How to make a baking soda and vinegar rocket

Pour about an inch worth of vinegar into the bottom of the bottle . Put about a teaspoon of baking soda onto the tissue square and fold it up (this will create a time-release packet). This is most definitely an outside project! You can get as messy as you want.

What is the best ratio of baking soda to vinegar for a rocket?

How do you make homemade flying rockets?

Rockets made of baking soda and vinegar are a great chemistry lesson for kids. All you need is baking soda, vinegar, a paper towel, three pencils, some tape, and a plastic soda bottle. This basic chemical reaction can launch the rocket up to 100 feet.

What does vinegar and baking soda create?

When vinegar and baking soda are first mixed together, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda . The result of this initial reaction is two new chemicals: carbonic acid and sodium acetate. The second reaction is a decomposition reaction.

Is baking soda and vinegar harmful?

” Baking soda is basic and vinegar is acidic,” says Bock. “When you put them together you get mostly water and sodium acetate. But really, just mostly water.” Plus, vinegar causes baking soda to foam up. If stored in a closed container, the mixture can explode.

How much co2 does baking soda and vinegar create?

Does baking soda dissolve in water?

Baking soda dissolves readily in water . If water is evaporated from a solution of baking soda , the baking soda is recovered unchanged; thus, solubility is a physical property.

How much vinegar and baking soda do you put in a volcano?

1 tbsp bicarbonate of soda ( baking soda ) 1 tbsp washing up liquid. 2 tbsp water. ½ cup vinegar .

Is making rocket fuel illegal?

Yes. Making model rocket fuel and engines is legal in the United States according to Federal law, but your specific state and local laws may differ. Some of the materials you may want to use to build an engine may require a permit from the Bureau of Alcohol, Tobacco, Firearms, and Explosives.

How high can a homemade rocket go?

Hughes has repeatedly tried to launch homemade rockets and actually did launch an earlier rocket in 2018. During that flight, which reached a maximum height of 1,875 feet (572 m), Hughes suffered compressed vertebrae but still aimed to launch ever higher.

How do you make a mini rocket that can fly?

Cut out your rocket components (cylinder, nose cone, and fins) and glue them together. Open the film canister and drop one-half of an Alka-Seltzer tablet into it. Fill the canister half full of water and snap the canister cap into place. Slide the rocket over the cap, place the assembly cap-down, and get back.

How much baking soda and vinegar do I use?

How to make a baking soda and vinegar rocket

Have you ever watched a spacecraft launch on television or seen one live? One question that may have crossed your mind when watching this awesome spectacle is, “How does a spacecraft lift off and get into space?” The simple answer to this question is that the spacecraft has engines that lift it into space. All rockets depend on combustion to provide the thrust that is required for a vessel to overcome the force of gravity and climb into space.

One well-known spacecraft that you may have seen launch is the National Aeronautics and Space Administration (NASA)’s Space Shuttle, shown in Figure 1 below. The Space Shuttle did operational flights for 30 years, from 1981 to 2011. It had three major components: the orbiter (a winged “space-plane” which held the astronauts and different kinds of payload), the large, dark orange-colored external fuel tank, and two solid rocket boosters. At launch, the two solid rocket boosters, along with the orbiter’s three main engines, would power the liftoff.

Contrary to popular belief, it does not take an explosion to get a spacecraft off of the earth. Rocket engines function on the principle of combustion. Combustion is a fast chemical reaction between a fuel and an oxidizer (such as oxygen) where the fuel is burned or oxidized. Usually the fuel is an organic compound (containing hydrogen and/or carbon, and sometimes even metals). For example, on the Space Shuttle the orbiter’s three main engines used liquid hydrogen as the fuel and liquid oxygen as the oxidizer. However, the Space Shuttle’s two solid rocket boosters used aluminum powder as the fuel and ammonium perchlorate as the oxidizer.

During combustion, new compounds are made and these are called the exhaust. At the same time, a great amount of heat is produced because combustion is an exothermic reaction (it makes energy, in the form of heat and/or light). Altogether, the combustion in the spacecraft’s rockets produces great amounts of exhaust gas at high temperatures and pressure. The pressurized hot gases are pushed out from the bottom of the rocket and thus, the spacecraft is thrust upward. This is an example of Isaac Newton’s third law of motion, which states that for every action, there is an equal and opposite reaction.

