Equation for Water Bottle Rocketīelow is an equation that connects all the variables and constants of the system. The law of conservation of the momentum holds as the upward momentum of the rocket is equal but opposite of the momentum of the escaping water. It falls back to the earth due to gravity. Note that the weight of the rocket constantly changes during flight. It is this reaction that forces the water bottle rocket up. If this force is termed as action, then the water should exert an equal and opposite reaction in the upward direction. When air is pumped inside the bottle air pressure builds up and that increases the water pressure forcing it to come out downwards. The experiment is based on Newton’s 3 rd law that states every action has an equal and opposite reaction. It allows the rocket to glide to the earth avoiding severe damage to its parts. It would be best to have large wings or fins that are close to the center of gravity. Mark the thread just before it starts descending and measure the height. The thread should be laid flat on the ground so that the rocket takes it along as it gains altitude. To calculate the height attained by your homemade rocket, attach a long length of sewing thread to the tail of the rocket.The center of pressure must be located below the center of gravity for stability.To increase stability, you can add more mass near the nose cone of the rocket so that the center of mass is shifted towards the nose cone end.Larger rockets or those with a large volume should be built lighter whereas smaller lighter ones should be given some extra weight in order to fly higher. It is important to maintain an optimum weight.Water Bottle Rocket Nose Cone Template Tips You will get more ideas from the below diagrams. The various parts of a rocket, especially the nose cone, nozzle and fins, need careful designing for aerodynamical grace. A proper introduction, theory, design method, math and sketch are indispensable for the technical report. You can note the trajectory of the system for a vertical launch and launch at an angle in the report. Prepare a neat data sheet with the measurements, calculations, if any and present the lab report if you do the simple activity in school as a lab assignment. The conclusion or result would be that the water bottle rocket could fly. Pump air into the bottle and watch the rocket take off with force.ĭon’t stand too close to the rocket as water would be squirted out in all possible directions.The bottle should be made to stand inverted on its fins.For launching, take the bottle outdoors and connect the pump to the needle adaptor.

Make the bottle a quarter full with water and insert the cork in tightly to close it.Attach the cone to the base of the bottle and the fins to the sides.You might have to trim the cork for this. Pass the needle adaptor through the cork in such a way that it goes all the way through.Piece of cardboard made into a cone and 4 fins.Empty plastic bottle (a 2 liter soda pop bottle would be fine).The water powered bottle rocket flies on pumping in air.
