What is the Bernoulli Principle?

April 29, 2013 By Emma Vanstone 3 Comments

This experiment is a super easy air pressure activity to demonstrate the  Bernoulli Principle .

What is Bernoulli’s principle?

Bernoulli’s principle states that the pressure of a fluid decreases as its velocity increases.

Bernoulli Principle Demonstration

What you need:.

A large empty water bottle bottle

A rolled-up ball of paper, small enough to sit inside the mouth of the bottle.

How to demonstrate the Bernoulli Principle with a bottle and paper

Place the bottle on the edge of a table and put the ball of paper inside.

Try to blow the paper into the bottle.

The ball will wiggle around and shoot back out towards you.

What’s happening?

One of the principles that help to keep aeroplanes in the sky also applies to this neat little experiment. The key point is that moving air is at a lower pressure than still air. This is the Bernoulli Principle .

In the case of the water bottle, you can’t blow any more air into the bottle as it is already full of air!

When you try to blow into the bottle, the air is deflected around the sides (very little moves past the piece of paper). This means that the air pressure in front of the ball of paper is lower than behind, and so the paper flies out.

Aeroplane wings are specially shaped so that air travels faster over the top of the wing than over the bottom surface. Again, the pressure is lower above than below, and the wing is “pushed” upward by the higher-pressure air – called lift. The faster the plane moves forward, the bigger the lift it experiences.

Who was Daniel Bernoulli?

Daniel Bernoulli ( 1700-1782 ) was a brilliant Swiss mathematician and physicist who was born in the Netherlands and later moved to Switzerland. Daniel came from a family of scientists. His father, Johann, was an early developer of calculus, and his uncle Jacob made valuable contributions to the theory of probability .

Daniel Bernoulli’s major contributions to science include working on the kinetic theory of gases, measurement of risk and The Bernoulli Effect .

5 Ways to Demonstrate Air Pressure to Children

• Topics & Resources

Date Published:

Nov 22, 2010

Aurora Lipper

This story was updated on 10/11/2022.

Note: when conducting at-home science experiments with children, an adult should always be present. Even the simplest experiments have the potential to go wrong.

The ordinary pressure of the air surrounding us is 14.7 pounds per square inch—but this can change based on a few factors, such as when the wind blows or a car or airplane accelerates. Wherever the air pressure is higher, there will be a stronger force or push against an object. Similarly, when an air particle speeds up, it actually “pushes” less.

Imagine that fast-moving air particles are in so much of a hurry that they don’t have time to apply force—this is the principle used to make airplanes fly. When a plane moves along the runway, the air above the wing speeds up, lowering the pressure so that the air below the wing can push the plane upward.

Interested in testing out these principles in a more tangible way? Try one or more of the following experiments:

Water Glass Trick

Step 1: Fill a cup one-third with water.

Step 2: Cover the entire mouth of the cup with an index card.

Step 3: Holding the card in place, take the cup to the sink and turn it upside down.

Step 4: Remove your hand from underneath.

Voilà! Because the water inside the cup is lighter than the air outside, the card is held in place. This is due to about 15 pounds of force from the air pushing up, while the force of the water pushing down is only about one pound of force.

Fountain Bottle

Step 1: Fill a 2-liter soda bottle half full of water.

Step 2: Take a long straw and insert it into the mouth of the bottle.

Step 3: Wrap a lump of clay around the straw to form a seal.

Step 4: Blow hard into the straw—then stand back.

When you blow into the straw, you’re increasing the air pressure inside the sealed bottle. This higher pressure pushes on the water, forcing it up and out of the straw.

Ping-Pong Funnel

Step 1: Put a ping-pong ball inside the wide part of a funnel.

Step 2: Blow hard into the narrow end of the funnel.

Step 3: You’ll notice that the ball doesn’t pop out of the funnel—but why?

This is because as you blow into the funnel, the air moves faster and lowers the air pressure underneath the ball. Because the air pressure is higher above the ball than below it, it’s pushed down into the funnel—no matter how hard you blow or in which direction you point the funnel.

The Million Dollar Bet

Step 1: Place an empty water or soda bottle down horizontally on a table.

Step 2: Roll a piece of paper towel into a small ball about half the size of the bottle opening.

Step 3: Tell a friend you’ll pay them one million dollars if they can blow the ball into the bottle.

