- The STS-124 rocket lifts off with a powerful blast. (NASA courtesy photo) Rockets are vehicles that obtain their forward thrust from a reaction engine.
- Rockets eject mass backward at high speed to achieve a forward push. Did a firefighter ever let you squirt water out of his fire hose? If so, you probably experienced the same thing.
- Water being squirted out of a water hose at high speed creates a strong push in the opposite direction on the hose and on the person(s) holding the hose.
- As you add air to a water bottle, pressure will build up inside. As a result, the plastic walls and the liquid inside the bottle will feel a bigger push.

Soda bottle rockets are a safe and fun way to get into rocketry. If you want to discover what makes rockets fly, this is an activity for you. You can even add different features, like fins, a nose cone, and a parachute to find out how these alter the flight! Try it out!
Aquapod® bottle launcher, like the water bottle launcheravailable from Amazon.com.Open outdoor space in which to launch your rocketSoda bottle (2-L), emptied and cleanedWater (2 gallons)When you cranked up the pressure inside the bottle from 20 psi to 40 psi, your rocket probably reached a higher altitude. By adding fins—even small fins—you probably noticed the rocket took a straighter path to its highest point (the apogee), and no longer tumbled down, but flew straight down. By adding a pointy, sleek nose cone, you made the rocke...
Rockets are vehicles that obtain their forward thrust—the force that pushes the rocket forward—from a reaction engine. In other words, rockets push themselves forward by ejecting mass (that shoots backward) at high speed from their rear end. This mechanism does not rely on the atmosphere and works very well in space. Did a firefighter ever let you ...

Bottle Blast Off. Ready for liftoff? Build your own rocket launcher! Experiment with rocket designs and a PVC launcher to discover how high—and how far—you can make your rockets go. Tools and Materials. For the launcher: Two empty 2-liter soda bottles (one is for the launcher; the other is a spare)
Mar 24, 2019 · This awesome bottle rocket is easy to make, powered by a baking soda and vinegar reaction, and demonstrates Newton's 3rd Law of Motion! Science for kids!
Dec 5, 2020 · Design and build a water bottle rocket that flies straight and in the desired direction. Explain center of drag, and center of mass, and draw their relationships to each other for a straight-flying rocket. Explain why water is more effective than air for propelling bottle rockets.
