DIY Floating Ball Trick: A Magical Air Pressure Science Activity for Kids
The world of science is full of fascinating principles that can be demonstrated using simple, everyday objects. One of the most exciting examples is the DIY floating ball trick, an easy hands-on activity that mesmerizes kids and adults alike. With nothing more than a ping-pong ball and a hairdryer, children can watch a ball magically hover in mid-air. It feels like a trick, but it’s actually science — specifically Bernoulli’s principle.
This fun physics experiment for kids is perfect for classrooms, science fairs, homeschooling, or weekend family learning. Children not only get amazed by the floating ball but also learn how air pressure works to create balance and stability. The demonstration shows how air can act as a supportive force and explains why airplanes fly, why soccer balls curve in the air, and why shower curtains get pulled inward when the water is running.
This activity encourages curiosity, questioning, and hands-on learning. Best of all, it requires minimal preparation and uses materials you likely already have at home, making it one of the easiest science demonstrations to conduct.
What You Need
For this air pressure science activity, you only need two items:
Ping-pong ball
Hairdryer (set to cool mode if possible)
These simple materials allow children to safely explore a powerful physics concept. Ping-pong balls are lightweight, making them ideal for airflow experiments. A hairdryer provides a steady upward stream of air strong enough to support the ball. This demonstration works best indoors where the air is stable and wind won’t interfere.
How to Do the DIY Floating Ball Trick
Follow these steps for the perfect floating ball demonstration:
Step 1: Turn on the Hairdryer
Point the hairdryer straight upward. Make sure the airflow is consistent and strong enough to lift light objects.
Step 2: Position the Ping-Pong Ball
Hold the ping-pong ball above the airflow and gently release it. As the air hits the ball, it will begin to rise and hover.
Step 3: Watch It Float
The ball stays suspended in mid-air, balancing magically in the stream of fast-moving air. Kids can try slowly tilting the hairdryer to test how the ball follows the airflow without falling.
This interactive moment makes the activity even more exciting, helping children understand how airflow behaves and why the ball does not fall sideways.
The Science Behind the Trick: Bernoulli’s Principle
Although it looks magical, the reason the ball floats is pure physics. This demonstration is a visual example of Bernoulli’s principle, a fundamental concept in fluid dynamics that explains how air pressure changes when air moves faster.
Here’s what’s happening:
The hairdryer blows air upward at high speed.
Fast-moving air has lower pressure compared to the surrounding slower-moving air.
The ping-pong ball gets pushed into the low-pressure zone created by the airflow.
The surrounding higher-pressure air helps keep the ball centered in the stream.
Gravity pulls the ball downward, while the upward force of the air stream pushes it up.
These forces balance, allowing the ball to hover in mid-air.
This simple demonstration helps kids understand:
Airflow patterns
High pressure vs. low pressure
Gravity and upward force
Fluid dynamics in everyday life
The experiment also explains real-world phenomena like:
How aircraft wings produce lift
Why chimneys create drafts
How water flows faster through narrow spaces
Why balls curve when kicked or thrown
Children gain a deeper appreciation for how invisible forces shape the physical world around them.
Why Kids Love This Air Pressure Science Activity
The DIY floating ball trick is not only educational but also incredibly fun. Kids love it because:
It Looks Like Magic
The ball floating in mid-air feels impossible at first glance, making it instantly engaging.
It’s Interactive
Kids can experiment by moving the hairdryer:
Tilt it left or right
Raise or lower the ball
Try catching it mid-air
These small actions help them explore cause and effect.
It Encourages Curiosity
Children naturally ask:
How does the ball stay up?
Why doesn’t it fall?
What happens if the air slows down?
This curiosity leads them to seek scientific explanations.
It’s Safe and Easy
No complicated equipment or chemicals — just a hairdryer and a ping-pong ball.
It Builds Understanding Through Play
By observing and experimenting, kids learn scientific concepts without feeling like they’re studying.
Extensions and Variations
You can expand the activity with these fun challenges:
Try Different Objects
Experiment with:
Styrofoam balls
Lightweight balloons
Small paper balls
Kids can predict which objects will float and which won’t.
Change the Air Speed
Use the hairdryer’s settings to explore:
What happens at low speed?
What happens at high speed?
Tilt and Move the Hairdryer
Show how the ball follows the airflow even when the dryer is angled.
Multiple Ball Attempt
Kids can try adding another ball to see if both stay in the air.
Connect it to Real-World Science
Explain how this relates to airplane wings, sports, and weather patterns.
These variations help keep the activity engaging and open-ended.
Educational Benefits
This experiment helps develop:
Critical thinking
Prediction and hypothesis skills
Scientific reasoning
Understanding of forces and motion
Observation and analysis skills
Teachers often use this activity during physics lessons because it is easy to understand and extremely visual. It helps simplify abstract concepts for young learners by connecting them to real, observable results.
