Holidays are a busy time of Kru bie have good things come to bring a bottle asal badiee of soda. Artificial Water Rocket The lecturer who specializes You Capital One Bang Rak Honor to introduce Mr. geotechnical Taweekul a bottle rocket, a simple but effective. The experiment can be used to shoot a long shot at Crown College School football field. Chiang Mai We first came to know of the bottle before Hrwh bottle PET (Poly Ethylene Terephthalate): PET bottles has become known in the industry, from the soft drink itself. By the bottle that is used to put the drink. It also features a lightweight. The ability of low gas permeability. More important is the impact resistance as well. If we were to use other types of plastic bottles. Which are resistant to low air pressure. When we put pressure on it, it makes a water bottle asal badiee rocket fire bottle rockets explode artificial 1. Prepare asal badiee the device. 2 bottles of 1 liter soda bottles, scissors, tape, or a router. asal badiee Plastic sheet or index futures. Furthermore, clay or paper to clutter rocket harder. And markers to mark the area to be cut. May be prepared wooden cutting 2. Use the marker to cut the limit for one bottle. In order to use the rocket and the rocket skirt called the Fin (FIN) as in the picture may be cut along the top and bottom of the bottle, asal badiee the bottle shape was 3. The header of the first bottle asal badiee (no. 1-1) and put the end of the second to make a bottle rocket. asal badiee May clutter the hard clay was pressed into the header. Then stuck together with tape wrapped tightly 4. Connect the other end of the bottle to make a skirt and fin with tape 5. Decorate as desired. This method may be adapted to decorate a result of the shooting. Because what is involved in the shooting asal badiee is related to the shape and weight of the rocket's fins or the air resistance asal badiee 6. Add water and mounted on a base hit. By inflating a pressure of 50 pounds per square inch. The pressure to make a very long shot for shot at the schoolyard. Cautions Due bottle rockets are dangerous due to high pressure. And fell to the floor Rockets asal badiee can be dangerous Should be careful 1. The activity must be in the open air. There are people roaming around like a football field 2. The materials used to make bottle rockets. To perform a pressure test to know the exact value in order to secure the bottle (bottle PET) can withstand asal badiee pressures up to 12 bar 3. The activities. Participants must wear protective equipment such as helmets and head protection potential glasses and raincoat 4. Before launching a water bottle. Must first make sure that every time someone in the area that could be dangerous or not, and tending asal badiee to the direction of the rocket must not ethnicity 5. If the action is. Requiring adults to advise and supervise the activities of the Water Rocket 1. Always use a variety of learning activities, scientific 2. To promote scientific skills to those activities 3. 4. Further work is needed. activities include the scientific knowledge into action 5. Can integrate several subjects. Suggestions to be used in schools. Because the water rocket science through activities that require a base hit, a major equipment is indispensable. It has been suggested that the school should be purchased or made available to students. To make science asal badiee learning through play water bottle rocket out of it completely, the rest of the bottle rocket.
2. wing / fin Bottle Rocket (Fin): an important part in the direction of the rocket bottle rocket 3. Water: the shape of the bottle rocket that affect the resistance (drag) and the position of the center. of resistance (center of drag) and rocket design bottle must appealing coverage of bottle rockets and the rocket bottle to smash also has components that we need to learn, whether as a stand. Bottle Rocket Bottle water pump mathematical model of bottle asal badiee rockets, asal badiee etc., which can be learned from books, websites or exchange experiences bottle asal badiee rockets directly from those who have a deep interest in the activity. asal badiee Invention Water Rocket By Occasion asal badiee Learning science through water bottle water rocket asal badiee propellant is one that is designed to enable students to learn the scientific process and scientific skills. And to raise awareness about science to students in another way, through the actual implementation. Water Rocket Science asal badiee We explain the rise of the water bottle rocket with scientific theory, however. You've seen Bottle rockets shot up into the air. But few people know why. It is up to the engine when it is not. Or the ignition of the fuel itself. We can explain the rise of the water bottle rocket with Newton's laws of motion. asal badiee Which was invented by Sir Isaac Newton, the English scientist Rule 1 is called the "law of inertia", ie no external force on the object. To maintain the movement of it. By moving the same direction With the same speed as if the ball is placed.
