Learning physics does not always require sophisticated equipment or specialized laboratories. With a few simple materials available at home, it is possible to conduct fascinating experiments that can spark the scientific curiosity of young minds. This article explores various engaging and easy-to-do projects that allow one to explore the fundamental principles of physics while having fun.
Create a rainbow in a bottle
This experiment introduces children to the refraction of light. To create this colorful illusion, you will need a glass or plastic bottle, water, and a light source, such as a flashlight. Fill the bottle with water and direct the flashlight to project light through the water. Children can observe how light rays break down, creating a rainbow.
Make an eggshell disappear
This experiment illustrates the principle of diffusion. Take an eggshell and immerse it in vinegar for 24 hours. The vinegar reacts with the calcium carbonate in the shell, causing it to dissolve. At the end of this experiment, you will have a translucent membrane, which allows for the explanation of the concept of chemical reaction and the importance of acids and bases.
Make an iceberg
Think of a melting ice simulation to explore the concepts of states of matter. Fill a container with water and place a small bowl or cup in it. Add colored water with food dye into the bowl. Place everything in the freezer. As the ice starts to melt, observe the state changes and discuss the implications of glaciers melting in the context of climate change.
Make the pepper flee
This fun experiment demonstrates the surface tension of water. Fill a shallow dish with water and sprinkle some pepper on top. Dip your finger in dish soap and then touch the surface of the water. The pepper will instantly move away. This helps explain how soap acts on the surface tension, altering the properties of water.
The traveling water
Generate a flow of water using capillarity by placing one end of an absorbent paper in water from one container and the other end into a second empty container. This demonstration shows how plants use capillarity to transport water from their roots to their leaves. Kids can see the water travel in a fun and visual way.
Create a homemade lava lamp
A homemade lava lamp is a wonderful way to learn about density and the behavior of liquids. Fill a bottle with water to about one-third, add some oil, and then a few drops of food coloring. When you add baking soda, the air bubbles created will make the color rise and fall, mimicking movement in a real lava lamp. This experiment helps to understand the differences in density between liquids.
Experiments with unpoppable balloons
This experiment is perfect for illustrating the principle of pressure. Take a balloon and poke it with a needle. You will find that the balloon does not pop as long as the pressure is evenly distributed, for example, by placing the balloon on a soft surface. This opens the discussion about atmospheric pressure and different types of forces.
Experimenting with water
Water is an excellent agent for exploring various physical concepts. For example, by testing buoyancy with different objects to teach bouyancy and fluid dynamics. Children can conduct experiments to guess whether an object will sink or float in water and then check their hypotheses to learn more about densiometry.
Understanding supercooling
This captivating experiment allows you to understand the principles of thermodynamics. Fill a bottle with distilled water and place it in the freezer without letting it freeze. When taken out, a disturbance can cause the immediate solidification of the water, illustrating a state of supercooling. A discussion about practical applications of this property, such as how modern refrigerators work, may follow.
For more autonomy, children can document their observations and results in a logbook. This develops their critical thinking and understanding of scientific methods. Discovering physics through simple experiments at home opens new perspectives and nurtures their scientific curiosity for the future.

Physics is a fascinating science but often perceived as complex. Yet, it is possible to learn its principles in a playful and accessible way through simple experiments performed at home. This article offers a range of scientific activities that will stimulate children’s curiosity while facilitating their understanding of physical concepts.
Create a rainbow in a bottle
With a few drops of food coloring, water, and oil, you can create a mini rainbow. By carefully adding the liquids, children will observe how different densities create a separation of colors, an excellent way to explain the concept of density and mixing.
Make water travel
This fun experiment will involve making water “travel” from one container to another using a piece of rope or string. This project allows for the explanation of the principles of capillarity and surface tension. Children will understand how liquids can move against gravity.
Make an iceberg
By mixing water, salt, and a little food coloring, one can create a floating “iceberg.” This experiment allows addressing the salinity of water and the principles of buoyancy. Children will observe how salt affects the density of water and, consequently, the ability of the object to float.
Make pepper flee
A little pepper, water, and soap will allow for an exciting experiment. By adding soap to a container of water with pepper, children will be able to observe how the pepper moves away from the soap. This is due to the surface tension of the water, stimulating discussion on the forces at work.
Understanding density with the floating egg
This experiment requires an egg, water, and salt. By adding salt to the water, children will be able to see a floating egg. This will illustrate the concept of density and the role that salinity plays in the buoyancy of objects.
Create a homemade lava lamp
With just oil, water, food coloring, and effervescent tablets, you can create a lava lamp. This playful project clearly shows how liquids of different densities interact and stack up against each other.
The unpoppable balloons
Use a simple technique to prove that, despite appearances, a balloon can be supported by a flame. By poking a burning balloon with a sharp object, children will learn how pressure and temperature play a role in the resistance of materials.
The science of magic milk
A little milk, food coloring, and dish soap are the ingredients necessary to perform an experiment that shows fascinating chemical reactions. Children will observe how soap breaks the surface tension of milk, creating colorful patterns.
Explore the world of fractals
Fractals are repetitive geometric figures that also exist in nature. By using simple drawings or free software, you can introduce children to repetitive patterns and explore the mathematical theories behind these incredible shapes.
The theory of chaos
With simple and visual examples, children can discover the theory of chaos through experiments like the Foucault pendulum or simulation games that show how small initial changes can create large effects. To learn more, check out this article on the theory of chaos.