Mixing the fuel and oxidizer together correctly is complicated and something that real rocket scientists work hard to perfect. In this chemistry science fair project, you will become a rocket scientist, but instead of using rocket fuel and oxidizers, you will use baking soda (sodium bicarbonate, or NaHCO3) and vinegar (acetic acid, or CH3COOH) to make a different kind of chemical reaction that can launch a small-scale rocket. This reaction is shown in Equation 1 below. Based on acid/base chemistry, the reaction produces water (H2O) and carbon dioxide (CO2). (You do not need to know acid/base chemistry to do this science project, but if you want to learn more about it, you can check out the Science Buddies resource Acids, Bases, & the pH Scale.) Carbon dioxide is what makes soda fizzy and bubbly, which is why you see lots of bubbling and foaming when you mix baking soda and vinegar together. You will mix baking soda and vinegar in a capped film canister and take advantage of the pressure the carbon dioxide gas creates in the canister to launch your own small-scale rocket. When the pressure (or force being exerted against the inside of the canister by the carbon dioxide gas) is great enough, the canister’s lid will pop open and the rocket will launch. How will different amounts of baking soda and vinegar affect the launch height? While trying to answer this question you might not be launching the Space Shuttle, but you will still have messy fun escaping the force of gravity for a few seconds with your own rocket!

Big Idea
Everyday kitchen items can be used to create simple chemical reactions.


  • Empty plastic bottle
  • Duct tape
  • Cork that fits the bottle
  • Toilet paper or tissue paper
  • 3 pencils/pens (for tripod)
  • Vinegar
  • Scissors
  • Funnel
  • Baking Soda

At a table lined with newspaper, set out the empty plastic bottle, 3 pencils or 3 pens, and duct tape.


    1) Begin by creating your rocket. Use an empty plastic bottle, three pencils or pens and duct tape. Make sure that your bottle is corked and standing on the three pencils or pens creating a tripod.
    2) Next, step is creating the rocket fuel or baking soda packets. Cut a square piece of toilet paper or ½ piece of tissue then put 1 scoop of Baking Soda in the middle and roll it together tight. Be sure to twist the ends of the toilet paper or tissue so it will fit inside the opening of the bottle. Make several baking soda packets.
    3) Go outside to an open area about six feet away from buildings or cars and find a flat, safe launching “pad”. Set up a video recorder so you can record your rocket launch (and send your results back to KCM!).
    4) Next, have an adult with safety glasses fill the empty plastic container with vinegar using the funnel.
    5) Very carefully place one of the baking soda packets into the plastic container, put cork on and quickly get away.
    6) Watch what happens. Guess how high you think the rocket will go? How long does it take to happen? When the lid pops off the rocket should launch. This could take several tries. Tip: Make sure your cork is secure and your rocket is standing on the pencils or pens.
    7) Then try changing the amount of baking soda to vinegar ratio. What do you think will happen?

Baking soda and vinegar mix together to create a reaction resulting in water and carbon dioxide gas. The pressure of the carbon dioxide gas forces the cork to pop off and the rocket to launch. This is an example of Newton’s third Law of Motion. When you apply a force in one direction, the opposite equal reaction will take place in the opposite direction.

8) Be good to the earth and rinse away the baking soda and vinegar residue left behind the experiment.

How to make a baking soda and vinegar rocket

How to make a baking soda and vinegar rocket

How to make a baking soda and vinegar rocket

  • baking soda
  • tissue to wrap baking soda in
  • vinegar (can also do with lemon juice)
  • rocket
  • cloth for clean up
  • water to rinse out rocket
  • open site to set off rocket
  • sturdy flat base to stand rocket on if grass is bumpy
  • optional: molecule models – 3 red oxygen atoms, two white hydrogen atoms, one black carbon atom and 6 bonds for each student/student pair

What happens when we mix baking soda and vinegar/something sour? It makes a gas. Baking soda and vinegar in this bottle with the cork on will trap gas in the bottle. The pressure will build up, until it pushes the cork out.
It is a rocket powered by a chemical reaction.

