Rockets capture the imaginations of adults and children alike. Unfortunately, we often refer to “rocket science” as if it is the most complicated subject on the planet. While some highly advanced rockets are engineered with extreme precision, you can still make very simple rockets at home. There are several ways to make a homemade rocket from launching matches to shooting off water rockets.

Building a Match Rocket

  1. Put two matches on aluminum foil with the plain ends sticking out and the match tips pointing in. Roll the matches up like a burrito. Twist one end of the foil tightly around a match and leave the other end rolled loosely. [1]

    Stick the matchstick of the tightly rolled match into a piece of cardboard. This will hold that match in place. Being anchored in the cardboard also allows you to aim the match and launch in whatever direction you choose. [2]

    Use a candle or lighter to heat the foil. Put the flame directly under the area of foil that conceals the match heads. When the matches get hot enough, they will ignite. This bb will send the loose match shooting out of the aluminum holder. [3]
    • When the match heads ignite, gas is rapidly formed and this expanding gas forces the loose match out of the aluminum holder with a considerable amount of force.

Launching a Rocket with Water and Air

  1. The body of your rocket will be made from a plastic water bottle, a paper cone, and two paper or cardboard triangles. [4] You will use three pencils to make a stand. You will also need a cork, water, and a bicycle pump to pressurize the bottle.
  2. Watermark wikiHow to Make a Simple Rocket
    Make a rocket from a bottle. Reduce the drag of the water bottle by taping a paper cone to the top of the rocket (the bottom of the bottle). Tape paper or cardboard triangles on either side of the bottle to act as fins. [5] The triangles should come about halfway up the bottle.
  3. Watermark wikiHow to Make a Simple Rocket
    Tape pencils around the sides of the bottle to make a stand. Make sure that the pencils are pointing down. This stand will allow you to point your rocket up (or at an angle if you wish). [6] Without a stand, your rocket will likely just flail around near the ground instead of lifting off.
  4. Watermark wikiHow to Make a Simple Rocket
    You should fill the bottle half full of water. The water will provide the mass needed to propel the rocket during the launch. You can add food coloring for a colorful blast off.
  5. Throw away the bottle’s original cap and replace it with a cork that fits into the opening of the bottle. The cork will allow pressure to build inside the bottle. [7] The cork will also pop out allowing the contents to shoot out rapidly and propel the bottle.
  6. Use a bicycle pump with a needle. Insert the needle into the bottle through the cork and pump. Once enough air has been pumped into the bottle, the pressure will force the cork out and launch the rocket into the air.

  1. Watermark wikiHow to Make a Simple Rocket
    Make sure that the ends of the pencils come up past the top of the bottle. This will ensure that they touch the ground when the bottle is upside down. The pencils will allow you to stand the bottle up on its top.
  2. Watermark wikiHow to Make a Simple Rocket
    Put two tablespoons of baking soda in a tissue and roll it up. Make sure that the sides are folded over so that no baking soda is exposed. This will provide a time delay on the very rapid vinegar and baking soda reaction.
  3. Watermark wikiHow to Make a Simple Rocket
    Use a funnel to fill the bottle with vinegar. The vinegar is acidic and will react with the basic baking soda to neutralize. Carbon dioxide will be produced in this reaction, which will cause pressure to build inside the bottle.
  4. Drop the baking soda packet into the vinegar. From this point forward, you will need to move quickly. The tissue will unravel quickly. The reaction will start as soon as the baking soda comes in contact with the vinegar.
  5. Watermark wikiHow to Make a Simple Rocket
    Quickly place the cork in the opening of the bottle. This will prevent gasses from leaving the bottle and cause pressure to build. With the cork in, set the bottle upside down on the pencils.
  6. Watermark wikiHow to Make a Simple Rocket
    As the tissue unravels and the baking soda and vinegar react, more and more gas will build inside the bottle. This will force the cork out from the bottom of the rocket. That force will propel the rocket off of the ground and into the air.

  • Question
    To increase distance, do I add more vinegar or baking soda or both?
    Community Answer
    Just put 50% vinegar and 50% baking soda. Both should be equal in volume.

  • Question
    How far will the rocket go if I utilize the method of baking soda and vinegar?
    Community Answer
    It will probably go 2-10 meters up, depending on how much fuel you have. Remember to wear safety goggles so you do not damage your eyes.

  • Question
    How can the acceleration of the rocket be increased?
    Startrekker
    Community Answer
    Acceleration of the rocket can be increased by (any of the following): Increasing the velocity of the exhaust. Decreasing the dry mass of the rocket. Burning propellant at a faster rate. in solid rockets, this is done by using appropriate grain geometry. simply, increase the area of the propellant so that it burns faster.

      About This Article

      Article Summary X

      To make a simple match rocket, first roll 2 matches in a small piece of aluminum foil so the match tops are covered and the sticks are poking out at the end. Then, twist the end of the foil closed near the match tips and leave the other end rolled loosely. Once your matchsticks are wrapped, anchor them by stabbing them into a piece of cardboard so they stand up on their own. Finally, hold a lighter under the part of the foil that holds the match tips. When they get hot enough, the matchsticks will rocket out of their aluminum holder! To learn how to make a rocket with baking soda, read on!
