding your arms in

front of your chest, crossing your outstretched legs and

lifting up your bottom. Only your shoulder blades and one

heel should be touching the slide. That way, you displace

less water. Because the resistance is lower, your speed

increases.

The more of your body is touching the water slide,

the slower the ride becomes.

laboratory tests how much a

water toy can withstand.

Rubber rubbish?

nO way!

You can also speed down water slides on inflatable

aquatic toys. However, many of them are cheap junk that

you can even injure yourself on. TÜV Rheinland tests lilos,

swimming rings and rubber toys, so it knows how you

can identify poor quality products:

Nose: If the toys stink, it can be a sign that the rubber

contains harmful solvents. Junk!

Hands: Run your finger carefully over the seams. If

the edges are sharp, you might scratch yourself while

you are playing with the toy. Junk!

Eyes: Check whether it has a GS mark. That

stands for tested safety and it means that the

toy has been carefully examined by professional

inspectors, for example from TÜV Rheinland. It is

safe!

What you expect: You would assume that the air from the inflated balloon would flow into the empty one until they were both equally full. That is the law of pressure equalization. But nothing happens! Why? The tension in the rubber is to blame. The air is not strong enough to spread into the floppy balloon by itself. A law of nature has quite simply been outsmarted.

Q&AYou ask, we answer.

What Linus wants to know: Why does

the sunflower turn its face towards

the sun?

Dear Linus! While a sunflower is growing, it

stretches its head towards the sun so that

it can catch more light. As the sun moves

across the sky, the flower follows. Day in, day

out, it turns from east to west and then back

again at night-time. This happens thanks to a

special material that makes the plant grow faster

on its shaded side. The uneven growth causes the

flower to turn its head. Once the plant is fully grown,

it only points towards the east.

Big Ears

Chill Out, Big Ears!

The fennec lives in hot steppe regions and deserts. To stop itself from overheating, the little fox uses its huge ears as heat exchangers. If it gets too warm, the blood vessels in its ears dilate and release the extra body heat into the air. Its relative, the arctic fox, has extremely small ears. That is often the case in animals that live in icy cold regions. That way, they hardly lose any heat from that part of their body. The same phenomenon can be observed in brown bears and polar bears.

Like the fennec, the African elephant also pumps warm blood into its mighty ears. It flaps them to cool down the blood, which then flows back into the body to refresh the thick-skinned animal from the inside. Asian elephants have much smaller ears. That is because they mainly live in colder forest areas and don‘t need the huge cooling systems of their African counterparts.

Iguaçu Falls

A Gigantic Spectacle

Brazil not only hosted the 2014 World Cup: It also has many natural wonders to offer. Thundering masses of water, fine mists and dazzling rainbows: Together, the 20 large and 255 small waterfalls in Iguaçu form the biggest waterfall in the world. It is located on the border between Brazil and Argentina. There, the water plummets up to 80 meters into the depths. The rainforest surrounds it, offering shelter to countless animals. Everywhere there is buzzing, croaking and chirping. Luminous butterflies float through the air and tiny hummingbirds sip sweet nectar from colorful flowers. A jaguar slinks silently through the undergrowth. Excited monkeys can be heard screaming in the distance, interspersed with the screeches of a hyacinth macaw. Once you‘ve been to the Iguaçu Falls, you never forget the gigantic spectacle of nature.
