Explore Air Pressure With Kids

This egg in a bottle project is a fun way to learn about how changes in air pressure can result in a fascinating and seemingly magical outcome. All you need are a few supplies you would have in your own kitchen. That’s why we call it kitchen science!

Our science experiments are designed with you, the parent or teacher, in mind! Easy to set up, and quick to do, most activities will take only 15 to 30 minutes to set up and are heaps of fun! Plus, our supplies lists usually contain only free or cheap materials you can source from home!

Grab a bottle or jar, and find out how an egg can get sucked in the bottle. Get your kids to make a prediction, what do they think will happen to the egg when it seals the bottle?

Encourage kids to think critically and analyze why the egg moves into the bottle. They will learn to connect cause and effect, linking the heating and cooling of air to the movement of the egg.

This experiment may require some patience and persistence as kids troubleshoot and try different approaches to make the egg move into the bottle successfully. A great way to teach them the importance of perseverance in scientific exploration.

Extend the activity by getting kids to make observations, form hypotheses, conduct the experiment, and draw conclusions based on their findings. Kids can even share their findings and explain the science behind the experiment. This may involve discussing the concepts with peers, teachers, or parents.

Using The Scientific Method

The scientific method is a process or method of research. A problem is identified, information about the problem is gathered, a hypothesis or question is formulated from the information, and the hypothesis is tested with an experiment to prove or disprove its validity.

Sounds heavy… What in the world does that mean?!? It means you don’t need to try and solve the world’s biggest science questions! The scientific method is all about studying and learning things right around you.

As children develop practices that involve creating, gathering data evaluating, analyzing, and communicating, they can apply these critical thinking skills to any situation.

Helpful Science Resources

Here are a few resources that will help you introduce science more effectively to your kiddos or students. Then you can feel confident yourself when presenting materials. You’ll find helpful free printables throughout.

How Does An Egg Get Sucked Into A Bottle?

When you add the burning paper to the bottle or jar, the air inside gets hot. When the
air gets hot, it takes up more space inside the jar. The egg is placed on top of the bottle creating a seal that keeps the air from escaping.

As the air inside the bottle heats up, it expands. According to Boyle’s Law, when the volume of the gas (air) increases, its pressure decreases. Once the paper burns out, the air inside the bottle begins to cool.

As the air inside the bottle cools, it contracts, creating a partial vacuum. Outside air pressure is now greater than the pressure inside the bottle. The pressure difference between the inside and outside of the bottle causes the egg to be pushed into the bottle.

This experiment is a hands-on illustration of the principles outlined by Boyle’s Law. Boyle’s Law states that at a constant temperature, the pressure of a gas is inversely proportional to its volume. In simple terms, if you squeeze a gas into a smaller space, its pressure goes up, and if you let it expand into a larger space, its pressure goes down.

Turn It Into A Egg In A Bottle Science Project

Science projects are an excellent tool for older kiddos to show what they know about science! Plus, they can be used in all sorts of environments including classrooms, homeschool, and groups.

Kids can take everything they have learned about using the scientific method, stating a hypothesis, choosing variables, making observations and analyzing and presenting data.

Egg in a Bottle Experiment

Supplies:

  • Small mouth
  • Glass bottle or jar (A glass coffee or a spaghetti sauce bottle will work well)
  • Lighter or match
  • Paper strip
  • Peeled hard boiled egg that is slightly larger than the bottle’s opening

Instructions:

WARNING: Fire is involved so adult supervision is required!

STEP 1: Fold a paper strip and light it with a match.

Pin

STEP 3: Drop the burning paper into the jar or bottle and place the egg on top.

Pin

STEP 3: Now watch the magic happen.

Tip: If the egg does not pass easily into the jar, you can lubricate the edge of the jar
with vegetable oil.
