For the water gun:

WARNING!

Dear Researchers, Please read the instructions carefully. This will allow you to avoid possible dangers!

Correct handling of the components and models → So you enjoy using your experimental kit, you should include Note: Even if some components are small, they can be very important for building various models. Therefore, pay close attention to the parts that are not needed by the model and put them in a sealable bag. → In the process of operating the model, water will splash out. Therefore, when experimenting, you can choose to be in a humid place (such as in the bathroom). After the experi-

Ti p 3

ment, please wipe the model and keep it dry.

Of course, you can also experiment happily outdoors.

Playing in the Water → If you want to try the models on a outdoor territorial waters, please note two things: Don't play alone in the water. If there is a situation, for example, in case you accidentally fall into the water, someone can immediately notice. Therefore, it is critical to ask an adult to accompany you. Second, you should tie the boat with a cord or string. Even if they go far away, they will not be lost.

You need the PEG REMOVER to remove the previous model.

It has TWO DIFFERENT SIDES for different functions.

— WATER POWER MINI 2.0 — IMPORTANT INFORMATION

Dear Parents and Adults, Children want to explore, understand, and create new things.

They want to try things and do it by themselves. They want to gain knowledge!

They can do all of this with Gigo experiment kits.

With every single experiment, they grow smarter and more knowledgeable.

— Before beginning the experiments, read through the instructions along with your child, discuss the safety notes, and keep them on hand for reference. In the complex setup and experiment process, please accompany your child with help and suggestions all steps. This product contains very small parts, be careful not to lose any parts.

— If your children are working on the table, please give them a work mat to protect the furniture.

— Water is an essential part of this product, and none of the models work properly without water. Water is sprayed from a small nozzle in most experiments. Make sure that your child only experiments in humid places, such as bathroom, or outside of course.

— If your child wants to test the model in outdoor territorial waters, please make sure to have an adult accompanied.

We hope you and your child have lots of fun in water power.

Have Fun!

— Water Car EXPERIMENT

1

You will need Your water car, some water and a route that can get wet.

Here's how 1. Remove the PLASTIC BOTTLE from the model, fill it with half of water and put it back.

When installing, make sure that the 80mm TUBE B is bent so that it could touches the lower wall of the bottle.

2. Apply pressure 50 to 60 times to build pressure in the bottle.

3. Place the model on a firm surface route that can get wet, and then remove the RELEASE CLIP from the model. The mixture of air and water will be poured out of the back and the car will shoot forward.

4. Now repeat the experiment without filling the bottle with water.

What is the effect?

2

W H AT ' S H A PPENING? After removing the RELEASE CLIP, the air/water mixture will escape from the nozzle in high speed and the model will shoot forward. On the next page, you will find the reason for this situation and why the car can barely move forward when there is only air in the PLASTIC

Ti p 80mm TUBE B touches the lower inner wall of the PLASTIC BOTTLE. Otherwise, only air may escape from the nozzle. If air or water effluences from the bottle, check that the OD15.8 FLAT O-RING is properly seated and the PLASTIC BOTTLE is tightened.

CHECK IT OUT

— You may have experienced the power supply of car models in your daily life. If you inflate a balloon and leave hold of, the balloon will fly around the room.

Because of the air pressure inside the inflatable balloon is more than the outside air pressure, and this phenomenon is caused by trying to balance the pressure difference between inside and outside.

As long as you close the opening of the balloon, the internal air will press against the elastic outer wall. Once you leave hold of the balloon, the air will flow out of the balloon at a very high speed.

The same thing happens to your car. ?

— The discharged air will produce a reaction force of the same magnitude, and the reaction force is opposite to the direction in which the air is discharged. Therefore, when air is discharged from the back of the balloon, the balloon will accelerate in the opposite direction.

You will need Your PLASTIC BOTTLE with LITTLE AIR WATER SET, marshmallows, a piece of soft toast, and a solid object like a cube

Here's how 1. Cut a small piece of marshmallow and put it in the PLASTIC BOTTLE (Get help from adults). Assemble the PLASTIC BOTTLE and LITTLE AIR WATER SET together and put the RELEASE CLIP on the nozzle.

Now pumping about 80 times. Check the marshmallows. Has it changed? Then remove the RELEASE CLIP and see what happens.

