INTRODUCTION. A water rocket is a type of model rocket using water as its reaction mass. The water is forced out by a pressurized gas, typically compressed air. Like all rocket engines, it operates on the principle of Newton’s third law of motion. Water rocket hobbyists typically use one or more plastic soft drink bottle as the rocket's pressure vessel. A variety of designs are possible including multi-stage rockets..
CONCEPT. Water rocket works based on a simple physics concept in which water is forced out the bottom of the rocket by air pressure, and in doing so exerts an upward force pushing up on the rocket following the Newton's third law. This upward force causes the rocket to shoot upward at high speed. The way a water rocket works is by filling it up partially with water and then pressurizing the inside with air. When the bottom nozzle is opened the internal air pressure forces the water out of this nozzle at high speed causing the rocket to shoot straight up at high speed..

HOW TO MAKE A ROCKET. Cut off the cap end of one of the bottles..
Bottle merge. Take the cut bottle from the previous step and insert it directly over the bottom of the other bottle - this becomes the nose cone of the rocket. Try your best to keep everything straight. If you put the nose on crooked, your rocket will fly crooked..
Take thin cardboard and cut out 3-4 triangles.. These will be the fins of your rocket, so try to cut them at perfect right angles. This way, they will hold the two bottle rocket straight and make sure it coasts smoothly..
CONCLUSION. Roket air yang dilancarkan memerlukan tekanan udara yang sangat tinggi untuk melepaskan roket ke udara . Apabila roket kekurangan tekanan , lancaran roket yang dihasilkan tidak akan memuaskan . Kon yang digunakan pada bahagian atas roket perlu seimbang supaya roket bergerak lurus dan tepat pada sasaran . Fin juga memainkan peranan penting . Fin tidak boleh terlalu besar kerana akan memberatkan roket pada bahagian bawah dan berkemungkinan tidak akan terlancar dengan baik . Tanah liat yang dimasukkan ke bahagian muncung roket juga tidak perlu terlalu banyak supaya roket tidak terjatuh ke hadapan semasa dilancarkan kerana terlalu berat ..