Pour 200ml vinegar into the bottle.
Add a couple of teaspoons of baking soda to the tissue, and twist the ends to package it, but so that it is narrow enough to fit through the mouth of the bottle.
Make sure that you are away from the students, then push the baking soda package into the bottle. Cork the bottle, then stand it up for take off.
Stand back. Even if it takes a little time, the tissue will eventually disintegrate and release the baking soda into the vinegar, and set off the rocket.
If you think gas escapes more slowly (around the side of the cork, for example) and the rocket will not fly, kick it over with your foot before reaching down to take it apart, and reset it.

With older students, model the chemical reaction that powers the rocket:
Give each student a model of HCO3 (baking soda) and H (the atom that makes vinegar acidic). We started with these in the rocket.
The baking soda and vinegar molecules react and rearrange to make two new molecules. Ask students to figure out what these molecules are, giving them the hint that one of them is water.
The products of the reaction are water (H2O) and carbon dioxide (CO2).
Carbon dioxide is a gas, and as more and more of it is made by the chemical reaction, the gas builds up in pressure until it blows the cork out of the bottle.
Once the cork is released, the gas can escape by shooting out of the bottom of the rocket. This force propels the rocket upwards.

A rocket that goes to space acts on the same principal of action and reaction: the exhaust is expelled out of the back of the rocket, and this force is countered by a force on the rocket that propels it upwards.

here is how to easily make a baking soda rocket.

-empty pop bottle -hot glue

-vinegar -wine cap

-Baking soda toilet paper

Step 1: Fin

The first step is to draw the fin of the rocket on some cardboard and to cut them

Step 2: Fin-2

Now glue the fin to an empty pop bottle with hot glue. Make sure all the 3 fin are at the same distance

Step 3: Primer

Now it is time to make the primer of the rocket by means of paper and of Baking soda. It is necessary to roll up the powder in the paper and to close every extremity with the brooch. The brooch has to exceed on one side.

Step 4: Primer

The rocket is ready to launch. you just need to put a bit of vinegar in the bottle and set the primer In the mouth of the bottle so that it does not touch the vinegar.Use the cap and the brooch for this like show on the picture.

Step 5: Launch

Now just turn the bottle upside down and the rocket should go off. If not shake it a little bit. Here is a youtube video of my lunch. You can customize your rocket as you want, make it bigger, put more fin, add decoration.

Rocket Body

  1. Attach a cone to the bottom of a small plastic bottle. The cone will become the tip of the rocket and will help the bottle travel faster. To make one, roll a piece of paper (preferably thick paper or thin cardboard) into a cone, cut the bottom so that it’s even, and tape it to the bottom of the bottle.
    • For extra strength, wrap the cone in electrical tape or duct tape.
  2. Attach fins to the rocket. Cut 3 or 4 triangles out of thin cardboard, bend “tabs” into the sides so that they can easily be taped to the side of the bottle, and attach them around the neck of the bottle (which will be pointing down and is where the fuel will blast from).

Rocket Launcher

  1. Find a tube that fits around the neck of the bottle. A toilet paper or paper towel tube will work in a pinch but probably can’t be used more than once because the cardboard will get soggy when the rocket launches. A more durable option is to use a piece of PVC pipe.
  2. Cut the tube to size. Since it will sit underneath the bottle to hold it up, it should be long enough to keep the mouth of the bottle off the ground but not so long that the rocket doesn’t sit stably inside it.
    • Get an adult to help you cut the PVC pipe if necessary.
  3. Attach the tube to a base. Gluing it to a wide piece of wood will work well.
  4. Place the launcher in a good location. Ideally, place it on a hill (for extra height), on a slight slope (so that the rocket will launch at an angle), and pointing with the wind.