2. Repeat the experiment. This time, put the cube, marble or similar solid into the PLASTIC BOTTLE.

3. Now repeat the experiment again, this time, put a piece of soft toast into the PLASTIC BOTTLE. 4. Then wash the PLASTIC BOTTLE.

3

W H AT ' S H A PPENING? The more air pumped into the PLASTIC BOTTLE, the smaller the marshmallow. When you open the RELEASE CLIP, it will expand again until it returns originally. This is very similar to the air you pump into the LITTLE AIR WATER SET. The more water is pumped, the higher the degree of compression.

On the other hand, cubes or marbles presents like water. No matter how often you pump, they will not change shape and size. Although the toast is soft, it does not change its shape. Because it is breathable, the pressure inside and outside the toast increases evenly.

You will need Your sports car, some water and a route that can get wet.

Here's how 1. Repeat the experiment 1 steps 1 to 3 (page 8).

2. Now try different amounts of water in your PLASTIC BOTTLE. What effect does it have on the range and speed of the sports car? Write the result in the table.

Estimated speed (slow/medium/fast)

2

W H AT ' S H A PPENING? When you fill the PLASTIC BOTTLE with 2/5 to 3/5 (60-90 ml), you will find that your car is driving the fastest and the longest. Obviously, the reason is: If the bottle is out of space, the thrust of the water will be exhausted quickly, only the air will flow out of the nozzle, and the car will not drive away (see page 9). On the other hand, if you fill most or all of the bottle with water, you can only inject a small amount of air into the bottle. This will quickly equalize the pressure in the bottle. However, if the bottle is not overpressured, it will not produce propulsion.

— As you learned in previous experiments and described on

in Nature Technolo and gy

page 9 of these instructions, the loop principle is often used in nature and technology. Where and how can you find these two pages.

IN

SPACE

— To date, practically all rockets are propelled by recoil. This is because other types of propulsion, such as jet engines, would not work at all in space.

Because these suck in air, compress it and expel it again at great speed. That would not work in space, because there is a vacuum there, so there is no air to suck in. On the other hand, rocket drives have everything they need for propulsion on board. A substance is burned inside the rocket

and pressed out of a nozzle at high pressure.

Rockets are of course a little more complicated, but work on the same principle as your water power models.

round G e O n th

— Long before humanity explored space, rocket propulsion systems were built into cars - in the pursuit of new speed records. The first trip of a rocket car was held in 1928 in Germany. Since then, more powerful rocket engines are always installed in cars. In 1997, the rocket car ThrustSSC reached a speed of 1,228 km / hr, that was the first car which went faster than the speed ​​of sound. This car doesn't look like a car, it's closer to the appearance of a rocket. It is 16 meters long, 3.7 meters wide and weighs 10 tons.

Then, they press the water at high pressure through a nozzle - just like your models, the resulting re-

Plant World — There are also some plants that adopt the recoil principle. It's not to move the plant itself, it's spread own seeds in other ways as much as possible, such as the rather inconspicuous peat moss. When their seeds mature, they create overpressure in the capsule. If the pressure is too great, they will explode. In this way, the plant successfully accelerates the spreading seeds speed up to 130 km/hr. Thus, shooting the seeds high enough to prevent the disturbing from wind, and they can transport continuously.

This type of water gun was invented by the American Lonnie Johnson and launched in 1991 under the name Super Soaker. Johnson is actually an air and space technician and did research on a new type of heat pump in the 1980s. When he tried these out in his bathroom, he found that his invention would make an excellent water gun. Then expand its history‌

cal devices. One then speaks in the technical language of “PNEUMATIC” , which comes from the Greek and means something like “breath” or “wind” .

— PNEUMATIC SYSTEMS work with compressed air that is generated by compressors. Electrically controlled valves direct the compressed air into cylinders, the pistons of which then execute the required movement. However, compressed air can't exert too much force. As you have already learned, air has the property of being compressed. The advantage of pneumatics is that has very high working speeds can be achieved and compressed air can be controlled very well. In addition, such systems will not overload.

— You have certainly seen or heard - a pneumatic hammer.

— The PNEUMATIC has wide range of applications. Often it sounds horrible like with PNEUMATIC HAMMER. But it can also sound very nice, like ORGANS, where compressed air creates the sound together with the organ pipes. Sometimes compressed air
