7. Repel Glitter with Dish Soap

Have you ever pondered why dish soap repels glitter? It may seem like sorcery, but it’s actually science! This is due to Bernoulli’s principle. This states that, when the speed of a fluid such as air or water rises, its pressure decreases.

Here’s how you can recreate this at home:

  • Materials:
  • Dish soap
  • Glitter
  • A shallow dish or bowl
  • A pipette or straw
  • Water


  1. Fill your shallow bowl halfway with water.
  2. Put in a few drops of dish soap and mix.
  3. Sprinkle the glitter on top of the water.
  4. Using your pipette or straw, blow a steady stream of air across the surface of the water. You should observe the glitter move away from the airflow and toward the edges of the dish.

So, why does this occur? The airflow from your pipette or straw forms a zone of low pressure, which pulls the glitter particles to it. However, as the glitter gets closer to the airflow, the air speed increases, causing the pressure to decrease further. This heightened difference in pressure between the high-pressure area around the glitter and the low-pressure zone around the airflow causes the glitter to move away from the airflow and towards the edges of the dish.

This experiment is a great way to introduce kids to Bernoulli’s principle and the concepts of air pressure and fluid dynamics. Plus, who doesn’t love playing with glitter?

Pro tip: Experiment with different shapes and sizes of dishes to observe how the glitter moves in unique patterns.

8. Blow the Biggest Bubbles You Can

Blowing the biggest bubbles is the science experiment we’re talking about. Bernoulli’s principle is the keyword. It states that as the speed of a gas or fluid increases, its pressure lowers. This is why planes fly and liquids move through pipes. With bubbles, the air around it forms a pressure difference which causes it to expand.

The steps:

  1. Mix soap and water for bubble solution.
  2. Dip a straw in the solution.
  3. Gently blow air into the straw.
  4. Create a vortex by twisting the straw.
  5. Release the bubble and watch it grow!

The vortex increases the air speed, so it reduces the bubble pressure, making it bigger. The bigger the vortex, the bigger the bubble.

24. Mummify a Hot Dog

Ever wanted to know what mummification does to a body? Now’s your chance! Let’s learn about the ancient practice by mummifying a hot dog!

First, we must understand Bernoulli’s principle – when the speed of a fluid increases, its pressure decreases. This is used to dry out the body and prevent decay.

Gather these supplies:

  • Hot dogs
  • Baking soda
  • Salt
  • Small container
  • Cloth strips


  1. Mix salt and baking soda in the container.
  2. Cut the hot dog and rub the mixture over it.
  3. Let the hot dog sit for a few hours.
  4. Rinse the hot dog.
  5. Wrap it with cloth strips.
  6. Let the hot dog sit in a dry place for weeks.
  7. Unwrap it and see how well it was mummified!

This experiment combines archaeology, science, and chemistry. Invite your friends and family and start your adventure!

Pro tip: Try different mixtures of salt and baking soda for the best mummification.

Fire Science

Fire is fascinating! Kids are naturally drawn to it. Parents, though, may be worried about letting their children play with fire and ignite objects. The answer? Science experiments! These offer a safe place for kids to explore the properties of fire. Plus, they learn vital safety lessons.

Here, we’ll discuss Fire Science experiments that are engaging and fun. Let’s dive into this exciting world!

25. Extinguish Flames with Carbon Dioxide

Excite your kids about science! Let them try this fun experiment that shows how carbon dioxide can extinguish flames. Carbon dioxide is often used in fire extinguishers; it pushes out the oxygen and smothers the fire quickly.

Here’s how to do it:

  1. Gather materials: Candle, tall glass/jar, baking soda, vinegar and a plate.
  2. Pour baking soda onto the plate.
  3. Add vinegar to it – this creates a chemical reaction, producing carbon dioxide gas.
  4. Quickly pour the gas into the jar/glass with the lit candle. Cover the flame completely.
  5. The carbon dioxide pushes out the oxygen and the flame is extinguished.

This experiment explains Bernoulli’s principle – when a fluid’s velocity increases, its pressure decreases. The high-speed carbon dioxide reduces the pressure around the candle and the flame goes out.

Pro tip: Use this as a starting point to talk to your kids about fire safety and why it’s important to have smoke detectors and fire extinguishers.

Fun Fact: Carbon dioxide is a non-toxic gas that occurs naturally in the atmosphere. It makes up less than 1% of the air we breathe, but it’s necessary for life on Earth.

Joke: Why did the firefighter wear red suspenders? To keep his pants up while fighting fires!