Conclusion
The DIY floating ball trick is a delightful blend of physics, curiosity, and hands-on exploration. Kids marvel as the ping-pong ball floats effortlessly in the air, and behind that magic lies the power of Bernoulli’s principle. This simple yet powerful demonstration turns complex air pressure concepts into something children can see and understand.
Whether you’re a teacher preparing a classroom science demonstration or a parent exploring fun physics at home, this activity is sure to engage, educate, and inspire. It teaches science through play, encourages experimentation, and builds a foundation for understanding how the invisible forces of air shape our world.

The secrets of angels and gods
Script written in South Korea Wonju Severance 53/8
Please help me spread this writing to Israel online communities.
Please help me upload this post to this sub reddit. I am very desperate.
The part that the assumptions of God can hurt/kill people is implied in the bible verses.
1. ln Job verses, the Old Testament in the conversation between God and Satan, "I allow you touching only his possessions, but not his life" we can see that the Satan had the ability to deal people’s lives. But this part should not be written in the bible so God disguised this story as him being tortured by skin illness.
Why was New Testment written?
Moreover, many saints were born through Jejus in the New Testament. Therefore it can be seen that the gods, who already had the ability to harm people, completed the doctrine by appointing one person in front of many people.
This could be because God from Israel required a justification after killing people and standing them up as an angel and insisting them to be their sex doll and clowns while being threathening their family's lives.
3. Eternal Life- the life of gods and angels
The gods and angels live along until the earth ends. At first they had used their abilities to help humans. But as you can see the part god and demon was talking, there were badness since the old testament in the bible. It is impossible for gods and holy spirits to be goodness because of the thousands of years passing by.
4. The reality of angels and gods that I assume
When Israel God (the king of all religions) gives the Holy Spirit to a human from each nation they become the God after that person dies. God is the King of sky who can stand angels and share abilities to each angels. Jejus is the second king with all abilities accepted except the power of sharing abilities. Angels are not picked among the naturally dead people but are killed by air pressure- one side blocking and one side flowing hard in the parts critical that leads to instantaneous death: the brain vains. All angels are chosen from humans to please gods using their bodies and charms- and they are chosen from very poor but loving families so that even after being tortured as sex dolls and clowns they could endure the pain as they see their families not being blind and get little help from god.
5. The miracles showed in the New Testments. How is it possible?
1) Please assume that God has the ability to read people's lives very quickly and detaily: karma
The Holy Spirit who accompanied Jesus had the power to read people’s karma. With this ability the holy spirit could keep track of where the bread and fishes were from the people passing by that could feed 5,000 people. This also can be inferred that God uses information of all humans to open his specific goals.
In this way God could fortell the future of enemies, the betrade of Judah etc in the bible. This miracle : 5 loaves and 2 fish was happened by God of Israel and holy spirits but through Jesus who was a living man so that many people could see and have faith in Christy, Catholic and Muslim.
2) Fix the sedentary
Please assume that holy spirit can move the soul inside the body so that the human body can be moved by holy spirits.
The ability to move the soul inside the body moves the body eventually which allows the sitter to stand. The holy spirit catched what the sedentary wanted to do and go by using karma of his mind and helped moving his body for his entire life. In conclusion the holy spirit inside the sedentary made everyone around him believe he has been healed by the Lord.
3) Fix the blind
Please assume that holy spirit can show
It would possible if the Holy Spirit attaches itself to one person for a lifetime and clearly shows the world in visions using hallucinations(vision)
4) . The Lord walks on the sea.
Please assume that holy spirit can practice visual hallucinations which is capable of colors too.
Hallucinations(vision)
5) .Turn water into wine.
Please assume that holy spirits can practice hallucinations(taste)
In the bible it is not said to be turned water to be wine but water tasted like wine. It was hallucinations(taste) so that everyone tasting the water could experience a the miracle.
6. Some of the angels’ abilities- you can anaylze bible with these assumptions
visual hallucinations - also capable of color
auditory Hallucinations - multiple sounds possible
touching hallucinations - sex appeal feelings
tasting Hwanmi - Appetite and the other way
smell Hallucinations - smell of food, etc.
Move Soul - Used to create human spirits to become an angel
Visibility of the soul - Human body can be seen even when wearing clothes
Air pressure - Air pressure makes blood circulate in people's blood vessels, so facial paralysis and crippled people can be corrected.
Reading the karma detaily with fast speed- A person's entire life can be read very quickly, and the gods catch and open the way for parts that people do not remember (God's power)
Making human spirits to angel- Raising a soul, making it into a Spirit, then folding it into a little angel
Covering- the ability to be present in front of people and saying in front of people
Confusion: the ability to disturb people’s mind and action in order to lead to the way that God has planned