Don’t worry about losing money—because this is impossible. No matter how hard someone tries to force more air into the bottle, there's no room for it. The air will flow right out, pushing away the paper ball.

Kissing Balloons

Step 1: Blow up two balloons and attach a piece of string to each.

Step 2: Place one balloon in each hand, holding them by the string.

Step 3: Position the two balloons so they are at your nose level and six inches apart.

Step 4: Blow hard into the space between the balloons.

As you lower the air pressure in that space between the balloons, the pressure of the surrounding air becomes higher. This automatically pushes the balloons together, causing them to “kiss.”

Balloon and Jar Air Pressure Experiment

by Science Explorers | Mar 29, 2021 | Blog | 0 comments

Air pressure experiments for children are a fun way to introduce kids to a new scientific concept. Kids and adults alike have a blast with this balloon and jar air pressure experiment. The experiment shows children what happens when the air pressure inside a jar changes by using just a few materials. It’s the perfect lesson for elementary school-age children with adult supervision.

Learn more about our virtual and in-person science camps!

What You’ll Need

To perform the experiment, you’ll need:

• Water balloon.
• Piece of paper.

Safety Note

This experiment uses fire. Children must be supervised and should not perform the experiment on their own.

How to Conduct the Experiment

Follow these instructions to suck a water balloon into a jar using air pressure:

• Fill the balloon:   Fill the water balloon until it’s slightly wider than the neck of the jar and tie the balloon.
• Place the balloon on the jar:   Place the jar on a flat surface and rest the balloon on top of the open jar.
• Demonstrate with the water balloon:   Help the kids push down slightly on the balloon to show them it won’t fit inside the jar.
• Remove balloon:   After demonstrating, remove the balloon from the container.
• Get your matches:   Light a piece of paper with a match and drop it in the jar.
• Place the balloon again:   When the fire starts to grow, place the balloon back over the mouth of the jar.
• Watch the reactions:   Observe what happens to the balloon and the fire. The balloon will begin to shake, and the fire will be extinguished as the balloon is sucked into the jar. The balloon will be sucked about halfway into the container.
• Let the kids try:   Once the fire has died and the jar has cooled, have the children try to remove the balloon. It will be a little challenging!
• Safely remove the balloon:   To remove the water balloon from the jar, start by turning the jar sideways. Place your finger between the container and the balloon to release the suction. The balloon should come out easily after that.

Children will love doing this experiment over and over. To make this air pressure experiment even more fun for kids, let each child pick a balloon to decorate before you fill it with water. This allows children to observe any differences between how the balloons behave, such as which balloon was most difficult to remove and which one worked best.

The Science Behind the Experiment

This experiment is all about air pressure. When you first place the filled balloon atop the jar, air pressure prevents you from pushing it inside. The air trapped inside the jar has nowhere to go, since the balloon covers the opening. At this point, the air pressure within the jar is the same as the air pressure outside it, making it impossible to fit the balloon in.

But when you add the lit piece of paper to the jar, things change. The burning paper causes the air inside the jar to heat up and expand. As the fire grows, the air in the jar will start escaping around the sides of the balloon. When the balloon begins shaking that’s how you know the air is escaping.

The balloon acts as a one-way valve, allowing air within the jar to escape but preventing new air from entering. With less air in the jar, the air pressure drops. At this point, the air pressure within the jar is lower than outside it, which causes the balloon to get sucked in.

How to Demonstrate Air Pressure with Balloon

How to fit an object through a smaller hole not easy, that is for sure. but we can turn towards science and get some help from atmospheric pressure. so let’s do just that – fit the balloon into the glass jar by using the air pressure, article contents.

What is air pressure or atmospheric pressure?

The pressure that is all around us is called air pressure or atmospheric pressure . We define it as the force exerted on a surface by the air above the object, as the gravity pulls that air towards the ground. Another popular definition: Atmospheric pressure is the force per unit area exerted by the mass of the atmosphere as gravity pulls it to Earth.

We measure atmospheric pressure or barometric pressure with a device called a barometer . The unit we use to measure atmospheric pressure is atm. Atm stands for the standard atmosphere and it’s a unit of pressure defined as 101,325 Pa (pascal). Atm is equal to Earth’s average air pressure at sea level.

We already talked a lot about air pressure in How to Demonstrate Air Pressure with Can Crush Experiment. We suggest you check it out for more information.

