What kind of pressure is showing to be most effective in making the rocket go farther? During the Experiment Are the weather conditions affecting the rocket launcher? This answer depends on the scientist, but weather conditions will affect how well your rocket flies. What is the purpose of the fins on the rocket? The fins stabilize the rocket and allow it to fly in the right direction without wobbling or rolling. What does the nose cone do for the rocket? The nose cone helps reduce the air resistance that pushes against the front of the rocket. WARNING: Before trying any launches, make sure your rocket is facing in a safe direction away from people and fragile objects!ĭiscovery Questions Beginning the Experiment How do rockets get into the sky? If there is a force (thrust) that can overcome the weight of the rocket and the drag on the rocket, we have liftoff! This force is usually produced by burning a fuel or, in this case, air pressure. (Curved connectors do not need to be taped.) (Not using the connectors may cause the air pressure to leak, leading to a slower launch of your rocket.) Once everything in your design is finished, duct tape all straight connectors to ensure your design is airtight. When connecting the different pipes in your launcher design together, use the PVC pipe connectors.You can use our original rocket-making instructions to make the rockets for your launcher, or try to vary the shape and size of the nose cone and fins to see if these factors impact your rockets’ flying ability!.How many rockets do you want to launch? (We suggest using one 2-Liter bottle per rocket.) Do you want to launch your rocket at an incline? (Tip: Use a PVC Pipe connector to do this.) Do you have enough of each material to make your launcher and all the rockets you will need?.There isn’t a straightforward process for this since you can use your own ideas and creativity to come up with the exact design for your super duper rocket launcher! We have a few suggestions and guidelines below to help guide your thinking: Consider the following questions when brainstorming the design for your multi-rocket launcher:
Your rocket and rocket launcher are ready! Apply pressure to the 2-Liter bottle to launch your rocket! You can squeeze it, jump on it, or create a giant rocket launcher with your friends! (WARNING: AIM THE ROCKET AWAY FROM ALL PEOPLE PRESENT TO ENSURE NO ONE GETS HURT.)Įxperiment Extensions Try Making a Multi-Rocket Launcher:.(Be sure to blow air into your 2-liter to maximize air pressure before taping it to your rocket.) Secure this end to the bottle with duct tape. Place the other end of the PVC pipe section inside your 2-liter bottle.
Using a pencil and a ruler, draw 3-4 triangles or “fins” of exactly the same size and cut them out.Attach the cone to the end of the rocket body with duct tape.Twist the remaining piece into a cone and fasten the side with scotch tape.Cut out a section of approximately 90 degrees from the circle.Using scissors, carefully cut a circle (5 – 7” in diameter) from the construction paper.(Adult supervision required.) You will only need one 6” section for the body of each rocket you make. Cut ¾-inch pipe insulation into 6” sections.
