Because the bottles have the same circumference it will be a tight fit. Use scissors to cut along the line until you remove the bottom portion of the bottle. Find the line in the plastic where the factory joined the bottom of the bottle to the main cylinder. Now that you've set your BOTTOM BOTTLE off to the side and PROMISE YOU WILL NOT CUT INTO IT, gather your remaining bottles. For information on user permissions, please read our Terms of Service.

Step 9: Launchers
Scientists use several units to quantify pressure, but it is mostly commonly expressed in pounds per square inch (psi) on your bicycle pump. Did a firefighter ever let you squirt water out of his fire hose? As the water squirts out at a high speed, the hose (and the person holding it) experience a strong push backwards.
Many thanks to RESOURCE fellows Travis Smith and Eric Anderson, and Matsuyama Elementary School sixth-grade MESA students Bobby Horst and Godebo Chapman. These activities are designed to be carried out by children working with a parent, guardian or other appropriate adult. The adult involved is fully responsible for ensuring that the activities are carried out safely. NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery.
After groups have filled out the Revised Design Worksheet and made sketches of their rocket designs, conduct rocket trials to test the four different design ideas (Table 1). Conduct the rocket trials as a class demo using the two-liter bottle rocket created by the teacher in advance. The trials are the testing step of the engineering design process, so expect students to make observations and record the test results. The key to water bottle rocket flight stability is the physical separation, along the length of the rocket, of the center of drag (COD) and the center of mass (COM). The COD is the point at which a pivot is placed on a wind vane in order to prevent it from turning one way or the other. A normally functioning wind vane does NOT have its pivot point at the center of drag, which is why it indicates the wind direction.

Groups of students can work together with a teacher to learn the fundamentals. In the figure at the top of this page, we show teachers and students from two different schools involved with bottle rocket activities. The center photo comes from Sue Simmons of Birche’s Elementary School in Turnersville, New Jersey. Mrs. Simmons and her students are preparing a rocket for launch at the pad. The other two photos are from Casey Teliczan of the Rockford Public School District in Rockford, Michigan. Mr. Teliczan’s activities are part of the Rockford Community Services after-school enrichment program.

So buckle up and prepare for an adventure of a lifetime as we unlock the secrets to designing and launching the most epic 2-liter bottle rockets the world has ever seen. The two-liter bottle rockets that students will create later in the activity can be launched with all air or an air/water mix (some water added to the two-liter bottle pressure vessel). This simple mini-activity illustrates why water is a more effective propellant than air. Expect rocket designs to be nearly identical for distance and hang time, except for hang time rockets that add parachutes. The experiment is based on Newton’s 3rd law that states every action has an equal and opposite reaction. When air is pumped inside the bottle air pressure builds up and that increases the water pressure forcing it to come out downwards.
So grab a 2-Liter bottle, gather your supplies, and get ready to ignite your creativity and master the art of 2-Liter bottle rockets like never before. Parachutes are used to slow down the fall of a rocket to reduce the risk of damaging the rocket as it touches the ground. For a bottle rocket, air resistance has to knock off the nose cone, causing the suspension lines to unravel and the parachute to unfold. This takes time, so if your rocket does not reach enough altitude, your parachute might not have enough time to open up and do its job. Some design changes, like shorter suspension lines, lightweight material, and neat folding techniques, can help speed up the deployment of your parachute.
Air pressure, or how hard the air presses outward on the inside of the bottle, builds up in the bottle and you might even see the bottle bulge out a little. A water rocket is propelled by pressurised air forcing water down though a nozzle. The rocket will only go 50 feet more because of the added mass. A two stage rocket will work better because it would not have to carry the full payload on all of its flight. When it comes to choosing the best 2-liter bottle for a bottle rocket, durability is key.
The hinge is mounted on the pipe clamp.4.when you slide the bottle on (use vaseline to seal it) make sure the pipe clamp is right next to the neck on the first stage. This will have your hinge on, next clip your hinge onto the bottle neck so it is tight and won't fall off. This bottle will serve as the bottom of your rocket and must hold the water and air pressure. Even the slightest pinhole in this bottle will cause the rocket to fail. Remove the label and set the BOTTOM BOTTLE off to the side. A basic understanding of energy and energy transfer; forces, mass and Newton’s laws of motion, velocity and acceleration; drag (air resistance); and levers.
You can use an online calculator, like this one to make the conversion between pounds per square inch and pascals. As the water squirts out at a high speed, the hose (and the person holding it) feels a strong push backwards. Note the push is in the opposite direction of the water flow.
Students are challenged to use two-liter plastic soda bottles to build water bottle rockets that travel the furthest distance or can hang in the air the longest (hang time). They follow the steps of the engineering design process as they create rockets using plastic bottles, paper or plastic sheet material for fins, and tape. Get ready to witness the awe-inspiring spectacle of 2-liter bottle rockets as they defy gravity and soar to new heights. These exhilarating rockets, powered by a unique combination of water and air pressure, unleash an explosive burst of energy that propels them into the sky with astonishing speed.