Emotions: Get your kids excited about science! They’ll love seeing how carbon dioxide puts out flames and you’ll love how much they’re learning. Have fun!

Magnifying Wonders

Tired of your kids glued to screens? Introduce them to science! These experiments not only provide entertainment, but also teach curiosity, creativity and critical thinking. We’ll be discussing the “Magnifying Wonders” science experiments for kids. Get ready to be amazed!

Uncover the powers of magnification with these experiments. Let the wonders begin!

26. Make a Magnifying Glass from Ice

Ever tried to make a magnifying glass from ice? Sounds like magic, but it’s possible! Kids will love this science experiment. It relies on Bernoulli’s principle, the same that explains why planes fly.

Here’s what you need:

  • clear plastic wrap,
  • a cup of water,
  • an ice cube tray,
  • a piece of paper or cardstock paper, and
  • a pair of scissors.

To make your magnifying glass:

  1. Fill the tray with water & freeze it.
  2. Stretch the plastic wrap tightly over a glass.
  3. Place the wrap-covered glass on paper & trace the bottom.
  4. Cut out the circle you traced.
  5. Put an ice cube on the center of the circle.
  6. Hold the paper up to your eye & focus on a small object.

The plastic wrap creates a curved surface over the glass due to Bernoulli’s principle. Lower pressure means things move faster. The water on the plastic wrap gives the ice a curved shape, bending light & allowing you to magnify something. This is a good way to engage kids & explore the magic of science. Try repeating the experiment with a different material & see the impact!

Physics Fun

Searching for fun ways to teach physics to kids? Physics can feel intimidating but doesn’t have to be! Here, we’ll discover the best physics experiments for kids. These experiments are both educational and entertaining! All you need are everyday household items. Get ready to get enthusiastic about physics and spark your child’s interest!

Let’s explore some of the best physics experiments for kids:

27. Do the Archimedes Squeeze

If you’re looking for a fun physics experiment to do with your kids, try the Archimedes Squeeze! It’s based on Bernoulli’s principle. You’ll need a plastic bottle, cap, straw, scissors, and small clay or playdough.


  1. Cut the bottom of the bottle.
  2. Poke a hole in the cap using the straw.
  3. Secure the straw with clay or playdough.
  4. Inflate the balloon over the open end of the bottle.
  5. Squeeze the sides of the bottle.

As you squeeze, you’ll watch the balloon inflate. This happens because air pressure decreases as air moves through the straw. This is a great way to teach kids about Bernoulli’s principle!

Plus, you can try different sizes and shapes of containers to see how it affects the flow of air. Enjoy!

28. Step Through an Index Card

Step Through an Index Card is a cool experiment to show Bernoulli’s principle. Bernoulli’s principle states that when air moves faster, the pressure is lower. All you need are an index card, scissors, and a straw.

Cut a rectangular hole in the middle of the card. Make sure it’s two-thirds of the card’s length. Blow air over the hole with the straw. You’ll see the card lift and stay in the air.

When air moves faster over the hole, the pressure is lower. This causes higher air pressure below the card, pushing it up.

This is a great way to teach kids physics and Bernoulli’s principle. It also helps them with problem-solving and critical thinking. They can do the experiment multiple times, changing the size of the hole and the rate of blowing air.

Pro tip: Have your child make a journal to document their observations and outcomes. This will help them track the changes and develop their scientific reasoning.

29. Stand on a Pile of Paper Cups

Do you know you can stand on a stack of paper cups without crushing them? It may seem like magic, but it is actually science! This experiment is based on Bernoulli’s principle. It states that as the speed of air increases, its pressure decreases.

To do this experiment at home, you need 15 paper cups, a balloon and a long sheet of paper or cardboard. Follow these steps:

  1. Stack 5 cups at the bottom, then 4, 3, 2 and 1 on top.
  2. Cut the cardboard/paper into a circle, which should fit on top of the tower.
  3. Inflate the balloon and pinch it shut.
  4. Hold the balloon above the cardboard circle.
  5. Release the pinch so air rushes out and hits the cardboard.
  6. Quickly place the circle on top of the cup tower.
  7. Step on the cardboard and stand up!

The air creates a low-pressure zone that allows the cups to support your weight. It is an excellent way to introduce kids to Bernoulli’s principle and air pressure. They can also learn about engineering and balance while stacking the cups and balancing on the tower. Plus, it is fun!

Try to make the experiment more challenging by standing on one foot or holding a book while balancing on the tower.

So, if you are looking for a cool science experiment to do with your kids, grab some paper cups and a balloon and see if you can stand on a pile of them!
