The Bottle Rockets

What we did for our project was create water bottle rockets. What I all learned from making water bottle rockets was really interesting. We figured out that the smaller the rocket is, the farther it will go. The reason it will go farther is because it has less weight on it, although some big rockets will go pretty far too. What I did for my rocket was get one 1-liter bottle and cut out four triangular cardboard fins. After doing that, I hot-glued the fins towards the bottom of the rocket. When I was finished with that, I got another 1-liter bottle ad cut it in half so I would have the nose of the rocket. I used the pointed half of the bottle because a pointed nose works better than a flat nose. I put the nose on the rocket and duct-taped it…

from the experimental data, that the relationship between the difference in initial pressure inside the bottle rocket and the atmosphere, and the vertical height reached by the bottle rocket after 0.1 seconds, is proportional. This is quantitatively demonstrated by the high R2 value of 0.99533 of the graphed relationship, which indicates the likeness of points in a data set to an established trend; where 1 = a perfect relationship. The gradient of 0.0236 in the best fit regression line of the…

of bottle rockets can be controlled by a multitude of factors. To understand these factors, mathematics can show us how they interact and how they affect performance. Water Bottle Rockets are mainly used for educational purposes in schools. They are used to explore basic aerodynamics and physics. Water rockets demonstrate many different forces such as weight, thrust, lift, and drag. Basic parts of a common bottle rocket include a nose cone, fins, a base, and a launcher used to launch the…

Rockets are a very important aspect to the world, for they help in making huge discoveries in science and astronomy. Expensive materials, such as aluminum, titanium, and nickel alloy, help make a sturdy rocket. For the bottle rocket, my partner, Maren Cheney, and I used the following materials: 2 plastic 2-liter bottles, office folder paper, clear duct tape, yarn, 2 sponges, and cotton. The payload of the rocket is the object(s) being carried throughout the flight. While the payload of real…

Physics Fair – Bottle Rocket (Introduction, Materials and Method) Introduction A bottle rocket is composed of two elements, energy and fuel. The energy in the case of a bottle rocket is compressed air as it is pumped into a soda bottle, half filled with water by a bicycle pump. Compressed air is an excellent source of energy because it is very lightweight and can store a plentiful amount of energy, also it does not weigh down the rocket. Water is then used as the fuel for the rocket. Water is…

I needed to build a water rocket that would be aerodynamic, light, and have the ability to glide down to elongate flight time. I started out researching different bottle rocket designs to find what would work best. While researching, I found that having a slimmer bottle on top of the base bottle, versus having two regular sized soda bottles would be more aerodynamic and would allow me to give the rocket a more “bullet” shaped body. When looking at fins, those with larger fins worked more…

How Does the Volume of Water Effect the Height of a PET Bottle Rocket? Aim: Investigate how the volume of water affects the maximum height of a PET bottle rocket. Hypothesis: The rocket using 600ml of water will reach the highest altitude due to the golden ratio of air to water. Research: The first rockets originated from China. To be a ‘true rocket’ it needs to be ‘a device operating solely by self-propulsion’ according to the Smithsonian Museum. Some researchers discovered that the first…

Bottle Rocket Background Paper A rocket is a vehicle that can travel through the air really high and can contain things like water, air, fireworks, signals, flares, etc… The water and air are pushed on the ground (which pushes the rocket up) when the rocket launches. This is called thrust. Thrust is created by Newton’s third law of motion which is , “For every action, there is an equal and opposite reaction.” In this case, the action is the water and air pushing on the ground. The equal and…

Building bottle rockets can be a fun and learning experience, as many students at UCAS found out. There were many things to test, and many interesting aspects of the rocket. Three main features of the “Mission to Mars” are how to construct the rocket, rocket performance, and physics of the rocket. When these items are viewed, it is evident that students can see the effects of physics in real life problems. And by doing so become more intelligent as teenagers want to learn more, and have fun…

Aim: To use a neutralization reaction to propel a model rocket. Hypothesis: That the neutralization reaction between the bicarbonate of soda and the vinegar will produce a gas, which build up enough pressure to launch the bottle rocket. Materials: Vinegar, bicarbonate of soda (NaHCO3) Equipment: Plastic Bottle, Wooden Block, Nail, Cork, Duct Tape. Method: 1. Nailed a cork to plank of wood as a base for the rocket. 2. Wrapped tape around cork so that it fitted the neck of the bottle. 3. Put two…