Rocket Fuel

  1. Fill the bottle about 1/4 to 1/3 of the way with vinegar. Any kind/type will work, but white vinegar will make the least mess.
  2. Put baking soda in a time-release container. This will allow you to add the baking soda to the vinegar without having it explode immediately. You will need several large spoonfuls of baking soda to make the rocket powerful. The easiest way to do this is to put baking soda on a square of cling wrap, fold the corners up, and twist the wrap several times to hold the powder. When you put this in the vinegar later, it will unravel slowly.
  3. Prepare a balloon to cover the mouth of the rocket. When the time comes, you’ll need to cover the mouth of the rocket to hold the fuel inside. Of course, you don’t want to cover it so well that nothing comes out. The best way to do this is with a balloon:
    • Cut a piece of balloon that fits over the mouth and neck of the bottle. Make sure it’s big enough to cover the whole neck, but don’t use the whole balloon; save the extra for other launches.
    • With a marker, draw a dot in the center of the piece of balloon.
    • Poke a tiny hole in the center of the dot with a pin. The dot will let you know where the hole is later.
    • Set the balloon aside (along with a rubber band). You’ll need quick access to these when you launch, so don’t lose them.
  4. Carefully put the baking-soda container inside the bottle. Try not to agitate the bottle, which will make the cling wrap unravel faster.
  5. Center the balloon over the mouth of the rocket and secure it around the neck with the rubber band. The dot help you make sure the hole is centered. The hole may drip a bit, but when the rocket launches, it will allow the fuel to shoot out.
  6. Place the rocket on the launcher or stand it up on its fins. Placing fins on your rocket that sit lower than the mouth will allow you to use the fins as a stand. (See Rocket Body below for tips.) If you don’t want to add fins to your rocket, see Rocket Launcher below for design instructions.
    • To make a faster, easier rocket launcher, shove a straight stick / thin piece of wood into the ground (a bamboo skewer might work, tape a narrow tube (a rolled up piece of paper or even a drinking straw might work) to the side of the rocket, and simply slip the tube over the stick to hold the rocket up. Make sure the stick sits firmly in the ground. Insert it at a 45-degree angle if you want the rocket to go farther.
  7. Wait for the rocket to launch. If you’ve made the baking-soda container properly, it should take at least a few seconds for the baking soda to release into and react with the vinegar.
  • Test different amounts of baking soda and vinegar to see what proportions work best.
  • Putting fins on the bottom of your rocket will help keep the center of gravity low and make it spin better. Putting a point on the top will decrease air resistance. See How to Build a Bottle Rocket for more design tips.
  • Don’t get a bottle that is too big or it won’t work. The smaller and lighter the bottle, the better.
  • Use less baking soda and vinegar to make it go higher.
  • Use a vitamin-water bottle (or similar bottle made of thick plastic); since it can take more pressure, it may also go higher.
  • Make sure you stand back before the rocket explodes.
  • If you are a child, get an adult to help you or do it under parental guidance. This is for the safety for you and others around you.


  • Don’t launch the rocket near cars, houses, or other valuables to avoid breaking anything.
  • Never point the rocket towards yourself or anyone else because you can hurt them with this.
  • Stand at least <> away. It may also be a good idea to wear safety goggles too (just in case).
  • You can do the same thing here but with pop and Mentos. Experiment and have competitions with your friends!
  • If the saran wrap does not come undone carefully approach the bottle from the opposite side of the area that the bottle is facing.
  • If you’re holding the rocket, make sure to hold your hand out with the rocket away from your body.

Step #1: Make the rocket body

How to make a baking soda and vinegar rocket

Take the top off of a plastic film canister and wrap a sheet of construction paper around it. Tape it in place so that the open end of the canister sticks out at the bottom.

Step #2: Create the nosecone

How to make a baking soda and vinegar rocket How to make a baking soda and vinegar rocket How to make a baking soda and vinegar rocket

Create a nose cone for the rocket by cutting a circle out of construction paper, using scissors to make a cut to the center, and bending it into a cone shape that you can tape to the end of the tube opposite the film canister so it looks like the second picture.

Step #3: Decorate

Step #4: Put baking soda on lid

How to make a baking soda and vinegar rocket

Put some baking soda on the inside of the film canister lid and smooth it out. In my case, I just had to add 1 teaspoon.

Step #5: Fill the canister

How to make a baking soda and vinegar rocket

Hold your rocket upside down and fill the film canister about halfway or so with vinegar. If you want it to go faster, add more. But beware, don’t make the same mistake it did when I added too much vinegar. (It exploded in my hands, ouch!)

Step #6: Close lid and step away

How to make a baking soda and vinegar rocket

Put the lid with the baking soda on the canister, quickly set the rocket down, and step away. You need to do this very quick.