What are balloons made of?

Balloon production came a long way from when it was first invented. The first balloons were made from animal intestines and bladders. Nowadays, balloons are made mostly from latex , rubber, and nylon fabric .

These materials are long particles called polymers . Polymers are elastic , which means they will scratch when you pull them and shrink when you let them go. As mentioned, latex, rubber, and nylon fabric are all made of polymers and that is why they are the most popular materials to produce balloons nowadays.

We already talked a lot about balloons in the 5 amazing Balloon experiments article, so check it out to learn more. Also, we recommend you check this great video that shows the industrial process of balloon making .

Required materials for balloon air pressure experiment

• Balloon . Any balloon will do but we recommend using a water balloon. Water balloons are small enough to best fit the jar opening and are designed to be filled with water. Also, they come in packs so you will have some spare balloons if the balloon breaks before the experiment is done.
• Glass Jar . Any glass jar will serve as long as the balloon can fit through the opening. A pickle jar, olives jar, or jam jar will be great for the experiment.
• Lighter or matches . We will need a lighter or matches to set the paper at flame before putting it into the jar. Have some spare matches or enough gas in the lighter if you need to light the fire again since the fire can die out in the jar.
• Piece of paper . Any paper will be great as long as it wants to burn. Not much paper is needed, just enough to fill the bottom of the jar. So the bigger the jar, the bigger piece of paper you will need.
• A glass of water . Since we are dealing with fire, it is always good to have some water by hand. That is why we recommend you have some water in a glass or bottle next to you when conducting this experiment.

Instructions to make balloon air pressure experiment

If you would rather like to watch the “how-to” video for this experiment, we have added the video at the beginning of the article. And for a step-by-step guide, continue reading the instructions below.

Warning : Since this experiment requires some fire, it is strongly recommended to conduct the activity outside, in a safe environment. Also, this activity should be conducted under the supervision of adults for all under-aged children.

• Take the balloon and fill it with water. We need water inside of the balloon so it can withstand the heat from the fire and not explode which can happen with only air inside. A water balloon is the best for this activity since it is made for holding water. Attach the balloon to the water pipe and fill the balloon.
• After the balloon is filled, remove it from the pipe, but don’t tie it up just yet. Take the glass jar and see how the balloon fits the opening . Make sure the balloon can’t fall inside of the jar, but also make sure it is not that much bigger than the opening. You can spill some water out of the balloon if it is too big to make it fit the jar opening better.
• Tie the balloon . This can be tricky but there are many ways we can do this. If you can’t use the balloon end to tie it up around itself, you can use some wool or thin rope to tie the balloon. After tying the balloon, we are ready for the experiment.
• We strongly suggest you go outside for the next steps. There could be smoke and you probably don’t want the smoke indoors.
• Take a piece of paper and light it with matches or a lighter . Make sure the paper is burning and if the fire goes off, light it again. The fire must be burning to create pressure.
• Put the burning paper inside of the glass jar . If the paper is still burning inside, proceed to the next step. If the fire went off, light the paper again.
• Put the balloon on top of the jar opening . Observe what is happening. You will see the balloon being sucked inside of the jar due to created pressure.
• After the balloon is sucked in, we recommend you take a prepared glass or bottle of water and pour some water inside of the jar . This is a safety precaution to make sure there is no more fire.
• And you are done! Now it’s time for discussion about what happened in the experiment.

The science behind the air pressure experiment with a balloon

When we place the inflated balloon or balloon filled with water atop the jar, the balloon won’t fall through the opening. Since the air inside of the jar is preventing it from falling down, and the balloon covers the whole opening, it will just sit atop the jar. At this time, the air pressure is the same inside, and outside of the jar.

To get the balloon sucked into the jar, we need to create the difference in air pressure . When we start the fire inside the jar, the temperature rises and the air inside gets warm . Warm air spreads more and is less dense, which means the pressure decreases since the air gets warmer.

When we put the balloon on top of the jar, we prevent new air from coming inside of the jar . The balloon acts as a one-way barrier , preventing new air to come in but letting the hot air go out. As the air inside of the jar gets warmer, it will escape the jar, but new air won’t come in. If you see a balloon shake, that means the hot air is coming out and shaking the balloon. 

