Ever noticed how when you rub a balloon against your hair, it sticks to the wall? That’s static electricity in action! Learn more about this fun science concept with simple static electricity experiments, and everyday examples of static electricity. Enjoy hands-on physics experiments for kids!
Explore Static Electricity For Physics
What is static electricity? Imagine tiny, invisible particles called electrons acting like little magnets. Everything around you—your hair, a balloon, even your favorite sweater—is made up of these tiny particles. But here’s where it gets exciting: electrons can move!
💡Electrons are tiny, invisible particles that move around the center of an atom. Atoms are tiny building blocks that make up everything around us—like people, animals, water, and even the air.
When you rub two things together—like a balloon on your hair—the electrons shift from one object to another. This movement creates an electrical charge.
- The object gaining extra electrons becomes negatively charged (like a minus sign ➖).
- The object losing electrons becomes positively charged (like a plus sign ➕).
And guess what? Opposite charges attract, and like charges repel! That’s why:
🎈 A balloon rubbed on your hair can stick to the wall!
👩🦱 Your hair stands up because the strands are repelling each other!
This fun trick is called static electricity, and it’s like a tiny, invisible magic show happening all around you. Want to see it in action? Try rubbing a balloon on your sweater and then holding it near small pieces of paper—watch as they jump up like popcorn!

Static Electricity Experiments For Kids
Here are some simple and fun examples of static electricity experiments and demonstrations that are great for learning at home or in the classroom.
Rolling Can Static Electricity
The rolling can experiment provides a tangible demonstration of static electricity’s captivating nature! Grab a balloon and an aluminum can to get started.
Bending Water
Can you bend a stream of water with static electricity? It’s an easy and fun science demonstration for people of various ages to try.
Static Electricity with Balloons
Rub a balloon against your hair or a piece of wool cloth, and then place it near small pieces of paper. The paper should be attracted to the balloon, demonstrating the effect of static electricity. What happens when you use different types of cloth?
We’ve tested lightweight paper, tissue paper, and tinsel! What else can you test?
Static Electricity with a Plastic Straw
Rub a plastic straw with a piece of cloth or fur and then use it to pick up small pieces of paper or confetti. The static charge on the straw will make the paper pieces stick to it.
Static Electricity with a Plastic Bag
Inflate a plastic bag and rub it against your hair or a piece of fabric. Hold the bag near a wall, which should stick to the wall due to the static charge.
Static Electricity with a Balloon and Salt and Pepper
Rub a balloon against your hair and then bring it to a plate of salt and pepper. The salt and pepper will be attracted to the balloon, demonstrating the power of static electricity.
Static Electricity with a Comb and Water
Run a comb through your hair and bring it near a thin stream of water. The water will be attracted to the comb and bend towards it.

Static Electricity with Cornstarch Goop
Make electric goop! Mix up a batch of cornstarch oobleck and test out the power of static electricity with a balloon.
Static Electricity Butterfly Experiment
Make a butterfly’s wings move! Explore the power of static electricity.
Lightning Static Electricity Experiment
Explore how static electricity in clouds leads to lightning. Use simple materials like a balloon and a spoon while learning about thunderstorms and lightning.
Try This Static Electricity Experiment with a Comb
This comb and water static electricity experiment is a fun way to demonstrate the principles of static electricity to kids.
Supplies:
- A plastic comb (the type with fine teeth works well)
- A running faucet or a source of water
- A small piece of dry paper or a small piece of tissue
- A piece of dry cloth or wool (a piece of wool fabric or a wool sweater works great)
Instructions:
STEP 1. Rub the dry comb vigorously against the dry cloth or wool for about 20-30 seconds. This rubbing creates a buildup of static electricity on the comb.
TIP: If the comb is not dry, be sure to dry it with a paper towel or cloth so that it’s completely free of water.
STEP 2. Have a running faucet nearby or fill a small sink with a shallow layer of water.
STEP 3. Now, while still holding the comb, bring it near the running faucet or the water surface without touching it.
You should see that the water stream bends toward the comb, as if the comb is magically attracting the water.
TIP: You can also try this with a small piece of tissue instead of running water. When you bring the charged comb close to the tissue, you’ll notice that it’s attracted to the comb.
What is happening?
Rubbing the comb against the cloth or wool picks up extra electrons and becomes negatively charged. The water or tissue has a positive charge.
Opposite charges attract, so the negatively charged comb attracts the positively charged water or tissue. This is a simple demonstration of the principles of static electricity.
Explain this concept to the kids while experimenting, and encourage them to try it themselves. It’s a great way to make science fun and interactive for children.
Everyday Examples of Static Electricity
Here are some everyday examples of static electricity that you can explain to kids. These examples help kids understand that static electricity is all around us, and it can be both fun and surprising when we see it in action. It’s like a little bit of science magic happening every day!
Petting a Cat or Dog: When you pet your cat or dog, you might feel a little shock when you touch their fur. It’s because of static electricity from friction between their fur and your hand.
Balloon on the Wall: When you rub a balloon against your hair and then stick it to the wall, it’s static electricity at work. The balloon becomes negatively charged from the friction, and it sticks to the wall, which has a different charge.
Walking on Carpet: Sometimes, when you walk on a carpet with socks, you may feel a shock when you touch a metal doorknob. This happens because you build up a charge by rubbing against the carpet, and when you touch the doorknob, the charge flows and gives you a little shock.
Socks and Jumping Beans: Sometimes, when you take off your socks after walking on a carpet, they might attract small items like jumping beans or bits of paper. The socks get charged as you walk, attracting other small objects.
Static Cling in the Dryer: When you take clothes out of the dryer, they might sometimes stick together or to the sides of the drum. This happens because of static electricity from the friction of the clothes rubbing against each other.
Balloons Stick Together: If you rub two balloons against your hair and bring them close together, they might stick together. This is because the like charges (both negatively charged) on the balloons repel each other.
Crackling Sounds in the Winter: In cold, dry weather, you might hear crackling sounds when you touch things or remove your winter hat. That’s static electricity being discharged.
Lightning: Explain how lightning during a thunderstorm is a massive example of natural static electricity. It happens when negative charges build up in the clouds and discharge as a bright bolt of lightning to the ground.
