How To Make A Bottle Rocket More Aerodynamic
Water rockets are used in schools to help students understand the principles of aeronautics. If there is any sideways motion then the air striking the fins pushes the rocket back towards straight motion.

Air flows smoothly past them if the rocket is traveling along its axis.
How to make a bottle rocket more aerodynamic. One way to make your rocket fly higher is to make it more aerodynamic by using a rounded nose. Adding fins to bottle rockets or any rocket for that matter contributes to the stability of the rocket in flight. Generally aerodynamic rockets have a more stable flight track and can reach a higher apogee.
Drinks bottle which has had a nose cone and some fins added. If you use a rounded nose your rocked should be able to cut through air molecules a little better and experience less drag on the way up. Heres some extra things to think about so you can adapt the.
Also if you have payload on your rocket or a parachute mechanism this is probably where it will be placed. Now draw two concentric circles on the cardboard one slightly smaller than your discarded circle of bottle plastic and one slightly larger than it. Rockets with a large diameter have more drag because their is more air being pushed out of the way.
When the paper towel dissolves the baking soda will be released. The baking soda will react with the lemon juice cause gas to be released quickly and will pop the cork into the air like a rocket. Newtons laws of motion explained that air pressure and water pressure are the two components which make a water bottle rocket fly.
Making a rocket as narrow as possible is the best way to reduce drag. As speed doubles drag increases 4 times as much. Try out making a Paper Rocket Launcher with our latest How To inspiration.
The nose cone The job of the nose cone is to make the rather snub-nosed end of the fizzy drinks bottle more aerodynamic. Clicking on this button displays the slide alone without the captions. Make your bottle rocket more aerodynamic by adding a top also called a nose cone.
The Science Olympiads provide challenges of bottle rocket design and flight including altitudes and distances reached. Watch the video through a few times to get the hang of the activity. The rocket experiences the same force but in the opposite direction which is upward.
Another benefit to using a rounded nose id that it helps to protect your parachute. The fins help the rocket keep pointing in the direction it launched. The corner of a milk carton a tip made from milk carton cardboard and tape or the upper part of a second soda bottle can all serve as nose cone for your basic water bottle rocket as shown in the figures.
This force is what makes a water bottle rocket. Take the pieces of cardboard box and mark out four matching fin shapes. Check this awesome video of how the bottle rocket launcher is operated plus some awesome footage of the launching and the whole process.
Many interesting designs and additional information on bottle rockets can be found with a simple Web search. When a rocket is flying through the air changes in the air can make the rocket wobble. As an aid to teachers we have organized the activities by grade level K-6 4-6 6-8 9-12 11-12 using color-coded buttons.
Place the half-filled bottle onto the ground slip the paper towel pouch into the bottle and place the cork into the opening of the bottle quickly. In this video we explore the power of flight with a simple paper rocket launcher that you can make at home with every day materials. As a further teaching aid you can download your own copy of any slide by using the blue Show Slide button located at the bottom of each page.
The fins Others might disagree but I think. Make your rocket aerodynamic Now to make sure your rocket is built for speed. The size shape and number of fins will change things like your rockets center of mass and how much drag it faces when it flies.