And as more air goes out of the jar, the difference in air pressure becomes higher – low pressure inside of the jar and higher pressure outside of the jar.

And since the pressures want to achieve equilibrium again, the balloon is sucked in until the air outside can again find some way to enter the jar – by pushing the balloon inside of the jar and opening the hole for the free flow of air again.

What will you learn and what skills will you develop?

• Learning about air pressure . You will learn about what is air pressure, differences in air pressure, and how to demonstrate different air pressures. Also, you will see what happens when air pressure is out of balance.
• Learn about balloons . You will learn about balloon properties and the materials they are made of which is all part of the chemistry knowledge.
• Conducting scientific experiments . Demonstrating air pressure with a balloon is a scientific method and you will learn how to plan, prepare, conduct experiments, and in the end analyze and draw conclusions.
• Develop judgment and critical thinking . By talking about procedure and results, we develop our analytical thinking and judgment. We can also discuss what can be done differently and further develop our divergent thinking .
• Build awareness about needed safety precautions . You will build awareness and learn about safety measurements that we should always take when doing experiments. In our case, to go outside and have water close by since we were making fire.

We hope you enjoyed this experiment and learned something new about atmospheric pressure. If you’re interested in more similar activities and fun experiments, we have some recommendations:

• As already mentioned, if you want to demonstrate air pressure with one more activity, you can try the Can Crush Experiment .
• Another great way to see how air pressure works is by getting the water raise. You can see how to do that in the Candle in the vacuum experiment .
• And if you just want more balloon activities, we have plenty more in 5 amazing Balloon experiments article.
• We also recommend another interesting and simple experiment to demonstrate buoyancy with the Orange density experiment .

We wish you happy and successful experimentation! But no pressure 😉

Bernoulli’s principle for kids.

Have you ever wondered how do birds and airplanes fly when they are much heavier than air? You’ve probably figured out that their  wings are  involved somehow….. Well back in 1738 a mathematician and scientist named Daniel Bernoulli studied this phenomenon and discovered that as air moves around an object, it creates different pressures on that object. Faster air means less pressure, and slower air means more pressure. Now we can use the Bernoulli principle for kids to understand why birds, airplanes, and in this experiment – our ping pong ball can fly.  In this  bernoulli experiment , children will create a  floating ping pong ball by using Bernoulli’s principle! This  air pressure experiment  only takes a couple minutes, but is a fun and memorable  science experiment to help kids understand this fascinating concept. Try this  bernoulli principle experiment  with preschoolers, kindergartners, grade 1, grade 2, grade 3, grade 4, grade 5, and grade 6 students.

Bernoulli’s principle experiment at home

To try this  physics experiment for kids on energy you only need a couple simple materials:

• construction paper (any color)
• bendy straw
• ping pong ball

Bernoulli’s principle experiment

The technique for this  energy experiment is simple, children trace a circle about 6″ in diameter on their piece of colored paper.

Physics experiments for kids

Then students will carefully use scissors to cut out the circle.

Floating ping pong ball

Next, cut the radius. If you recall from math class, the radius is the straight line from the center of the circle to the outside of the circle.

Air Pressure Experiment

pull the two sides of paper around the radius so they overlap and tape into place to make a cone.

Bernoulli’s principle experiments

Insert the smaller part of the bendy straw into the bottom of your paper cone. Securely tape in place so there are no gaps for air to escape.

Bernoulli principle for kids

Put ping pon ball in over the paper cone you created with one hand and in the other blow a constant, staed stream of air to make the ball levitate. Allow kids time to continue making the ping pong ball float as they experiment with air flow and air pressure to make the ball fly.

NOTE: This only works if you blow hard enough so that there is a steady fast stream of air around the ball. If you blow slowly, then the pressure goes back up and the ball falls.

Science for Kids

Once kids have had a chance to experince  Bernoulli’s principle first-hand in this EASY floating ball experiment, it’s time to explain they why . Basically in this simple science project we created an area of low pressure around the ball by blowing into the straw. When you blow in a fast thin stream (because directs the straw focuses the air to make it thin), the fast air is able to move around the sides of the ball instead of simply pushing it upward from below. If you observe the ball closely as it levitates in the air, you will see that it wobbles in the low-pressure area. The ball is trying to escape the low-pressure air. The high-pressure air does not allow the ball to escape and pushes the ball back into the low-pressure area.
